Methods and systems are described herein for remotely or wirelessly controlling access to dwellings, buildings and/or properties. In one aspect, an electronic access system comprises: a plurality of independent access control devices (115, 125, 135, 145, 155, 165) for controlling entry and/or exit at respective access points and at least one remote control device (170) adapted to wirelessly transmit control signals to the access control devices (115, 125, 135, 145, 155, 165) and wirelessly receive feedback signals from the access control devices. The at least one remote control device (170) is adapted to indicate status information based on receipt of the feedback signals. The plurality of access control devices (115, 125, 135, 145, 155, 165) may be adapted to operate mechanical, electrical or electro-mechanical devices for enabling and/or disabling access in response to receipt of a wireless control signal. |

1. An electronic access system for providing selective access to a building or property, said electronic access system comprising:
a plurality of independent access control devices for controlling access to said building or property, each of said access control devices comprising a radio frequency receiver for wirelessly receiving control signals; at least one remote control device adapted to wirelessly transmit control signals to said access control devices and wirelessly receive feedback signals from said access control devices; and at least one first class remote control device and at least one second class remote control device; wherein said plurality of access control devices are adapted to permanently cease to operate a respective mechanical, electrical or electro-mechanical device in response to receipt of a wireless control signal from said at least one first class remote control device after first receipt of a wireless control signal from said at least one second class remote control device but not to disable access in response to the at least one second class remote control device; wherein said at least one remote control device is adapted to indicate status information of said access control devices based on receipt of said feedback signals; and wherein said remote control device is adapted to:
determine presence or absence, using said RFID reader, of a radio frequency identification (RFID) tag in response to operation of said remote control device by a user; andtransmit a control signal only if said RFID reader detects presence of a valid RFID tag;
wherein said remote control device and said RFID tag comprise physically separate devices. |
