Tracking, presence verification and locating features as part of a security system

An electronic tag for use with a presence and location verification feature, comprising:

• a memory for storing an identifier;
• a receiver for receiving a wireless signal encoded with an identifier, and another wireless signal from one of a plurality of detectors, the another wireless signal comprising information indicating a location of the electronic tag;
• a control for comparing the stored identifier to the received identifier;
• and
• a transmitter responsive to the control for transmitting a wireless signal for verifying a presence and location of the electronic tag when the stored identifier matches the received identifier, the wireless signal for verifying a presence and location comprising the stored identifier and the information indicating the location of the electronic tag.

A detection apparatus, comprising:

• a detector at a specified location for detecting the presence of a living being within a specified range;
• a transmitter at the specified location;
• and
• a control responsive to the detector for controlling the transmitter to transmit a wireless signal with a specified energy based on the specified range, the wireless signal comprising information indicating the specified location;
• wherein the wireless signal from the transmitter, when received by an electronic tag within the specified range, causes the electronic tag to transmit a wireless signal with data to a security system, the data comprising an identifier of the electronic tag and the information indicating the specified location.

An electronic tag, comprising:

• a memory for storing an identifier;
• a receiver for receiving a first wireless signal from a security system and a second wireless signal from one of a plurality of detectors;
• a transmitter for transmitting a third wireless signal;
• and
• a control responsive to receipt of the first wireless signal by the receiver for controlling the transmitter to transmit the third wireless signal to the security system;
• wherein the third wireless signal is encoded with the identifier and the location of the electronic tag and other data for use by the security system.

A method for controlling a security system, comprising:

• detecting the presence of a living being within a specified range of a detector at a specified location;
• responsive to the detecting, controlling a transmitter at the specified location to transmit a wireless signal having a specified energy based on the specified range, the wireless signal comprising information indicating the specified location;
• receiving the wireless signal at an electronic tag when the electronic tag is within the specified range;
• and
• responsive to the receiving, transmitting a wireless signal, which includes data for use by the security system, from the electronic tag to the security system, the data comprising an identifier of the electronic tag and information indicating the specified location.
