ANPR for Warehouse Yard Management
ANPR for warehouse and logistics yards reads truck number plates at the gate with ordinary IP cameras and software. The system can match a plate against a booking or delivery list, open a barrier for authorised vehicles, and record the arrival and departure. It runs on standard ONVIF IP cameras and an Android device on site, and no dedicated ANPR camera is required.

What gate process ANPR replaces
- Manual gate paperwork is slow and easy to get wrong.
- Gate access is hard to control when every vehicle is handled by hand.
- Delivery matching between a truck and a booking is manual and hard to audit.
- Arrival and departure records are incomplete when they depend on a person writing them down.
What the system does at the gate
Reads the plate
A camera at the gate reads the truck number plate as the vehicle approaches.
Checks the rules
The software compares the plate with a booking list, a whitelist 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 event
Arrival and departure appear in the operator panel, so the gate log is complete.
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 at a warehouse gate?
A camera at the gate reads the number plate as the vehicle approaches. The software compares the plate with the rules for that site, such as a delivery booking or a whitelist, and then opens a barrier or starts a record. The operator panel shows the arrival and departure, so the gate log is complete without manual paperwork.
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 connect to our warehouse or transport system?
Where a deployment needs it, the system can exchange events with a warehouse, transport or access 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 passed between them.
Do we need a barrier at the gate?
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 arrival and departure record.
How is truck 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 gates, 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.
