If you don't want the camera damaged or stolen you will need to put it in an inconspicuous location. If you can find a spot like that high in a tree, all the better. However, I would try to put it in a spot where people don't typically look, even if it is in the tree.
I have purchased five trail cameras over the past year (2 Wildgame Innovations IR4, 2 Moultrie M-80 and a Bushnell Trophy Cam with the blacked out top portion). The BTC is the best of the lot, IMHO.
My needs may be a bit different than yours but I needed a camera that would cover a very large area where I knew thieves had entered. I wanted to be able to get their picture from a distance at which the sensor would not have been tripped. Both the BTC and the M-80 has the plot-watcher feature. Essentially, you program the camera to take pictures at certain intervals (every 1 minute, 5 minutes, etc) during specified times. However, there are two big differences between the two cameras when utilizing this mode.
The BTC allows the user to program it to take pictures for a 24 hour period. The Moultrie will only take pictures in this mode from just before daylight to just after sunset. (The M-80 has a Hybrid mode which will take pictures at intervals throughout the day and whenever the sensor is tripped at night) The BTC will take pictures whenever the sensor is tripped, in addition to the scheduled time slot. The M-80 will not. Finally, the quality of the pictures taken during plot mode are different for each camera.
The M-80 seems to take a much lower quality image during the plot mode than it does normally. It does have software that comes with the camera allowing the user to stitch all of the pictures together that may be watched at 1-4x speed (or is it up to 5x? can't recall). Anyway, the BTC pictures are of a much higher quality but unless you load them into a slideshow, you have to hit the mouse or keyboard whenever you forward to the next picture. This small inconvenience is worth the extra picture quality, especially given the situation.
One final note: I have used all these cameras with only the Wildgame Innovations external battery pack. This pack is about $50 up front but the batteries 1) last much, much longer and 2) are rechargeable. I left the two WGI cameras out a good part of a very cold winter last year; the batteries were still showing nearly a full charge when I took them down (2-3 months later).
Here is a link to a few pictures taken by my BTC. I'm not sure if these are of the same quality as the pics that were uploaded to my pc or not (they went through photobucket and I can't remember if they were dumbed down a bit before I posted them or not).
