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's exactly what ANPR does — and it's 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 — in 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 not just a security camera with smarter software. It's purpose-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.
The recognition itself — converting the image to text — now happens on the camera. 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 manageable through the dashboard.
On a match: the barrier or gate opens immediately. The system logs the time, location and plate — visible in the dashboard and exportable by date range. No manual record-keeping, no spreadsheet with two conflicting versions.
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.
The whole sequence — from arriving to barrier-open — takes under two seconds. Most drivers notice nothing. They pull up, the barrier rises, they drive through.
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.
For outdoor installations in northern Europe — with early darkness in autumn and winter — infrared illumination is not optional. 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–€900, depending on brand and specification. If you already have Axis, Hikvision, Bosch or Dahua cameras installed, they may already be ANPR-capable — in which case one-time costs are minimal.
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–€800 per month — before you factor in administration time.
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 — no concierge intervention needed. 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 at the moments it matters most — peak arrival windows and late check-ins. More on the hotel page.
The most common question is whether existing cameras are already compatible. That's exactly what a demo is for: we assess your site, your current hardware and what you actually need. No scripted pitch — just a practical look at what's feasible.
