AR-15 lower receiver durability?

Gregg here. I've heard numerous things about the standard (aluminum) AR-15 lower receivers being used for larger calibers... how long will the lower last under that kind of stress? I mean, a .50 Beowolf is a rather powerful round, and I'm thinking, if it recoils as hard as it does (shot one magazine full...). Has anyone had problems with the lowers cracking/chipping (around any major "contact" points)? I'm really interested... 10 pts. to the most informational/educational answer.
All of you bring up a pretty good point, the components of the upper take almost all of the strain... I'm just trying to think of where the impact absorbed by the spring goes... (a force always acts on two or more "fronts", i.e. the back of the buffer tube and working the internals). Good answers everyone.

The lower receiver of an AR type rifle does not carry any of the load during firing. The bolt and barrel are locked together until the bullet passes the gas port in the barrel, then the bolt rotates to unlock. The force of recoil is carried straight back and into the shoulder of the shooter. The only lower receiver I have ever seen break was a rifle that was dropped off a shooting bench onto concrete. One of the lugs up front where the pin goes through broke off and that is not reparable on a cast aluminum part.

The Worlds Most Powerful Leadership Principle $15.59 Author and consultant James Hunter believes that-in the midst of numerous national corporate scandals-leaders must take a fresh look at leadership through the lens of some very ancient principles. Leadership that is authentic and effective is servant leadership-following the principles revealed in the life and ministry of Jesus Christ: Recently it struck me that if love changes people, which I know it does, it would seem to follow that God is the source of change and growth because He is love. Put another way, when people begin loving others through their efforts and behavior, God has the opportunity to work in the lives of both the giver and the receiver. In his new book, The World's Most Powerful Leadership Principle, Hunter demonstrates that leadership and character development are one. But the work, and even the pain, of changing one's self-breaking old, worn-out habits-is not easy. Hunter provides an uncomplicated, straightforward, three-step change process he has seen successfully employed by literally thousands of leaders to effect change in their lives and organizations and fulfill beneficial goals. This groundbreaking book will open the eyes of frustrated, disheartened leaders at every level and foster change for good at the personal, organizational, and societal level.

Home Theater Setup (surround Sound Speaker Setup)

Home Theater Setup (Surround Sound Speaker Setup)

I am going to assume that you already have a surround sound or home theater amplifier or receiver. There are 3 main home theater speaker configurations which you will see termed 5.1, 6.1, and 7.1 channel surround. You will also see mentioned the terms Dolby Digital, DTS, and Dolby Pro-Logic. There are some other formats such as Dolby Digital EX, Dolby Pro-logic IIx, Dolby TrueHD, DTS neo:6.1, DTS-ES, TrueSurround XT, and undoubtedly more, but they do not need to be addressed separately as the information below is also relevant for them.

Let's dispense with Dolby Pro-Logic first: if your receiver is only Pro-Logic (only older receivers at this point) you do not need to worry about 6.1 or 7.1 surround because your system can't use the extra speakers. The two factors relevant to our discussion are:

1. how many channels does your system permit, and
2. Do you want to buy that many speakers?

All the receivers that support more than 5.1 channels will also work fine with a 5.1 channel setup. Obviously, 7.1 will provide better surround sound than 5.1, but at the expense of two extra speakers. If you have a limited budget you will have to decide whether to buy 5.1 higher quality speakers, or go for cheaper speakers to allow for 7.1 channels. By the way, the .1 channel is the home theater subwoofer. The subwoofer is really needed for home theater. A system will work without it, but I don't recommend going without for home theater. The center channel is also very important for home theater, serving to anchor the sound to the video screen. These are the recommended placements according to Dolby Labs.

5.1 surround system:

A). Center speaker centered on video source

B). Subwoofer(s) in an arc with the main L & R speakers between speakers and video source

C). L & R front on a 22-30 degree angle from the sitting, on an equidistant arc connecting the center channel and subs

D). L & R surround equidistant and on a 90-110 degree angle from the sitting position

6.1 surround system:

A). Center speaker centered on video source

B). Subwoofer(s) in arc with the main L & R speakers between speakers and video source

C). L & R front on a 22-30 degree angle from the sitting, on an equidistant arc connecting the center channel and subs

D). L & R surround equidistant and on a 90-110 degree angle from the sitting position

E). Rear center 180 degrees (directly behind) the sitting position

7.1 surround system:

A). Center speaker centered on video source

B). Subwoofer(s) in arc with the main L & R speakers between speakers and video source

C). L & R front on a 22-30 degree angle from the sitting, on an equidistant arc connecting the center channel and subs

D). L & R surround equidistant and on a 90-110 degree angle from the sitting position

E). L & R rear equidistant and on a 135-150 degree angle from the listening position.

The descriptions above are the specifications for speaker placement according to Dolby Labs.

Subwoofer Setup

Your subwoofer may have a switch for Dolby Digital / Pro Logic. If your receiver is only capable of Dolby Pro Logic (only older systems) you need to use the Pro Logic inputs and set the crossover frequency properly to match with your main speakers. You may use an 80 Hz setting and adjust the volume properly for a reasonable output. I will not go into this further as almost all systems are capable of Dolby Digital output. If you have a Dolby Digital capable receiver (assuming you are using the sub for home theater purposes) set the switch to Dolby Digital even if you are using a Pro Logic source. The reason for this is that it allows your home theater receiver to manage the bass output & crossover frequency of the bass information. Your receiver will ensure the proper output to the sub in the case of Dolby Pro Logic source material. If you use the Pro Logic inputs only, Dolby Digital programs may not be reproduced properly. The same goes if you have multiple inputs on your sub. If your input is labeled LFE it is the equivalent of a Dolby Digital input. You want to use the input to the RCA style plug (or plugs) if you are using the subwoofer in a surround system. If you have speaker level binding post inputs, these are almost always for using the subwoofer in a non surround sound speaker setup. Preset the subwoofer level control to about halfway before running the white noise test tone to calibrate your receiver speaker levels. You absolutely must run the test and balance your speaker levels to have the surround system perform properly. Don't worry about the crossover frequency control on the sub for Dolby Digital or better systems. For Pro Logic set it to the point where bass in your main speakers drops off, (or 80 Hz if you can't find any info, and adjust from there for best sound) which will require looking at the documentation for your speakers.

If you are not using your sub in a surround system, you may, with advantage, use the speaker level inputs on the back of your sub. If you have relatively small speakers without much bass output this can provide a substantial sound quality advantage. The receiver left and right channels are connected directly to the subwoofer, and the left and right speakers connect to the speaker out connectors on the subwoofer. What this does is allow the sub to produce the low bass that the main speakers can not, which of course the other types of connections would do also. The advantage here is the fact that with the subwoofer connected this way, it filters the bass out of the signal to your main speakers, so they speakers never try to produce the bass that they can't handle. This results in clearer, cleaner sound and more volume capability from your main speakers.

Subwoofer placement is generally as below for other speakers. It is true that bass is omni directional and so you should be able to place a subwoofer anywhere, but as usual this depends on your situation. I play music loud, and can detect where the subwoofer is located by the feel of the vibrations. I find it very distracting to have the bass seem to come from the front of the room, but the vibrations of the bass coming from another direction. I therefore always prefer a subwoofer to the front of the room. The subwoofer should be adjusted in accordance with the setup (pink noise test) procedure of the amplifier it is being used with, if on a surround system. This usually means a crossover point of about 80Hz. If you have a phase switch or knob, set it to the position where the bass sounds the loudest. I also notice that most manufacturers recommend the sub be placed to the front of the room on a horizontal line with the main speakers. (Actually, to make all the speakers an equal distance from the listening position, they would form an arc.)

How to get the most out of your speakers & How to improve your sound quality for no extra money (unless you need speaker cable!)

The first consideration with a new speaker system is placement, and the second is wiring, both of which deserve consideration. We will cover wiring first with some generalities that apply to all kinds of speakers. The placement part will cover in home speakers only.

Wiring your speakers

First and foremost, wire selection can be very important. If your speakers are to be installed in-wall, you will need speaker cable rated cl3 or equivalent. If outdoor speakers, you should try to use what is termed a “direct burial” cable or equivalent.

Next, if you care about the sound quality at all, 22 gauge cable is not recommended. It can be used for very short runs, and is smaller for hiding, but due to resistance you will sacrifice some sound quality. I would recommend 16 gauge wire for most runs, unless you really want to get the best out of your speakers, in which case use 12 gauge or larger. For a long run I would recommend larger than 16 gauge cable. Click here to see our cable article and distance chart. I personally use a good audio quality 12 gauge cable myself, but you will pay more for cable this large. The advantages are better dynamics, and the amplifier can control your speakers better due to low resistance wire. As always, let the price point of your speakers determine the cable. Don't put expensive cables on cheap speakers, and vice versa. BTW, don't try to use romex (house wiring) instead of decent quality audio cable. Really, just say no. For so many reasons.

One common question is if fancy cable makes any difference. I must state here that many persons consider the very subject to be so much snake-oil. I personally believe that I can hear some differences, depending on the quality of the associated system. In other words, any hearable differences in cable will be more noticeable in a system with more resolution. Also consider that many listeners not selling cable claim to hear a difference. Consider any double blind tests carefully. I usually can pick holes in the logic behind most of these tests, and point out factors not considered. One perfect example was an amplifier test (by a major audio magazine) that level matched the amps, did a double blind test, and asserted the amps sounded identical, so they recommended that everyone buy the cheaper amp. Here's the rub: Under their exact conditions, which are not normal listening conditions, the amps sounded the same. Consider this unmentioned idea: The cheaper amp had less power output than the other, and under normal listening conditions, say with loud rock music, and inefficient or difficult to drive speakers would have pooped out before reaching satisfying listening levels, not to mention clipping and distorting from overdriving the amp. One problem with the double blind tests is, in order to be accurate, they have to control every factor in the universe that could affect the results, even unknown factors. The other is, in order to compare everything on an even playing field, they purposely diminish or nullify the differences, then triumphantly proclaim they are all the same. The perfect example from above is level matching at a volume level that does not stress the more easily stressed amp.

Polarity or Phasing of your speakers is very important. This means finding the wire with a stripe or writing on one side, and connecting that wire to either the + (red) or -(black) on the amplifier and the speaker. It does not matter whether the stripe on the wire connects to plus or minus, as long as it is the same at both ends, and on all speakers. I always connect the plus to the stripe, just to be consistent. If you get this wrong you will lose almost all your bass response, and voices will float around instead of being centered when they should be.

Home Speaker Placement

Ideal placement for best sound is going to vary with the type of speakers you have, but we can supply some good generalities. Obviously, for a surround system, you have some built in limitations. The center channel needs to go above or below center of your television, (or perhaps centered behind a projection screen) and the left and right front need to go to the left and right front. So on for the rest of the speakers. It should be added at this point that for surround sound placement the ideal is all 3 front speakers an equal distance from the listener. This actually places the front speakers on an arc. It is generally good to put rear surrounds a little higher than ear level so that all listeners get a better chance to hear all the speakers. Leaving aside the obvious details of surround sound, here is how to improve the sound of your system for free.

First, don't put anything in front of your speakers, and if they are placed in a cabinet make sure that the front of the speaker is even with the front of the cabinet. Also, keep in mind that some speakers such as the rear ported variety perform very poorly in cabinets. Make sure speaker ports, which may be in the front, rear, side or elsewhere, are not blocked. This goes for subwoofers also.

Stability is also important, your speakers need to remain stable at high volume levels. If they move with loud drum beats, your system will be robbed of punch and impact. If you use speaker stands make sure they are stable enough for the size of speakers you have. One quick tip is to use some blu-tack or mortite putty between the speaker and stand to improve the coupling and add stability. Spike on the bottoms of the stands work well for carpeted rooms.

Next, check out the sound of your speakers. Generally, most speakers sound better when aimed directly at the listener, and located at ear height. This is not always the case, however. If the treble or voices sound a little too sharp, then perhaps the speakers will sound better aimed straight out instead of at the listener.

Listen to the bass. Is it boomy, or lacking? If your speakers sound a little boomy, like they are in a barrel, bass response can probably be improved by moving your speakers farther from a wall or corner. If your speakers are too lightweight in bass, they may sound better closer to a wall. Remember not to block any bass ports. If the speaker is rear ported it needs a little space out from the wall and clearance on the sides of the speaker to perform properly.

One little tweak you might try: some speakers sound better with the speaker grills off. Try removing them and see if they sound better. In many cases there will be no noticeable difference, but it costs nothing to try.

Other issues:

If your speakers are correctly phased as described above but voices are not sharply locked in location you may have your speakers too far apart. This generally applies to stereo, not surround sound.

If not used on a surround system, the subwoofer crossover point should be adjusted to coincide with the drop off in bass from your main speakers. You may find this listed in your documentation, usually on the order of the -3db point. If your speakers still don't seem to perform like they should, you should consider whether the amplifier attached to them is up to the task of driving them. There are more issues here than power, especially impedance. An amplifier that has high wattage may drive 8 ohm speakers well, and do very poorly on 4 ohm speakers if the amplifier is not designed for "high current" or rated into 4 ohm speakers. In addition, many amplifier (or receiver, home theater amplifier, etc) manufacturers use various methods to exaggerate the wattage ratings on their amplifiers. The true rating to look for is called the RMS rating, and should be rated into a specific impedance (4 ohm, 8 ohm) etc and at a specific distortion rating. This does not imply that all amplifier & receiver manufacturers that use terms such as a 'Dynamic Power Rating' are trying to deceive consumers. In some instances (such as with NAD equipment) such figures can be very meaningful. Just make sure you are comparing apples with apples, and use the RMS rating as a baseline for comparison. If ALL other factors are equal, the one with a higher dynamic power rating can have more punch and impact.

Category 7 cable
Category 7 cable (Cat 7), (ISO/IEC 11801:2002 category 7/class F), is a cable standard for Ethernet and other interconnect technologies that can be made to be backwards compatible with traditional Cat 5 and Cat 6 Ethernet cable. Cat 7 features even more strict specifications for crosstalk and system noise than Cat 6. To achieve this, shielding has been added for individual wire pairs and the cable as a whole.
The Cat 7 cable standard has been created to allow 10 gigabit Ethernet over 100m of copper cabling (also, 10-Gbit/s Ethernet now is typically run on Cat 6a). The cable contains four twisted copper wire pairs, just like the earlier standards. Cat 7 can be terminated either with 8P8C compatible GG45 electrical connectors which incorporate the 8P8C standard or with TERA connectors. When combined with GG45 or TERA connectors, Cat 7 cable is rated for transmission frequencies of up to 600MHz.
Category 7a
Category 7a (or Augmented Category 7) operates at frequencies up to 1000 MHz, suitable for multiple applications in a single cable including 40 Gigabit Ethernet, 100 Gigabit Ethernet, and CATV (862 MHz). Simulation results have shown that 40 Gigabit Ethernet is possible at 50 meters and 100 Gigabit Ethernet is possible at 15 meters. Mohsen Kavehrad and researchers at Pennsylvania State University believe that either 32 nm or 22 nm circuits will allow for 100 Gigabit Ethernet at 100 meters.

From centuries we have been experiencing the changing life styles and this will go on changing because of the latest innovations and equipments which the manufacturers are giving us year by year for our comforts. Some of the products they have given us for our security are the concealed cameras, the spy cameras, the CCTV cameras and many other security cameras. The concealed cameras are the types of cameras which are very efficient and reliable. These are the products which are being used abundantly world wide these days for many purposes.

Well, as many of us are aware of the rising thefts and the rising mistreatments usually the baby sitters give the children while the parents are away from home. So in this case it had become very difficult for many working parents to leave the children with them and concentrate on the work. But again thanks to the latest innovations and the nanny cameras which can be used for the purpose of keeping an eye on the movements of the nanny or the baby sitter so that if any thing wrong happens then he/she could be fired from the job with complete evidence.

Although there are varieties of hidden cameras and the nanny cameras but the Hidden camera phone is very exclusive and resourceful when used for the surveillance and to keep an eye on the baby sitter because this unusual phone appears and works like the just other ordinary cell phone which is seen very often in many homes. The hidden camera phone is a perfect tool which can give relief too and therefore many working parents can easily afford to buy it because it has many features and advantages as well as with a reasonable price. Inside this cell phone a tiny but a technologically advanced spy camera is adjusted which has the efficiency to work up to 300 feet between the camera and the receiver. This shows that even if the hidden camera phone is kept anywhere in the room, the user can have the facility to view and listen to the clear and reliable video recording. The video recordings can be viewed clearly when the receiver is attached on any monitor or a Television set. If in any case the video cannot be viewed live, then one can record it on any VCR or the DVD player and watch them according to the requirement.

Saving Recollections on Video Properly

Many of us have old video recordings we'd like to remember as life events. They are on outdated cassettes and disks requiring noise reduction, brightness adjustment and recording compactly to 1 medium like DVD or Blu-Ray as a whole.

While 15-20 years ago such a task would be rather laborious, now it's well done with modern computer power. Latest video editor versions work miracles by improving image quality, for example, via a noise filter or enabling to adjust color, lay extra effects on video and use additional sound tracks like with comments or pleasant music. Here're some popular video editors with rich features to handle video and audio.

• Adobe Premiere Pro & Adobe Premiere Elements
• Ulead Video Studio & Ulead Media Studio
• Pinacle Studio
• Vegas Movie Studio

To this end, you'll need an installed video editor, enough hard disk space and a video capture board if you don't have previously recorded video like in AVI. If you did it before but the disk turned scratched, you'll have to copy it on the hard disk and then do AVI fix by using video editor features or a video fixer like Digital Video Repair or DivFix++.

Processing your recordings requires the following steps:

1. Record video with the best possible quality for subsequent processing if you haven't done this before. Use a Motion JPEG family video codec or the like.
2. Do initial edit by cutting out movie parts not planned for a final version. Use the cut operation to remove unwanted image pieces.
3. Set image brightness and contrast to make the picture more pleasant and improve subsequent video filter operation.
4. For images recorded from analog sources like VHS tapes, use a filter to do deinterlacing operation to remove the image comb effect.
5. In case of video noise, use a noise filter to improve its quality and compress an output file.
6. Resize a bit smaller to improve the result and output file size.
7. Lay necessary special effects to transfer from 1 plot to another.
8. If needed, add extra sound tracks with background music or comments.
9. Choose a video and audio compression format and record the result on the hard disk.
10. Burn the final video to an optical disk like DVD and make up its box.

For a better compression format, mind that if you want to show you movie to the friends from a stationary player, be careful in choosing audio and video codecs. Most contemporary video players support the AVI format with MPEG-4 (DivX, Xvid) compression unlike such computer formats as MP4, MKV, OGM and H.264 (upgraded MPEG-4) which provides far better compressed video quality with lower bitrates but fits few players. The most common audio codec is MP3 (MPEG Layer 3).

Pay special attention to choosing an optical disk for recording. For the longest life time, pick up a branded disk with an extra scratch-proof layer. If you have to transport the disk often, make sure the box is suitable fixating the disk tightly to prevent possible hit consequences when in motion.

Not to get lost in large disk collections, use cataloguer software and properly signed disk covers. So you can always find a necessary disk quickly and have other extra info without looking through all the recorded disks.

Approach preparing video creatively to get a quality result worth seeing in the family and showing to friends and acquaintances in your home.

Video Options From Spy Camcorders To Analog

There are many different types of camcorders to choose from, such as the micro spy camcorder or the HD camcorder. All of these camcorders have very specific features that make them more or less appropriate for certain tasks. Whether you are looking for an all analog video camcorder or searching for one of the new high definition digital models on the market, you will find that many options are available to you. Fortunately, it is easier than ever to comparison shop now that you can browse online. Spy camcorders have become some of the hottest camcorders on the market, and there are many styles to choose from. You can find a micro spy camcorder that is as small as a pen, for example, and pay as little as $80 for it. These spy camcorders are easier to use than any other video cameras on the market. They are designed to be just like point and shoot cameras, but for video rather than film, and they weigh only a few ounces so they fit right into your pocket just like a digital camera would. The better models on the market have good screen resolution, a small lens on one side with a viewfinder on the other side, and the high definition models shoot good enough video to watch on your television. You might think it would be hard to find a good analog video camcorder these days, but by shopping online you can really get a good deal and find a great selection. All analog camcorders can record video and audio data on different types of tape formats by converting electric signals from sound and using a machine to record light waves by writing their signal onto tapes. The quality of the images recorded on one of these cameras will differ varying on the recording format, however, such as VHS, VHS-C, Super VHS, Super VHS-C, 8mm or Hi-8. With so many camcorders to choose from, it's just a matter of selecting the one that's right for you.

LCD TV Installations

LCD Televisions generally used where you want a larger screen size and wider viewing area. The primary advantages of LCD televisions are their wider visible range and their ability to display accurate tonal ranges and true blacks. LCD TV which are the first in the world to come with a built in Blu-Ray drive. The 52, 46, 42 and 37" models will offer Full HD resolution whereas the 26 and 32 inches will offer 1,366×768 pixels.

LCD TV Installations displays, by contrast, utilize electric charges to twist and untwist liquid crystals, which causes them to block light and, hence, emit blacks. The higher the voltage passing through the liquid crystals in a given pixel, the more fully those crystals untwist and effectively block light all of which makes these pixels darker. You can throw away the DVR as the built in Blu-Ray recorder can record up to 21 hours of HD content on a double layer 50GB Blu-Ray disc. Other features include digital tuner, 1 bit amplifier which powers the bottom mounted speaker.

LCD displays consume the most power when displaying a very dark or black image. This is a difficult process, and despite recent improvements in LCD black levels, only the best LCD displays have managed to topple the 500:1 contrast ratio barrier. The one continual drawback here for LCD is off axis viewing, when black levels consistently drops. Yet, while many are aware of the susceptibility of plasmas to burn-in, few realize that even LCD TVs have their own problems they suffer from a phenomena known as image sticking.

All the Digital TVs that include LCD television or plasma TV differ depending up on how many pixels per inch make up the image, number of scan lines over the screen and the aspect ratio. The aspect ratio shows how wide is the screen in relation to its height. In early televisions and standard digital televisions the 4:3 is the aspect ratio is still followed which means the width will be slightly longer than the height of the screen.

LCD TV sets, screen burn-in are probably one of the most debated topics by those in favor of LCD display technology. Though image sticking and burn-in yields practically the same visual impact on the display panel, yet these two phenomena are completely different in their nature.

Audio Video Cables Installation

Cables and cords are essential to operating your favorite device. Component video separates the video signal into individual streams and these video streams are carried via three cables, colored red, and green and blue that normally comes bundled with RCA type jack connectors. Component video signals will provide better color resolution, purity and fidelity than S-Video and composite video signals.

For electronics like televisions, digital cameras and camcorders there are DVI cables, HDMI cables and S-video cables. Also, HDMI cables are used for content management. For example, a manufacturer would use it to enable service providers to control access to specific content.

DVI stands for Digital Video Interface, while HDMI stands for High-Definition Multimedia Interface. The biggest difference between DVI and HDMI is that DVI is used solely for video and HDMI cables carry both the video and audio signals through one signal. There are RCA cables, which are also known as composite cables, which include one connection for video which is usually yellow and it includes parts for left and right audio channels, which are usually white and red respectively.

Audio video Cables are higher quality analog video cables which are generally used in hooking up your television, VCR, DVD player, or similar to another video source, such as a computer. There are also component cables which are essentially providers of higher quality and better signal throughput.

The principle idea behind HDMI is the use of a single interconnects instead of several cables when connecting an audio video source, such as a set top box or DVD player and an audio and or video monitor, such as a plasma TV, over a single HDMI cable.

The use of a single HDMI cable that replaces the maze of cabling behind home entertainment centers is the primary advantage brought about by this new standard. This is not the case with DVI supports digital video only hence, a separate audio cable is needed to transport digital audio when a DVI cable is used.

Audio Video cables are used to hook up receivers, tuners, radios, stereos, micro shelf systems and speakers. Other cables that are also used in audio video equipment are optical cables which are used to transmit light as the signal and coaxial cables. For cords, some of most popular are actually wire harnesses which are used in cars to power a car stereo. For more details http://www.av-setup.com

Compression of Video and Audio Signals

Video compression

At present there are used a few compression methods. The oldest of them (JPEG, H-261, MPEG-2) use groups of pixels (covering some area, for example 8 bits x 8 bits). These methods don't analyze the actual structure of the image. This generation of compressors may be used in the case of lower resolutions when transmission speed isn't less than 64kbps.
More effective compression is offered by second generation of algorithms. These algorithms (e.g. MPEG-4) carry out a kind of scene analysis before realization of adequate compression procedure. They make out that image can be divided into fragments in more effective way. Image which consists of pixels with the same features can be divided into specific groups, and this operation significantly improves compression process. To achieve such analysis procedure, a model of human perceiving has been employed (HVS - Human Vision System) .
Typical second generation encoder consists of following modules: segmentation, motion estimation, outline and texture coding. The system offers compromise between compression rate and the quality of the image after decompression.

Video compression standards: H-261, H263

The H-261 system has been created for ISDN networks with 64 kbps bandwidth. The H-261 standard allows compression rates from 100:1 to 2000:1, however the higher compression ratio, the lower quality of decompressed image. The codec works in two modes: intra frame - INTRA and inter frame - INTER.

During the INTRA compression mode, the frame is being divided into blocks sized by 8x8 pixels. Then they are compressed using Discrete Cosines Transform (similar to JPEG).
In INTER mode, only changes which have been occurred between following frames are being saved. However, it has to be marked that at least once every 123 frames the compression in INTRA mode has to be carried out.
Development of H.263 standard has been meant to secure video signal compression for low bandwidth networks, about 28.8 to 33.6 kbps.
H-263 is a modernized version of the H-261 standard. In comparison with the original version, half-pixel motion compensation has been employed instead of pixel motion compensation. The header has been reduced, detection and transmission of error correction have been abandoned, and new optional modes of operation have been integrated.

MPEG-4 compression

MPEG-4 is the newest video compression standard which quickly becomes popular, also in the case of video streaming. In comparison with previously presented standards, it integrates effective methods for multimedia data.
New attitude consists in interrelation of data contents with the role for human perception, and extraction of so called audio-visual objects (AVO). There have been integrated solutions allowing scalability of data representation in many dimensions, that is space, time, quality and computational complexity.
The standard has been adjusted to many types of telecommunication networks and can operate at rates from 64 to 1024 kbps.
The concept of MPEG-4 allows transmission of single or several audiovisual AV objects from the sender to the receiver, however before the transmission begins, the initial exchange of information between the encoder and decoder has to be carried out. This way, the convenient algorithm classes and the tools essential for effective use of the link can be settled. Obviously, the coder protects audiovisual objects against errors.

Audio compression

Data stream from audio compression is significantly smaller than video data stream. However, the compression is normally performed to minimize the total bandwidth.
Simple reduction of link's bandwidth can be achieved by reduction of bit rate (sampling frequency) and reduction of amplitude resolution.

Depending on transmission type, various samplings are used:

Sampling frequency - Application

8.00 kHz - Telephony

16 kHz - Multimedia communication

22.05 kHz - Personal computers

32.00 kHz - Digital radio and television

44.10 kHz - CD - Audio

48.00 kHz - DAT cassette recorders, HDTV

96.00 kHz - DVD

Various Types Of Security Cameras Available For Your Use

It is helpful when buying a security camera to know the types of security cameras out there and to know how each one works. There are a wide variety of cameras out there for your use and for purchase.  Security cameras can be visible to the naked eye or can be hidden inside teddy bears, pens and other hidden objects that appear to be regular household items. Almost anything can be made from a household item and a hidden camera. This includes clocks and other appliances. If you use a clock, you replace number with a camera lens and voila, you have a camera clock. The video is recorded on its own without intervention from a security system.

Some cameras are stand-alone and go off of batteries, while others are hardwired into a main electrical system that also can take the camera image and put it on a video or computer screen. Standalone systems are those that have the video in the camera itself that must be removed before you can see what the camera saw.

A few hidden security cameras use regular SD memory cards that can be sent to your home computer in order to review the camera shots. The SD memory cards are removed from the camera after it has taken the video stream and the card is put into the computer in a special slot for SD memory cards. This prevents the owner from setting up and wiring a fancy security setup.

You can even wear a video camera discretely. They can be put into neckties, hats or any other easily replaceable item of clothing. You need to have a separate recording device that the person wears in order to catch the audio stream. You can find cameras small enough to record harassment at the workplace or theft in your home. You can hook up the camera to the internet so you can see what’s happening in your home even when you’re at the office. Nanny cams also do the same thing. You can hook up a small camera and have it linked to your computer so you can see what’s happening with your baby at all times on the computer. Whoever is being watched won’t even know they are being watched.

You can have a camera system that includes audio so you can see what is happening and hear what is happening all at the same time. Most people don’t need audio, however, so they just have a silent camera system or stand-alone camera that records the visuals of what you want to monitor but there is no audio associated with it.

They make dome cameras which operate in black and white and let you see a wide angle picture. An infrared camera is also possible, which records things seen in the dark or near darkness.  A bullet camera faces just one direction but is cheaper than a dome camera. You can get infrared cameras in a bullet or dome shaped mode. A C-mount camera allows for changing of the lens at any time. If you want a color camera, choose a C-mount camera that can allow for zoom lensing and good resolution, depending on the type of lens you choose. These are just a sampling of the types of cameras you can choose from.
