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.
