HD CCTV Camera (720p AHD) vs SD CCTV Camera (960H) Video Surveillance

http://cctvcamerapros.com/AHD - This is a comparison of the video surveillance resolution of AHD HD CCTV cameras vs analog CCTV cameras. The resolution of the AHD security cameras is 720p which is 1280 by 720 pixels. The resolution of the analog CCTV cameras is 960H which is 960 x 480. Here is how the test was performed. We connected 2 of each camera type to an iDVR-E4 hybrid video surveillance recorder. This hybrid DVR is compatible with both AHD and 960H format cameras. The DVR was connected to a 720p monitor and a video capture card so that we could capture the video. The capture card was also capturing the video at 720p HD resolution. During the video, when each camera is shown full screen, it is at 720p resolution. So, the 960H video from the analog CCTV cameras is stretched from 960 x 480 to 1280 x 720. Because the HD security cameras are natively 720p resolution, they are not stretched. Although the 960H CCTV cameras do capture a nice clear video, you can easily recognize a difference in video clarity between the two technologies. The hybrid iDVR recorder used in the video is an excellent choice for people that have existing CCTV cameras in place and want to add a few HDcctv cameras now or in the future.
