I live on a farm, miles from the nearest town and neighbors. My place has been hit a couple of times, quick grab and go scoundrels and not much more. I purchased 6 of these to place around our property and I used lithium batteries, not the cheaper types that you might install in a flashlight.
The lithium batteries power a small red LED light that blinks on and off and give the impression the cameras are "on" and "seeing" what might be in their view. The LEDs have been blinking reliably for a month straight and at night they look VERY real.
I'm impressed with this device because they resemble true cameras that emit an invisible infrared light for night viewing. They have held up well in storms and are easy to adjust and rotate. If someone looks close at the front of the camera, it appears to have built in infrared illuminators. These are the new technology "lights" that provide an invisible light that the eye can not see, but a professional crook might understand and know is the same style of light used on expensive "game cameras" that hunters use to capture images of animals at night.
I'm happy with my purchase and I feel these "fake" cameras do a good job to discourage thieves.
(UPDATE... NOVEMBER 2013. These "cameras" are still working well and in the 2 years since I wrote this review, I have not had any crooks steal anything from me.
Some points... * Lithium batteries. Sometimes they will run the camera for 3 weeks and sometimes they run 5 weeks. I surmise this might have something to do with cold or hot season. * Some discussions here stating "no wires" and my thoughts are "no big deal" because WiFi cameras look a lot like this and, cameras placed around by deer hunters have no wires, because the have SD cards that can record video.
Bottom line... in two years, I have not had a failure in anyone of the 6 "cameras" I bought, and the little red blinking LED light is easy to see at night. They have been sitting outside, unprotected and have been rained on, snowed on, have stayed out in the Texas sun (it was 111 degrees here one summer) and they haven't missed a beat.
