Project:Car Park Gate

Car Park Gate

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.

This wiki article will not include any security-sensitive information.

Hardware in place

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)

The Chameleon Controls keypad has a low-frequency (433MHz) RFID reader. The tag we've been given doesn't work with it.

The barrier itself has a radio remote with two buttons, the top button opens/closes the barrier to full extent the lower button on the remote opens/closes the barrier to about 60 degrees.

Possibilities: ANPR with blacklist. For everyone not on the blacklist, the barrier arm works as normal.
