I've been deploying a few of cheap consumer trail cameras near where I work since about March 2014. I started doing so when I was attempting to administer medication to a Fox with a bad case of Sarcoptic Mange so that I would know if the fox had taken the medicated food.
Since then I've been monitoring the local wildlife and it's inspired me to begin building a DSLR camera trap system.
The adjacent slide show contains some of the images from my home built DSLR camtrap, the rest are taken by the consumer trailcams.
I'll put together some basic information on the DSLR setup which can be accessed from the CamTrap menu, you can also read a blog post which highlights some of my experience in building and using a homemade DSLR camera trap
