DISARMING A SECURITY SYSTEM BASED ON A PACKET AND DETECTED MOTION

摘要

A security system comprising a system control panel for arming and disarming the security system, a door sensing unit (104) comprising a first radio frequency (RF) transceiver and a portable device (150) comprising a second RF transceiver. The first RF transceiver is mounted proximate to a door (112) that defines a portion of a perimeter around an area to be monitored by the security system and is connected to the system control panel over a network. The second RF transceiver automatically transmits a device packet (178) which is received by the first RF transceiver when the second RF transceiver is within an RF detection field (168) of the first RF transceiver. The first RF transceiver then sends a disarm message to the system control panel over the network to disarm the security system based on at least the device packet (178) and without requesting a biometric input.
