| 20090154768 | METHOD OF MOTION DETECTION AND AUTONOMOUS MOTION TRACKING USING DYNAMIC SENSITIVITY MASKS IN A PAN-TILT CAMERA - A method of identifying motion within a field of view includes capturing at least two sequential images within the field of view. Each of the images includes a respective array of pixel values. An array of difference values between corresponding ones of the pixel values in the sequential images is calculated. A sensitivity region map corresponding to the field of view is provided. The sensitivity region map includes a plurality of regions having different threshold values. A presence of motion is determined by comparing the difference values to corresponding ones of the threshold values. | 06-18-2009 |
| 20090015405 | TAMPER DETECTOR FOR A SECURITY SENSOR - A security arrangement includes a mounting device having an upstanding wall. The mounting device is mounted to a surface of a structure such that the wall is oriented substantially perpendicular to the surface. A security sensor senses an event that occurs outside of the security arrangement. A tamper detector is attached to the security sensor and includes an optical emitter, an optical receiver, and a slot disposed between the emitter and the receiver. The emitter transmits optical energy that is received by the receiver through the slot. The wall of the mounting device is received in the slot when the tamper detector is coupled to the mounting device to thereby block the transmission of the optical energy from the emitter to the receiver. A controller is communicatively coupled to the receiver and produces a tamper signal in response to the receiver receiving the optical energy. | 01-15-2009 |
