bullpup....at least that's what I use. Aside from that you guys can do like I have on my garage and get a camera. You can get a 2 inch tall camera from BOSS for $50, it is color and you can set it up with hardwires or remotely. Then just mount it somewhere and leave a monitor on with a vcr recording. The whole setup ran me about $200...but the peace of mind makes it well worth it.
