Technical
bit for the technically minded from Mark:-
I used a Maplins
infra red camera. Part number MS37S. This produced
an interlaced TV image at 480 x 576. This fed
a VHS machine, which in turn fed
the living room TV set. The RF output of the VHS recorder was distributed to the
PC (in a separate
room). I installed a Pinnacle
Rave TV card. This processed the images and uploaded them
to a Web Cam utility from
Pysoft. This ftp uploaded
to the web space a new
image every 10 seconds.
In 2007 I bought a new PC, I could not make the Pysoft software work with any stability.
Therefore from April 2007 a new application from Kabcam has been used.
The images seen on the previous pages were also produced by a frame grab and processing option within the Pysoft and Kabcam applications.
Illumination inside the box was provided by 6 IR LEDs mounted on the camera's PCB.
The whole
camera assembly including the lens measures 57x38mm and is 27mm deep. It is
mounted above a perspex ceiling inside the box. The
entry hole for the birds is at the bottom
of the pictures.
