ANPR for Office Buildings
ANPR for corporate office parking reads vehicle number plates at entry and exit with ordinary IP cameras and software. It can open a barrier for authorised vehicles, apply separate rules for staff, visitors and contractors, or simply log the visit. It runs on standard ONVIF IP cameras and an Android device on site, and no dedicated ANPR camera is required.
Complete ANPR overview: ANPR Parking System.
What the system does at an office site
Reads the plate
A camera reads the number plate as the vehicle enters or leaves the car park.
Applies access rules
The software compares the plate with a staff list, a visitor booking or another rule set for the site.
Controls the barrier
If a barrier is connected, it opens for authorised vehicles. A barrier is optional.
Records the visit
Arrival, departure and duration appear in the operator panel.
Runs on IP cameras
Standard ONVIF and RTSP cameras. No dedicated ANPR camera is needed, and existing cameras can often be reused.
One device, two cameras
An entry and an exit camera can run on a single Android device on site.
What we measured
The figures below come from our own tests in September 2026, not from a manufacturer datasheet. They were measured on two Android phones with two 1080p IP cameras at 20 fps.
- Plate confirmation in a two-camera test (16 clips, 24 plates): 24 of 24 plates, 0 false reads, median 0.6 s.
- Plate detection per frame: 38-57 ms. OCR of a plate crop: 15-20 ms.
- One camera: 24-26 frames per second. Two 1080p cameras at once: about 8 frames per second in total.
- Keep the plate at least about 30 px high in the frame. Camera position and framing matter more than zoom.
- A plate was confirmed in rain at 02:37, and two more at night at 04:05 and 04:36.
- The software detects a stalled stream after 15 s without progress and reconnects automatically.

Frequently asked questions
How does ANPR work for office parking?
A camera reads the number plate when a vehicle enters or leaves the car park. The software compares the plate with the rules for the site, such as a staff list, a booking or a visitor rule, and then opens a barrier or starts a parking record. The operator panel shows arrivals and departures in one place, so access can be reviewed without a badge or a manual log.
Does ANPR run on standard IP cameras?
Yes. The system runs on IP cameras that support ONVIF and RTSP, so it is not limited to dedicated ANPR cameras. Existing IP cameras that give a clear view of the plate can often be reused. Our tests used 1080p cameras at 20 fps, and no dedicated ANPR camera was needed.
How accurate is the plate recognition?
Our figures come from our own September 2026 two-camera test, not from a vendor datasheet. In that test the deployed setting confirmed 24 of 24 plates with zero false reads, with a median of 0.6 s from the vehicle appearing to confirmation. The test used 16 clips and 24 plates from an entry and an exit camera working together; a plate counted as correct only when both cameras agreed. That is a small sample, so we present it as a test result, not an accuracy percentage.
Can the system sync with our staff records?
Where a deployment needs it, the list of allowed plates can be kept in step with an external system through an API. That is scoped during the site audit, because it depends on the system you already run and what data has to be exchanged.
Do we need a barrier?
No. A barrier is optional. With a barrier, the system can open it for authorised vehicles. Without one, it runs as a recognition and logging system, which still gives a complete record of who entered and left.
How is plate data handled under GDPR?
A number plate identifies a person, so it is personal data under GDPR. The system processes plate data locally on site, and retention is configured by the operator. We help customers put the required documentation in place, including the record of processing and the information clause.
What does the price depend on?
It depends on the number of lanes and entry points, whether usable IP cameras already exist, whether a barrier is needed, which systems the software must connect to, and the country of deployment. We prepare an itemised quote after a site audit.
