Abstract
A junction box mounted infrared motion detector is set forth. It incorporates push button controls mounted on a box which has a Fresnel lens looking into the immediate vicinity and which encloses an infrared detector to sense an intruder. An ambient light photocell responsive to visible light is also included to enable the device to be switched off in the daytime and on at nighttime. The circuit controls a remotely powered lamp or other alarm device. The electrical current to the lamp is adjustable by means of a slide control.
