As image is produced, IR cut filter is positioned over the imager In order for color security cameras to accurately create colors. The cut filter permits the camera to only see light in the visible spectrum (400nm to 750nm). As a result, color surveillance cameras fails when it comes to creating important images in not so lighted scenes.
Conversely, black and white video camera surveillance setups don’t use an IR cut filter because they do not need to see color. With the absence of this filter, B…W CCTV camera options can make use of other light frequencies – such as infrared – which come from a variety of sources, including the sun, fluorescent lights, incandescent lights and of course… infrared illuminators. As a result, B…W surveillance cameras perform significantly better in low light and some can see at light levels as low as 0.0001 lux (almost complete darkness). An additional benefit of B…W video surveillance cameras seeing in the infrared range is the ability to illuminate an area with IR, providing the camera with ample lighting while leaving the area naturally dark which can aide in the capture of suspects.
More about Day/Night Cameras Can give
Day/Night security cameras offer the unique advantages of both color and black and white CCTV camera setups. D/N video security cameras work just like color cameras during the day and switch to a B…W mode at night, using a removable IR cut filter. As daylight fades, day/night cameras sense the lower light levels and mechanically remove the IR cut filter, instantly switching to a more sensitive black and white mode.
Day/night surveillance cameras are offered in all forms to get the satisfaction needed in every establishment or home.Effective undercover operations gadgets like dome cameras, fixed cameras, bullet cameras and even in tiny board cameras are presented in many D/N technology forms.

3. S/N Ratio – Numerous surveillance cameras in the marketplace with low lux ratings, however it does not automatically mean they will produce a high-quality picture in low light. To make sure you get both, choose a security camera with a signal-to-noise ratio of 48dB or higher.
