Night Vision Spy Cameras
Night vision hidden cameras and spy cameras are becoming more popular because they allow you to see what's going on in your home or office - even at night, or if the lights go out. Night vision nanny cameras work by using an infrared or "IR" sensor that allows the camera to see in areas that normal human eyes cannot. The video image is in black and white, as the IR sensors allow the camera to capture image information not available to non-night vision cameras. This makes them a very useful tool when you want to know what's happening, but the lights are low or turned off.
