Improving the Video Security DVR can be done through the technological advancement in video compression called H.264 Technology. This type of compression technology delivers high video quality and excellent compression ratio. Many companies are already implementing the H.264 technology and incorporating it to their products especially in security cameras due to its superb performance. These companies involve Apple, Intel, Sony and its product Blu-ray and Direct TV and Dish Network (Satellite Providers) are just some who have joined.

Specifically related to security DVRs, here is how H.264 technology benefits you:

Extended Record Time – Because H.264 technology compresses data into smaller sizes such that it can be stored effectively producing superb compressing capability, recording periods may be doubled or longer than most of the previous compression methods and in security cameras. Using the same size of hard drive, you can record video longer, thus ,saving money and resources. This can also increase the videos being stored for evidence form digital video recorders and security cameras, digital surveillance systems and video surveillance systems. H.264 can compress video data with 720 x 480 resolution which is 30 fps into a 160GB in 77 hours of record and play time. MPEG 4 can only compress in 44 hours and the JPEG2000 which can only do- hours.

Does not compromise the quality and speed – The compression techniques of the previous technologies allows the recording of seamless and excellent picture quality on digital video recorders, video surveillance systems at real-time frames rates however, it eats up too much space in hard drives wasting valuable bytes. In H.264, compressing the videos captured by security cameras and digital video surveillance systems will be considerably reduced through the use of predictive technology. This method reduces the amount of unneeded videos recorded on security DVR. Unlike from its previous predecessors where it records continuously the entire time, H.264 samples up to 32 frames of video and uses the prerecorded background if no motion is detected. Other compression uses only 1 to 2 frames in basing their background image.

Improved remote monitoring – Saving hard drive space is not the only benefit of H.264. The ability to bring together high quality and low memory sizes allows for seamless presentations of video when transmitted. Coupled with low frame rate recordings, previous compressions made watching video from remote video security DVR units a trying experience – especially when activities in question happened fast. Video would be jumpy, and audio (if used) wasn’t likely to be synchronized with the video. Watching real-time H.264 is a completely different experience, and the reason so many broadcast companies around the globe have rapidly adopted 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 improve your surveillance final results by offering options in video and audio. Security DVRs are recognized useful instruments.
