HC-M250PRODUCT OVERVIEW
Long-range vehicle data for networked traffic systems
HC-M250 extends multi-target traffic sensing to 300 metres and delivers data over Ethernet, giving integrators one radar source for monitoring, vehicle-road coordination and signal control.
Position and speed
Output target ID, X/Y coordinates and real-time speed for downstream decision and visualization systems.
Traffic-flow statistics
Calculate volume, average speed, lane occupancy, headway and distance between vehicles.
Long-range road coverage
Monitor approaching and departing traffic at up to 300 metres without relying on ambient light.
ETHERNET DATA & INTEGRATION
Long-range traffic data over a network connection
HC-M250 provides target tracks and traffic-flow information through Ethernet communication for traffic monitoring platforms, vehicle-road coordination and traffic signal control. For the detailed communication protocol and integration documentation, please contact our technical team.

INSTALLATION & CONNECTION
Plan the site around long-range road visibility
HC-M250 can be deployed for roadside or overhead road monitoring. Mounting height, angle and network layout should be confirmed for the actual lane geometry and required 300 m coverage.
Use one radar for two-way traffic monitoring where the road geometry supports coverage.
Confirm the clear line of sight, target mix and site conditions during project evaluation.
Connect target and traffic-flow data to the roadside controller or central platform.
Plan power, surge protection and field cabling for the selected mounting position.
PROJECT SUPPORT
Evaluate the 300 m monitoring corridor before integration
Share lane count, road width, required range, mounting position, network environment and expected data. Our team can help confirm whether HC-M250 fits the site.

TECHNICAL FAQ
Common HC-M250 questions
What data can the HC-M250 output?
It can provide target ID, coordinates, speed, length, width and trajectory information, together with traffic-flow statistics such as volume, average speed, lane occupancy and headway.
How many lanes and targets can one radar monitor?
The HC-M250 supports two-way monitoring across up to eight lanes and can track up to 128 targets, subject to road geometry and installation conditions.
Does the radar work at night or in bad weather?
Radar detection does not rely on ambient light and is designed to operate through darkness, dust, rain and snow.
Can the HC-M250 be used for traffic enforcement?
No. HC-M250 is intended for traffic monitoring, vehicle-road coordination, signal control and analytics. Select a suitable enforcement radar when legal metrology or evidence workflows are required.
How does the radar connect to a traffic system?
HC-M250 uses Ethernet communication. For the detailed communication protocol, please contact our technical team and share your integration requirements.
What information should I provide before ordering?
Provide the number and width of lanes, required detection distance, mounting height and angle, target types, output requirements and intended system application.
