2006 Season
Box 1 Camera for 2007
Season
Box 2
Camera The camera, in
nest box 1, is an
Axis 2100,
network camera. The standard, 4mm, lens was replaced with a 2.8mm, wide angle
lens. Lighting is by means of 3 white LEDs. These were only turned on during
the day or to take a snapshot at night. The Axis camera sets its exposure time
to suit the ambient light level. There are times when the exposure will be
quite long and any movement will result in a blurred image.
The image was uploaded, by FTP,
to the web server. Initially the image was refreshed every 15 minutes during
the daytime. The rate was increased to once every 10 seconds, when there was a
lot of activity.
Stills were stores directly
from the 2100. Video was captured using
VLC player, for high
rate video, or
iCatcher, for low rate..
