Abstract: Tracking, presence verification, and locating features are incorporated into a security system that includes a user interface device with a display, keypad and associated transceiver. Wireless RF electronic tags are attached to different objects, e.g., an inanimate object, or a living being such as a child or pet. To verify the presence of an object associated with a tag, the user instructs the user interface device to transmit a wireless signal to the tag. The tag responds, when within range, by returning a wireless signal. In another aspect, a person is detected such as at the entry to a home, and a low-power transmitter at the entry sends a signal to the electronic tag. The electronic tag responds by transmitting data to the security system to cause it to take a desired action. The presence of a person, such as a child, in an unauthorized area can trigger an alarm.
