License plate camera for parking entry and exit.

The barrier is the easy case

A car stops at the barrier, the plate sits in a known place at a known distance, and the camera can be mounted to look at it at a shallow angle. That is why a 4K fixed body is enough here and a dedicated lane camera is not needed.

The read becomes an event with the plate and a snapshot. That event opens a barrier, writes a record, or both, depending on what the site already has.

Light at the barrier

Headlights at night blow out a plate, and a lamp above the camera at the wrong angle turns it into a white rectangle. The usual fix is a light source beside the camera rather than above it, plus a short exposure that freezes the approach.

If the site cannot control the light, say so in the enquiry. It changes the model and the mounting height, and it is cheaper to decide before the bracket is on the wall.

What to send

Send a photo from the proposed camera position, at night if possible, with the barrier in the frame. Add the plate standard for the country, because character sets and plate sizes differ.

State where the read goes: a barrier controller, a VMS or an operator screen. The output format decides part of the configuration and it is not something that can be guessed after delivery.
