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. ## Claims ### Claim 1 A secure screen unit mounted within a supporting frame for preventing unauthorized tampering and intrusion, said screen unit comprising in combination: a) a robust metal mesh having a perimeter; b) a metal frame engaging the perimeter of said mesh for supporting and for preventing relative movement between said metal frame and said mesh, the robust metal mesh and the metal frame together forming the screen unit; c) at least one locking device mounted on said metal frame for securing said screen unit with the supported frame; d) at least one sensor for providing a signal indicative of movement of said screen unit or tampering with said screen unit; and e) a control unit mounted to the screen unit, the control unit accessible at the screen unit for directly activating and deactivating the at least one sensor and for providing an alarm upon receipt of a signal from the at least one sensor. ### Claim 2 (depends on 1) The screen unit as set forth in claim 1, wherein said screen unit is a screen door and including a pet door formed in said screen door, said pet door including a lock for preventing opening of said pet door, a signal generating element carried by a pet for unlocking said lock and a sensor for sensing the generated signal when the pet is in proximity to said pet door. ### Claim 3 (depends on 2) The screen unit as set forth in claim 2 wherein said lock is coupled with said control unit to generate an alarm upon unauthorized movement of said pet door. ### Claim 4 (depends on 2) The screen unit as set forth in claim 2 wherein said pet door is hingedly attached to said screen door. ### Claim 5 (depends on 2) The screen unit as set forth in claim 2, including an insect screen, said insect screen including an opening sized commensurate with a pet door formed in said screen door. ### Claim 6 (depends on 1) The screen unit as set forth in claim 1, including a receiver for receiving a signal from said control unit upon generation of a signal from said control unit. ### Claim 7 (depends on 6) The screen unit as set forth in claim 6 wherein said receiver may be carried by a person. ### Claim 8 (depends on 1) The screen unit as set forth in claim 1, including an insect screen detachably attached to said screen unit to prevent intrusion of insects. ### Claim 9 (depends on 8) The screen unit as set forth in claim 8 wherein said insect screen is magnetically attached to said screen unit. ### Claim 10 (depends on 9) The screen unit as set forth in claim 9 wherein said insect screen includes magnetic elements disposed on a border magnetically responsive to said metal frame of said screen unit. ### Claim 11 (depends on 9) The screen unit as set forth in claim 9 wherein said insect screen includes a border for supporting a plurality of magnets magnetically responsive to corresponding sections on said metal frame. ### Claim 12 (depends on 1) The screen unit as set forth in claim 1, including a camera responsive to a signal from said control unit to obtain an image of an unauthorized intruder and of a person tampering with said screen unit. ### Claim 13 (depends on 1) The screen unit as set forth in claim 1, including an audible alarm responsive to a signal from said control unit. ### Claim 14 (depends on 1) The screen unit as set forth in claim 1, including a telephone connection to a location for summoning assistance in response to a signal from said control unit. ### Claim 15 (depends on 1) The screen unit as set forth in claim 1 wherein said signal generating element is an RF transmitter. ### Claim 16 (depends on 1) The screen unit as set forth in claim 1 wherein said signal generating element generates an inaudible signal. ### Claim 17 (depends on 1) The screen unit as set forth in claim 1 wherein said signal generating element generates a signal in the IR frequency range. ### Claim 18 (depends on 1) The screen unit as set forth in claim 1 wherein at least one of said locking devices is disposed at the top and bottom of said metal frame. ### Claim 19 (depends on 18) The screen unit as set forth in claim 18 wherein at least one of said locking devices is disposed on a side of said metal frame. ### Claim 20 (depends on 1) The screen unit as set forth in claim 1, wherein said screen unit is a screen door and including a pair of said screen doors mounted as French doors within a door frame. ### Claim 21 (depends on 1) The screen unit as set forth in claim 1 wherein said screen unit is a window. ### Claim 22 (depends on 21) The screen unit as set forth in claim 21, including a camera responsive to a signal from said control unit to obtain an image of an unauthorized intruder and of a person tampering with said screen unit. ### Claim 23 (depends on 21) The screen unit as set forth in claim 21, including an audible alarm responsive to a signal from said control unit. ### Claim 24 (depends on 21) The screen unit as set forth in claim 21, including a telephone connection to a location for summoning assistance in response to a signal from said control unit. ### Claim 25 (depends on 21) The screen unit as set forth in claim 21 wherein said signal generating element is an RF transmitter. ### Claim 26 (depends on 21) The screen unit as set forth in claim 21 wherein said signal generating element generates an inaudible signal. ### Claim 27 (depends on 21) The screen unit as set forth in claim 21 wherein said signal generating element generates a signal in the IR frequency range.
