The Securitcam M1000 simulated surveillance camera is a very easy to use security system. Every time you detect movement (approx. 5m), the red LED will start flashing for about 20 seconds, giving the feeling that it is active and connected. It does not detect motion in the dark, but it does activate when a dark place lights up. It has daytime motion sensor. Requires 2 x AAA batteries (not included). Dimensions (with stand): 18 x 13 x 7 cm. Includes 2 dowels and 2 screws for fixing to the wall.
