"The Original Copy of HubCam Detective Camera Still for a Good Price
The original copy of security camera with electrical movement from left to right and back. Camera moving is turned on automaticaly and it lasts aproximately 15 seconds whenever a movement is registered in front of the camera (movement sensor is installed in camera). During camera movement red LED is on. Thanks to elbow vertical angle can be regulated. Power supply two AA bateries, dimensions 135x5x55 mm (with objective, without handle).
You can install real working camera in this copy, also in our offer. In this way you can get functional good looking moving camera."
I believe this will help. As Maria wrote, it's an empty housing but it reacts to the movement.
