Infrared / Night Vision Camera
However, black and white video is always better than no video, and the main purpose of infrared cameras and IR technology is to see in total darkness. In some CCTV systems, you cannot take the risk of not being able to see with color cameras in low to no light conditions. Some color video cameras can work in low lighting conditions, but they are on the more expensive end and still can't record in total darkness like an infrared camera. You do not want to invest over a grand in security cameras, cables, and a Security DVR and still have no video surveillance footage.
It is very important to not use infrared cameras with 12 or more IR lights indoors, as the IR light can bounce off of objects and wash out the image. Most indoor CCTV applications have tight/small rooms and reflective surfaces, such as windows, doors, coffee tables, fish tanks, or anything else glossy. This is really important advice for homeowners who are consideringindoor infrared cameras, as many glossy interior paints will reflect infrared light.
You do not want to go overboard with infrared technology; get something simple. In most cases if you have a hallway night light or (if you want to invest in them) auto-night lights in every room of the house you will have enough light to have a color picture indoors. An infrared camera can be very valuable (especially if the person you are trying to capture is disabling your lights), but you don't want to think of an infrared camera as anything more than a backup device.
IR stands for infrared radiation. IR is electromagnetic radiation at a wavelength that is longer than that of visible light, but shorter than that of terahertz radiation and microwaves. This means that you can't see it, but it still won't cook you. IR is a byproduct of heat.
Infrared cameras mathematically convert IR into the visible spectrum, which is why you can only see in black and white in the night. The technology in an infrared camera is a lot more common than people realize; IR technology powers such items as night vision goggles, heat seeking missiles, your television remote control, the mouse and keyboard you are using to surf this website, and many telephones.
