ever since i identified the thieves, i'm no longer interested in a picture of who stole my plants. i just want to keep it from happening.
my next deterrent is to mount a plain old box (built from scrap for $0) with a red LED visible from the outside ($0, i have batteries, LED lights and all the rest lying around) and a false wire that looks like a plug leading into the greenhouse (again, free) along with a motion sensitive light ($15?) and a sign my friend will make ( for a few grams of treadmills) that says "video surveillance" or something like that.
surveillance is completely worthless IMO, it is very expensive and easily beaten by a $3 ski mask. my deterrents are many: 6 foot fences, an 8' electric fence with signage, motion sensor alarms, door alarms, boarded up like a fucker, and soon to have chicken wire across the inside. not to mention 24/7 monitoring by humans. i sleep out there and the neighbor watches the house from our backyard when the wife and i go out.
