When YouTube user mrfid72 discovered evidence of a little critter occupying his shed, he did what every maker would do and set up a Pi camera to catch all their nocturnal antics.

Using four ultrasonic units to create a barrier around his rat trap, Mr. Fid set his Pi to take a high-resolution, timestamped photo alongside two minutes of HD video whenever the distance between the units was shortened by a furry obstruction. The Pi also turned on an infrared light to better catch the action.

Images are then emailed directly to a predetermined address, while all footage is uploaded to a web page via FTP, allowing Mr. Fid to check up on any prerecorded action in the shed whenever he wishes, providing he has internet connectivity.

He continued to record the mouse over several nights, each day reviewing the footage to understand how the mouse was foiling his trap to obtain the delicious treats within.

Follow the action via the video below, right to the end where OMGIT’SSOCUTEANDFLUFFY!

Raspberry pi infared Mouse Cam. Raspberry pi infrared mouse camera. using 4 ultrasonic units to measure the distance around a rat trap, as soon as the distance is shorten by an obstruction then the raspberry pi firstly turns on the IR light source, then takes a low resolution time stamped photo, then a big picture followed by two minuted of hd video.

If you wish to build your own Mouse Camera, the wonderful Mr. Fid has made the build available via Instructables. Thanks, Mr. Fid!
