Your Gate Can Recognise Your Car. Here's How It Works — and How to Add It to Your Existing System

Pulling up to your gate and watching it open automatically as you arrive isn't a luxury reserved for five-star hotels and corporate headquarters anymore. Licence plate recognition and facial recognition for gate access has become genuinely accessible for residential properties — and in most cases, it can be added to the gate automation system you already have.

Here's how it works, what it enables, and why it's a more interesting upgrade than it might first appear.

What is licence plate recognition at the gate?

A camera positioned at your gate or driveway entrance captures an image of every vehicle that approaches. The system reads the number plate and compares it against a list of approved vehicles. If there's a match, the gate opens automatically. If there's no match, the gate stays closed and you receive a notification — often with a photo of the vehicle and plate — so you can decide whether to grant access remotely.

The whole process happens in a second or two. You drive up, the gate opens, you drive through. No remote control to find, no app to open, no code to enter.

And facial recognition?

Facial recognition works on the same principle but for people on foot. A camera at the pedestrian gate or front door captures an image of anyone who approaches. Recognised faces — family members, regular staff, a caretaker — trigger automatic entry. Unrecognised faces generate a notification with a photo, and you can grant or deny entry from your phone.

This is particularly useful for properties with frequent deliveries, regular contractors, or domestic staff who need regular access without the ongoing hassle of managing physical keys or codes.

How does it integrate with an existing gate?

This is where it gets practical. Most gate automation systems — the motors, the control boards, the safety beams — have a simple trigger input that causes the gate to open when it receives a signal. This is exactly how your existing remote control or keypad works: it sends a signal, the gate opens.

A UniFi Access controller can use this same trigger input. When the camera recognises an approved plate or face, the controller sends the open signal to your existing gate motor. The gate motor doesn't need to know or care where the signal came from — it just opens the gate.

In most cases, this means the camera and controller can be added to an existing gate system without replacing the gate, the motor, or the safety equipment. It's an addition, not a replacement.

What you get beyond the convenience

A complete access log

Every entry is recorded — time, date, and who or what triggered it. You can see at a glance when family members arrived, when the gardener came, when a delivery was made. This record is searchable and can be reviewed remotely at any time.

Remote access management

Need to let a tradie in while you're in Sydney? Open the gate from your phone. Want to check whether the cleaner has arrived? Check the access log. Need to revoke a contractor's access the moment a job is finished? One tap in the app. All of this happens remotely, with no need to be on the property.

No codes to manage or share

Gate codes are a security problem — they get shared, they get forgotten, they stay active long after they should have been changed. Moving to plate recognition or facial recognition eliminates this category of problem entirely. Access is tied to a specific vehicle or person, not a string of numbers that anyone could know.
