<p>car park gate</p> <p><b>New page</b></p><div><br /> == Car Park Gate ==<br /> <br /> At Ujima House, the car park barrier is access controlled. The building landlord approached us with a request to make the car park unusable for non-authorised users. The list of non-authorised car park users is a small number.<br /> <br /> This wiki article will not include any security-sensitive information.<br /> <br /> === Hardware in place ===<br /> <br /> Nice automation barrier system, connects to Chameleon Controls AC230SADK keypad. By the look of it, this just signals via a relay to the barrier, rather than using some fancy protocol. (The barrier system itself can be networked, using some weird proprietary Bluebus two-wire connection)<br /> <br /> The Chameleon Controls keypad has a low-frequency (433MHz) RFID reader.<br /> <br /> The barrier itself has a radio remote with two buttons, the top button opens/closes the barrier to full extent<br /> the lower button on the remote opens/closes the barrier to about 60 degrees.<br /> <br /> Possibilities: ANPR with blacklist.</div>
