Choosing between color and black & white footage isn’t very common anymore as some impressive technology has come on the market. But it is important to make sure the cameras you choose provide features that will allow you monitoring during the night and darkness as well as during the day. The best cameras will be able to detect when the lighting has gotten low and can switch over to infrared or “night-vision” filming. This will ensure no matter what time of day it is your home is protected.
