DHI-ITARD-024MA-H Radar
The radar can be installed at any position above the lane to detect vehicles of 1–4 lane(s) within
15–45 m. This radar also sends snapshot trigger signal when a vehicle arrives at designated
position, and detects the lane and the vehicle speed.
Features
 One radar can detect up to 32 vehicles from 1–4 lanes.
 Precisely detects speed and position of vehicles within 18–35 m.
 Flexible installation (front mount or side mount), commissioning through wireless handheld
device, and visual commissioning interface.
 Capable of detecting vehicles making U turns or changing lanes.
