A property manager in Rotterdam calls: residents keep forgetting the barrier code, visitors park in the wrong spots, and no one has updated the access list in three years. She doesn't want another fob or card reader. She wants the barrier to open when a known car pulls up. That is what ANPR does, and it is simpler to set up than most managers expect.

ANPR stands for Automatic Number Plate Recognition. A camera captures a passing vehicle, reads the plate and sends that data as a text string to a system that decides within milliseconds whether the car gets access.
No fob. No PIN code. No app that needs updating or gets left at home.
The technology originated in law enforcement: speed cameras, toll roads, police scanners. Over the past five years the cameras have become compact enough and affordable enough for private car parks, residential complexes and office buildings. Deploying ANPR on a residential car park is now completely routine.
An ANPR camera is built for fast, accurate plate capture: high shutter speeds to freeze movement, infrared illumination for low light and night conditions, and a narrow focus zone calibrated to plate height.
Converting the image to text now happens on the camera itself. Axis, Hikvision, Bosch and Dahua all produce models with built-in OCR (Optical Character Recognition). The camera reads "AB-12-CD" directly from the sensor and sends that string over the network to the platform.
The practical benefit: no on-site server or separate computer is needed. No additional hardware that can fail or require maintenance. The camera handles the processing itself.
The platform receives the plate string and compares it against the access list in under a second. That list can contain residents, employees, regular visitors and a blocklist, all managed through the dashboard.
On a match: the barrier or gate opens immediately. The system logs the time, location and plate. The records appear in the dashboard and can be exported by date range, so nobody keeps them by hand in a spreadsheet.
No match: the barrier stays closed. The driver can then register as a visitor via WhatsApp, scan a QR code at the entrance or use the intercom, depending on how the operator has configured the system.
From arrival to an open barrier takes under two seconds, so most drivers roll through without stopping.
ANPR works best when the camera has a clear line of sight to the plate from an angle of no more than 25–30 degrees. Most problems come from installation, not software: a camera mounted too high, angled too sharply, or pointed into direct sunlight.
Outdoor installations in northern Europe need infrared illumination, because it gets dark early in autumn and winter. Without it, morning and evening performance drops sharply.
Modern ANPR software handles international plates reliably. German, Belgian, French and British formats are all recognised. Axis and Hikvision cameras achieve 98–99% accuracy at correctly configured installations.
The hard limit is severely damaged, painted over or extremely dirty plates. That's rare, and in those cases a human attendant wouldn't do better either.
The investment has two components: one-time and monthly.
One-time: cameras and installation. A suitable outdoor ANPR camera typically costs €400 to €900, depending on brand and specification. If you already have Axis, Hikvision, Bosch or Dahua cameras installed, they may already be ANPR-capable, which keeps one-time costs low.
Monthly: the platform subscription. Revtek starts at €175/month per location, covering the full dashboard, barrier integration, visitor registration via WhatsApp and push alerts for denied or unknown plates. See the pricing page for the full breakdown.
For a residential complex with 40 units, that works out to under €4.40 per unit per month. A part-time parking attendant doing weekly rounds typically costs €600 to €800 per month, plus the administration time on top.
For residential complexes it's the lowest-friction approach: residents do nothing except drive up, the barrier opens automatically. Visitors register themselves via a link or WhatsApp message without involving the concierge. More on that approach on the residential complexes page.
For offices, ANPR pairs well with an access control system like Paxton Net2 or Paxton10, linking parking events to building access and room occupancy. More on that combination on the Paxton integration page.
For hotels there are additional possibilities: linking reservations to a plate on check-in, reserving VIP spots and automatically registering guests on arrival. That reduces front-desk workload during peak arrival windows and late check-ins. More on the hotel page.
The most common question is whether existing cameras are already compatible. A demo answers that: we look at your site, the hardware already installed and what you need.
