My buddy has a non-typ camera and I works great. If you check out my webpage, you can see a lot of the pictures taken off of my property.

It has a pir sensor which needs a change of temperature in motion to set it off. I believe it has 4 setting for the timers in basic mode and up to 7 or 8 in advanced. When in basic mode the camera is almost fool proof. As long as you open the camera and have the batteries pluged in it will work. If you leave it in test mode it will switch to auto after 4 minutes. One of the only downfalls is in the battery life. The 9 volts don't last the longest. They are good for a couple of rolls of film in the harsh conditions. I believe this can be fixed with NiMh rechargeable batteries. They double the life of regular batteries in digital cameras, so I believe they would make a great difference in this unit. Personally if I was buying one, I would get one of these. Best bang for the buck. Now if money grew on trees, I would probably get a digital Cam Tracker.
Here are a few picts.
