Abstract
A remote door locking/unlocking system includes both telephone receiver/DTMF decoder circuitry and a wireless radio frequency or infrared sensor for enabling the system to be actuated either by a portable short range transmitter or by any telephone. The telephone circuitry or handset may be removably installed in the door so that it can be used with a variety of different cellular or satellite communications systems. An alternative to DTMF and/or radio frequency or infrared activation, speech recognition could be used to interpret voice commands transmitted over the network or picked up by a microphone.
