Are you likely to switch to a digital CCTV system but worried about the cost of movie storage? This is a suggestion on a compression format that can help you conserve disk space without compromising video quality.
In the first days of CCTV technology there is no need much option but to choose an analog DVR to record monitoring information. The movie quality was not good. Someone have to be around to alter the video record when it works out if saving place. It's made the move to digital technology an attractive solution. Although it would have not triggered a novice much frustration to purchase an analog CCTV system, selecting a digital one could be fairly challenging.
As your surveillance camera is anticipated to run 24\/7, there'll be considered a large amount of video information that really needs to be documented. The obvious problem is how you'll be managing the storage of the information. example here. Would you need to pay a huge sum of money for data-storage? You'll wonder whether you'll have sufficient hard-disk space to store your video info. Your worry is justified as an hour of uncompressed video at an answer of 320 x 240 will take up about 21GB of place.
Uncompressed movie of course provides you with perfect quality. However, when it comes to CCTV video, content rather than quality requires preference. Nobody wants to sacrifice a substantial number of disk space for the cause of graphic quality.
Pressure Formats:
Will there be an easy method of reducing disk usage for your CCTV video without sacrificing quality? There's if you are using a proper compression format. Among the compression models available for CCTV compression are MJPEG, MPEG and Wavelet, which really is a proprietary compression format not in popular use.
MJPEG or Motion JPEG is a lossless compression format which produces data from the series of JPEG images. While quality is high, it needs a substantial number of space for storage.
MPEG on another hand is available in two compression types. MPEG1 is really a low-quality compression format which outputs movie at about 15 frames-per second. MPEG 2, on the other hand guarantees high quality video but uses up much space for storing. There are particular hardware specifications for MPEG 2 which can not be offered by your PERSONAL COMPUTER.
Mpeg-4 Part 2 (MP4) employed by these codecs as Divx and Xvid can be common. This assures better-quality than MPEG 1 and less space for storing than MPEG 2.
MP4 was previously a popular CCTV retention structure before the introduction of H264 or also known as AVC (Advanced Video Coding). Impressive video quality is promised by H264 compression despite a significant lowering of video file size.
It has a file size 80 % smaller than MJPEG compression. What is more it takes up 50 % less space for storage compared to MP4 pressure. Hence through the use of the compression, CCTV users could save on hard disk storage while enjoying fantastic video quality. In the event the H264 compression is used thus, in the place of receiving only 1 hour of uncompressed video for a space of 21GB, you will get as much as 80 hours of video.
If youare in the market for a DVR for your CCTV system, ensure that it facilitates H264 pressure so that you may save very well storage space without compromising video quality.s
