probably good advice really, hard wiring to a permanent power source is not advisable for cameras with internal batteries, and the motion detect doesn't work very well on these and you'd find if you left it on all the time you'd miss things when it really should be recording, wrong product for this usage scenario
Now that I have two of them, is there a decent camera to use just for motion detection as I keep getting the car scratched by idiots, nothing seriously deep but enough to need polishing out.
