Nine buildings, more than 2,000 remote controls — each opens only its own gates

01 / Investment context

What problem had to be solved?

The housing estate in Katowice has nine buildings. It has two shared entrances, and the individual buildings have their own underground car park gates. The system handles more than 2,000 remote controls, and each resident must have access only to their own part of the estate: to the shared barrier and to the car park gate assigned to that part — and to nothing else.

With this many remotes, changes are part of daily life, and the estate is still growing: new residents arrive, remotes get lost or become outdated. A lost remote that still opens the garage gate is a risk for everyone living in the building. If every change required a service visit at the gates, an outdated remote would keep working until that visit.

The investor’s goal: The investor adds users, changes the scope of access and disables lost remotes itself — remotely, without calling in a service technician — and each remote opens only the access points its owner is entitled to use.

What was designed?

Rights are assigned individually: a remote operates only the access points its owner may use — the shared barrier and the car park gate of their part of the estate. A resident has one remote for both. The system handles more than 2,000 remotes, and adding users, changing the scope of access and disabling lost or outdated remotes are done on the investor’s side, remotely, over the IP network.

For a similar project, GORKE today specifies a system built around Wiegand receivers. At every access point — the barrier of a shared entrance and each garage gate — a receiver (ORW-GE) converts the signal of the remote (PUK-102) into the Wiegand 26 or 34 protocol and passes it to the access controller just as a card reader does. The controller — a device from another manufacturer, administered over the IP network — holds the remote database and decides whether a given remote may open a given point; if so, it sends a signal to the drive’s control input.

In such a system, disabling a lost remote means changing one entry in the controller’s database: the receivers at the gates need no replacement or reprogramming, and all other remotes keep working. A new remote is added to the database and assigned to its owner’s access points.

What needs to be settled for a similar investment?

Before devices are chosen, what matters is the site’s conditions and how the system ties into the final installation.
