so this thread did inspire me to go check out some trailcam prices
the good ones seem to run around the $500 point
there are cheap ones that start around $50, from my quick read on the reviews the cheap ones are more likely to get false triggers, and shoot lots of pics
for myself, i know i would want 2 to feel safe, want the redundancy and a couple of view points
snap in a cheap cell phone, and you could have quite the monitoring station, but not sure how tough it would be to get a cell phone to pull in the pics and post to a gmail account(encrypted pics preferably)
