Getting to Know the BirdCam
Photocell
The BirdCam is equipped with a light-sensitive, photo-cell which con-
stantly measures available light. In very low light, the photo-cell forces
the BirdCam into NIGHT mode. This conserves battery power when
there is not enough light to take pictures. When the light level increases,
the photo-cell will 'wake-up' the BirdCam, which will resume operations
according to current settings.
