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


This video compares 720p HD video surveillance
footage captured by an AHD CCTV camera to a 960H resolution video captured by a standard
definition analog CCTV camera. This video was produced in 720p resolution, so I recommend
that you adjust the YouTube player to 720p and make this video full screen. You can do
this using the controls at the bottom of the player.
960H is the wide screen format used in modern analog CCTV cameras. 960H resolution is 960
pixels wide by 480 pixels tall. 720p resolution is supported by the new AHD CCTV cameras.
AHD stands for analog high definition and 720p resolution is 1280 by 720 pixels.
The new iDVR hybrid surveillance DVR support both AHD and SD CCTV cameras. I connected
two AHD cameras and two analog CCTV cameras to an iDVR-E4 model to make the following
video. Here’s a four camera view of all the cameras. The top two are the standard definition
CCTV cameras and the bottom are the high definition CCTV cameras, the AHD. We’re connected to
a 720p monitor and here’s what an analog CCTV camera looks like stretched out to a 720p
resolution and this is the HD camera that is actually 720p resolution, so it’s not stretch
out. You can see the difference in clarity. Again, there’s the 960H and here is the AHD.
Here’s the other 960H CCTV camera, again, stretched out to 720p and the AHD, high definition,
which doesn’t require any stretching because it’s natively 720p resolution.
