One that does not achieve much. I wish more people selling CCTV could promote the fundamentals of what a camera is used for. Starting at 4CIF the person need to occupy the below % of the scene height for the following. If you double the resolution, halve the % Identify an unknown person 100% Recognise a known person 50% Detect what a person is doing 10% Observe is a person is in an area 5% You can see examples here. http://cctvdesign.com.au/surveillance-camera-comparison-parameters My frustration with many CCTV system designs is people do not know what they want to achieve and as a result get a result that meets there level of knowledge.

When i switch to channel 1 in full screen mode, i can see in the background the live of channel 4, and in channel 4 in the background, i can see the live of channel 1, rest all the channels are perfect and quality is good. I have checked these two cameras on the other DVR, it has no problem. I tried to plug these two cameras into differnt channels as i have 4 channel still to be occupied, now they are interfering into the channels. What could be causing this interference. Anticipating your quick help on this. Hi,
