LICENCE PLATE RECOGNITION (LPR)

Know which vehicles
are at your gate.

LPR uses a camera and software to read vehicle plates at an entrance. It can let registered vehicles in, flag unknown ones and keep a record of every entry. How well it works depends on your site.

WHAT LPR CAN DO FOR YOU

Less waiting at the gate.
A clearer record of every entry.

Faster entry for registered vehicles

Residents, tenants or staff on your authorised list can be let in without cards or remotes, where the barrier supports it.

Clearer visitor handling

Plates that are not on the list can be held for a guard check, or matched to visitors registered in a vehicle management system.

A searchable entry record

Each read is stored with the time and a plate image, so you can check who entered when something needs looking into.

HOW IT WORKS

From camera to barrier
in five steps.

01

Capture

A camera aimed at the lane captures the plate as the vehicle slows or stops.

02

Read

Software turns the plate image into text.

03

Match

The plate is checked against your authorised and visitor lists.

04

Act

The barrier opens, the guard is alerted, or the entry is simply logged, depending on your rules.

05

Record

The read, image and time are stored for reports and later checks.

What affects how well it reads

  • Camera angle, height and distance to the plate.
  • Lighting, headlight glare, low sun and rain.
  • Dirty, damaged or covered plates, and non-standard plate formats.
  • Vehicle speed and where vehicles stop.
  • Motorcycles and rear plates, which need separate planning.

No LPR system reads every plate. Plan what happens when a plate isn’t read: guard override, intercom or manual entry.

What it needs to connect to

  • Your barrier or gate controller, which must accept a signal from the LPR system.
  • Power and a reliable network connection at each lane.
  • Software that holds the authorised list, often a vehicle management system.
  • Your CCTV recorder, if plate reads should link to recorded video.
  • Someone responsible for keeping the vehicle list up to date.

What affects the cost

  • Number of lanes, counting entry and exit separately.
  • Camera and software licence for each lane.
  • Barrier changes or new controllers, if needed.
  • Cable distance from the lane to the network and power.
  • Ongoing support and maintenance.
