3-Pc. Motion-Activated Security System

You get two sensors that each operate independently; when motion is detected within 5', it will sound an alarm for 5 seconds. Gives you a 5-second exit delay after you activate it. You also get a simulated security video camera that has a flashing red LED light, and actually "pans" side to side, to help deter potential intruders. Sensors and camera each have an on/off switch, and require three AA batteries (nine in total; none included). Sensors are each 3"x3-1/4" tall; extend 2-1/4" from wall. Camera with adjustable bracket is 2-1/4"x6"x6-1/4" tall. Mounting hardware included.
