Automatic thermal image detection equipment.

It consists of two cameras-infrared camera and a visible light camera which can monitor inside of tunnel in the same way as CCTV, and also can detect fire, heat, smoke and stopped vehicles before a fire break out.

Pumpless CO-meter

Monitors the CO concentration in the tunnel and measured values can be used as input data for controlling ventilation equipment. It has compact in design and has no moving parts such as pump, and has excellent maintainability.

Laser Traffic Counter 

It detects vehicles using laser light and measures traffic volume and vehicle speed. It can be installed to existing structures such as portal gates and roadsides poles. Regardless of day or night, it is not affected by rain or other weather conditions, and has high detection accuracy.

Smoke Exhaust Ventilation Control Panel

Ventilation equipment is controlled based on wind speed measurements to control the airflow in the tunnel. In the event of fire, the system suppressed the diffusion of smoke and helps to create a safe evacuation environment for users inside tunnel.
