Abstract
A system, method and apparatus is described, for monitoring entry doors and windows for unauthorized entry. Passive objects are installed onto movable portions of doors and windows in the structure. An optical base station is mounted to a wall or ceiling of the structure in view of at least some of the passive objects. The passive objects are configured to reflect visible and/or infrared light and, in some cases, comprise a unique, geometric shape. The optical base station monitors the passive objects and when a passive object is moved, for example, when a door or a window is open, the optical base station senses the movement and, in response, transmits an alarm signal to a security system central controller, which may then cause a security response to occur.
Claims14
A system for monitoring entry doors and windows for unauthorized entry, comprising:
- a passive object configured for installation onto an entry door, and
- an optical base station configured for visually monitoring the passive object and for determining, based upon a determined change in distance between the optical base station and the passive object, when the passive object has moved.
An optical base station, comprising:
- an optical sensor configured to generate electronic signals indicative of a viewing area of the optical sensor;
- a processor, coupled to the optical sensor, configured to receive the electronic signals from the optical sensor and to determine, based on the electronic signals, a presence of a passive object in the viewing area of the optical sensor and further configured to determine, based on the electronic signals indicating a change in distance between the optical base station and the passive object, when the passive object has moved.
A method, performed by an optical base station, for monitoring entry doors and windows for unauthorized entry, comprising:
- generating, by an optical sensor of the optical base station, electronic signals indicative of a viewing area of the optical sensor;
- providing the electronic signals to a processor of the optical base station;
- determining, based on the electronic signals, a presence of a passive object in the viewing area of the optical sensor;
- and
- determining, based on the electronic signals indicating a change in distance between the optical base station and the passive object, when the passive sensor has moved.
