Click-2-Enter Radio Receiver

Click2Enter does away with all of the cumbersome keys, access control codes, and remote control actuators, because every emergency response vehicle and responder carries the key-their mobile or portable radio transceiver. Just a simple 'click' of the radio transmitter button is all that's required to open gates, parking arms, doors, and commercial roll-up doors.

Click2Enter was developed to provide public safety personnel or any authorized user immediate access to gated residences; communities; or any security control mechanism. Other authorized users can even use the Click2Enter, as long as they are programmed into its frequency bank and have a radio transceiver. Click2Enter, compared to other emergency access control systems, will set the industry standard for many years to come.
