Patent attributes
An alarm and security system is incorporated with a screen unit that may be a part of a window or a part of a patio door or the like. The screen unit is formed of robust expanded metal mesh to discourage intrusion therethrough. A plurality of locks about the frame of the screen unit lock the screen unit with a supporting frame. A control unit is coupled with sensors for sensing motion of the screen unit or tampering with the screen unit to activate audible, inaudible and/or visible alarms at a local or remote location. A camera, activated by the sensors provides an image upon tampering or intrusion of the screen unit. If the screen unit is a screen door, a pet door in the screen door is locked in place to prevent intrusion but a signal generating element on a pet will release the lock when the pet is in close proximity. A remote receiver may be used to receive an alarm signal from the control unit.
