Our eyes can see and recall things better if they appear in color - it’s
easier to track down a blond-haired person wearing a green sweater
and black jeans than a dark, grey-black figure that would be produced
in a black and White camera
Color security cameras carry an additional premium in price compared
with black and white cameras. But they are also less sensitive to light
and makes it an impractical option unless good lighting is available.
Black and white B/W security cameras have better resolution and clear
pictures in low light conditions. All infrared security cameras turn to
black and white during low light conditions and résumé to color in good
light conditions. This can be particularly useful where planning
permission makes extra lighting impractical or the security requirement
is such that intruders should not be alerted to the existence of CCTV
surveillance.
Day and night cameras are a fairly new technology. These types of
cameras can operate in full color and have a sensor that switches to
black and white camera when the light condition is lower than 1.5 lux
