Nest box camera

A nest box camera, also known as a bird box camera, is a device for monitoring birds in nest boxes. Many pictures and videos of nesting birds can be watched on Internet sites that broadcast video streams and still images in real time.
==Technology==
As well as using visible light, infrared cameras may also be used since infrared light is not dangerous to nesting birds. The camera which is used is usually a webcam although newer technologies allow network cameras in high-definition video. Some of the nest box cameras also have microphones inside them. It is relatively easy to construct a nest box camera because often it involves little more than installing a camera in a nest box, remembering only to choose or construct a nest box large enough to contain the camera, to have a box deep enough to enable proper focusing of the camera and to use a camera suitable for outdoor conditions.
