After many trials and tribulations I managed to set up a temporary recorder to catch any action last night. I put out some crushed unsalted peanuts in case the Hedgehog went walkabout. The recorder managed to capture one reasonable piece of video.
Looks like I had better give the camera a wash and brush up as it has been out in all weathers over the winter. In case you are wondering the clip starts with a still frame from the video. Also I need to re-route the cables so I can use my normal recorder as it is easier to operate.
