amememba pointed out he used: ...camera is equipped with a flash and the motion detector snaps the shot. I activated the camera at the break of dark.
other camera's just take a 'snapshot' every 10 to 15 seconds, others still work on other methods, --some are sound rather motion activated.
motion detectors have gotten really cheap --they are commonly used on exterior lights (i used to have them on my front door) and in ladies rooms and store rooms, the lights come on when the door is opened, and go off X miniutes after they stop detecting motion.
but they are hard to calibrate. my exterior door lights detected motion in the street as well as on the sidewalk.. so passing cars could activate the lights. --fortunately, my house was on a dead end street. i am seriously thinking of getting a motion activation switch for my entry hall in the apartment.. i like coming into a lit house/room, i hate leaving a light burning all day!
