Recently, I was asked, “Can Video Security DVR get any better?” Absolutely, and they have! The latest advancements in H.264 compression technology for your security DVRs now deliver the best of both worlds – high quality video and a superb compression ratio. In fact, H.264 compression technology works so well, that many big companies are quickly implementing H.264 technology, including Apple, Intel, Blu-ray, Sony and even Satellite providers such as Direct TV and Dish Network.
The benefits of H.264 technology and its contribution to security DVR and security cameras:
Longer record times – As mentioned earlier, H.264 provides superb compression, in most cases more than doubling record times over previously popular compression methods. The advantages of H.264 are impressive! The ability to record longer periods of time on the same sized hard drive will save you money, and greatly increase the amount of video evidence you can archive from your digital video recorder. When recording video on a 160GB hard drive at 30 frames per second with 720 x 480 resolution, H.264 compression produces around 77 hours of recording time. MPEG4 and JPEG2000 compressions only produce 44 and- hours, respectively.
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.
Enhanced remote monitoring – With high quality and low memory size, H.264 produces flawless video presentations. This also makes it easy to network your devices and monitor them from distance. Previous compressions are not accurate especially when they are capturing fast movements; this is due to its combination with low frame rate recordings. Watching video security DVR and digital video surveillance then is not a pretty site: the videos are bit jumpy and the audio is not synchronized with the video.
Cautionary Advise – H.264 compression has the potential to dominate the video industry in the future and be widely used by the public. Find the right producers of such products to ensure you get the maximum benefit it provides. Go with the makers with proven track records and trusted throughout the years. H.264 is definitely great for security cameras, digital video surveillance systems.
