The programme was commissioned to study the psychology of cats and was made on location at a farm in Scotland.
The filming of wild cats required “cat cam” cameras to be set up and left unattended for many hours. With only one hour of filming time available on the cameras, a system was required to turn the cameras on only when cats were present. An infrared beam detector was used at the entrance to a barn which, when triggered by a cat entering the doorway, activated the camera using easyRadio modules.
A wireless solution, the eRA400TRS module, was chosen. The locations of both camera and detector were difficult to access and were a great distance apart; running a cable around the barn would have been difficult and would have had health and safety issues.
The designer of the TV company comments,
”I have had experience of using LPRS’ easyRadio in the past and I knew straight away it would be the answer to this problem. I just needed to write some software to control the VTR and the protocol for the easyRadio interface to the micro-controller was really simple.”
