Abstract
The sensitivity of a motion sensor or detector in a security system is adjusted by a remotely-transmitted signal, such as from a user interface device in the security system. In another approach, a pet wears a transmitter on its collar that transmits a wireless signal to command the motion sensor to adjust its sensitivity, e.g., by entering a pet immune mode, when the pet is in the room that is protected by the motion sensor. In another approach, a remote monitoring site sends instructions to the motion sensor via a communication interface. The sensitivity can be adjusted by adjusting a pulse count, optical gain, or electrical or optical sensitivity of the motion sensor.

12. A motion detector, comprising;
-
a component for sensing electromagnetic radiation that is indicative of the presence of a living being;
a control responsive to the component for determining, in accordance with the sensed electromagnetic radiation, whether to trigger a signal indicating that the living being has been detected; and
a receiver for receiving a remotely-generated signal for adjusting a sensitivity of the motion detector;
wherein the control is responsive to the remotely-generated signal for adjusting a sensitivity with which the component senses the electromagnetic radiation. - View Dependent Claims (13, 14, 15)
