ANPR and visitor parking: making Melbourne car parks work

Car parks are one of the most common sources of resident complaints: visitor bays full, boom gates slow, unauthorised cars parked for days. ANPR can fix a lot of that, but only if it is designed around how the building actually operates.

What ANPR does well

Automatic number plate recognition reads a vehicle plate and compares it with a list: residents, authorised visitors, trades, couriers or temporary permits. If the plate is on the list, the gate opens; if not, the driver is directed to an intercom or visitor process.

It is fast, hands-free and creates a record of every vehicle entry and exit. That record is useful for parking disputes, security incidents and understanding how the car park is actually used.

Where ANPR struggles

• Dirty or obscured plates - particularly in wet or dusty car parks.
• Bad lighting - glare, headlights and shadows reduce read rates.
• Lane design - sharp turns and short approach distances make capture unreliable.
• Shared plates - one permit used by multiple cars.
• Visitors without a booking - ANPR needs a visitor process, not just a camera.

Design the visitor journey first

The technology is the easy part. The harder question is: how does a visitor get in? A good process might be a QR code or link sent by the resident, a booking portal, or an intercom call to the apartment. The ANPR system then checks the plate against the approved list for the right time window.

Always provide a fallback: an intercom, a phone number and a manual release for deliveries, hire cars and plate changes.

Integration with access control

ANPR works best when it shares data with the access control system. A resident's vehicle, fob and mobile credential can be managed in one place, and a departed resident can be removed from both the building and the car park at once. Vehicle events can also be linked to CCTV for a complete record of an incident.

Privacy and fair use

Number plates are personal information. Publish a clear privacy notice, limit who can search the vehicle log, set a retention period and avoid using the system for unrelated surveillance. Give residents a simple way to correct a plate or add a temporary vehicle.
