It measures the speed, reads the plate, and records the violation in one housing.

A traffic enforcement camera with a built-in millimeter-wave radar and dual-color LED illumination. It covers 1 to 2 lanes and captures speeding, wrong-way driving, and illegal lane changes while telling motor vehicles from motorcycles.

Key features

140dB

Wide dynamic range

It balances exposure against backlight and keeps plates readable at night.

61–62GHz

Built-in speed radar

It measures vehicle speed from 5 km/h to 180 km/h for up to 32 targets.

3units

Dual-color LEDs

They switch between 850 nm infrared light and 3500 K warm light, lighting from 23 m to 30 m.

400m

Detection at the tele end

At the tele end it reaches 400 m for detection and 80 m for recognition.

1TB

Local storage

When the link drops, the TF card holds the images and sends them to the platform and the FTP server once the network returns.

Low consumption

It draws 8 W with the light off, 12 W on infrared light, and 17 W on warm light.

IN DAILY USE

Enforcement in one housingRadar, illuminator, and lens sit in the same chassis, so installation runs from a single point.

Endurance in harsh conditionsThe sealed housing stays closed against rain, dust, and impact.

List controlIt compares a recognized plate against the allowlist and the blocklist at once, and triggers unlicensed vehicle and intrusion alarms.
