A timely question to all digital video surveillance system users is whether video security DVR can have innovative versions? The answer is very simple and clear; of course, it will have better versions and innovation features. It is now possible to both high quality video and an excellent compression ratio and this is the most recent upgrade in H.264 compression technology. Actually, H.264 compression technology performs superior which made countless multinational companies are promptly applying H.264 technology, such as Apple, Intel, Blu-ray, Sony and even Satellite manufacturers like Direct TV and Dish Network.
Purposely connected to security DVRs, here are some facts that how H.264 technology gives you advantages:
Longer record times – As discussed previously, H.264 offers excellent compression, mostly more than twice the record compared to well-recognized compression techniques. The benefits of H.264 are remarkable. The facility to capture longer periods of time on the same hard drive size will save you funds and significantly boost the quantity of video data you can store from your digital video recorder. In recording video on a 160GB hard drive at 30 frames per second with 720 x 480 resolution, H.264 compression makes around 77 hours of recording time. MPEG4 and JPEG2000 compressions only generate 44 and- hours, correspondingly.
Quality and speed does not suffer – Previous compression methods have always allowed you to record excellent picture quality on your digital video recorder at real-time frame rates – but you were eating up valuable hard drive space. Similar to MPEG4, H.264 compression uses predictive technology to drastically reduce the amount of redundant video recorded on your security DVR. In simple terms, instead of constantly recording say a room with no motion, H.264 will use previously recordings images. However, if someone walks into the room, H.264 will record that person and continue to use the previously recorded background. H.264 will sample up to 32 frames of video to ensure complete accuracy and quality – whereas other compression methods would use only 1 or 2 frames as a reference.
Superior remote monitoring – Storing hard drive space is not the only advantage of H.264. The facility to bring together high quality and low memory sizes allows for flawless presentation of video when transmitted. Coupled with low frame rate recordings, previous compressions made surveilling video from remote video security DVR units a trying experience – especially when activities in question happened fast. Video would be unstable, and audio (if used) wasn’t likely to be harmonized with the video. Surveilling real-time H.264 is a totally diverse experience, and the cause numerous broadcast companies around the globe have fast used it.
A word of caution – Although H.264 compression is without question a giant leap in video technology for all industries, but just having that feature in a digital video recorder does not mean that it’s a good DVR. To make all the magic happen, it takes more processing horsepower. So be sure to use a manufacturer with a proven track record, who stands behind their products, and one who will be there for you should you need a hand.
Digital video recorder can enhance your surveillance final results by supplying options in video and audio. Security DVRs are considered popular tools.
