ZKTeco LRM300 License Plate Recognition System

Overview

The ZKTeco LRM300 is a camera that reads vehicle number plates and opens the barrier for vehicles on its list, so registered cars enter a car park without a guard, a card or a remote. It suits factories, government buildings, residential societies and office car parks, especially where the same vehicles come and go every day. Once the allow and block lists are loaded through a web browser it works on its own, without a server, and opens the barrier directly.

Is it right for you?

• It suits a lane where vehicles slow to 10 km/h or less and stop 3 to 5 m from the camera.
• It reads number plates in the Indian format only.
• It can run without a server: lists up to 1,000 allowed and 1,000 blocked plates, with 8,000 monthly parking entries, are held on the camera.
• It is weatherproof (IP65) and works from -30 to 70 °C, so it can be mounted outside at the gate.
• If visitors also need to get in, pair it with a ticket system, intercom or guard button, since it only opens for plates on its list.

Key features

• Number plate recognition (ANPR) running on the camera itself, with an embedded deep learning algorithm on a 0.5 TOPS processor.
• Recognition accuracy of 99% or more by day and by night.
• Reads at 3 to 10 m (3 to 5 m recommended) with vehicles moving at up to 10 km/h.
• 1/2.8 inch 3 MP sensor with a 3.2 to 11.1 mm autofocus lens, working down to 0.1 lux.
• Stores 1,000 allowed plates, 1,000 blocked plates and 8,000 monthly parking entries, plus 10,000 entry and exit records and 10,000 captured pictures.
• Two relays, RS485, Wiegand in and out, auxiliary input and output and a barrier status input, so it can drive the barrier and talk to an access panel.
• H.264, H.265 and MJPEG video over TCP/IP (10/100 Mbps), RTSP, P2P and PUSH, with a microSD slot (8 GB fitted, up to 128 GB).
• Output per read: the plate number, a picture of the plate and the time.

What else you need

A boom barrier for it to open, a 12 V DC supply (it draws 7.5 W or less) and network cabling to the camera. Recognition is triggered by video by default, or by a loop detector in the road if you prefer. For central management of several lanes or sites, ZKTeco parking software; for a single lane the camera can run on its own.

Installation

A gate automation or access control installer should fit it. Mount it so the stop point is 3 to 5 m from the camera, wire the relay to the barrier, run the 12 V DC supply and network cable, then load the vehicle lists through the web browser. The housing is 460 x 156 x 120 mm and weighs 2.5 kg.

Software and licences

The vehicle lists are set up through a web browser on the camera. ZKTeco parking software adds central management when you have more than one lane or want reports in one place.

Before you buy

• Supported plate region: India. Check that your plates match before ordering.
• Vehicles must be moving at 10 km/h or less for a reliable read.
• Keep the camera 3 to 5 m from where vehicles stop; it reads up to 10 m.
