In addition to light measurements, the tunnel video meters can also provide real-time traffic information relevant to lighting control systems. Hyperion™ TVM continuously detects vehicles, day and night, and delivers statistics on vehicle flow such as vehicle count and average speed. The system represents a more cost-effective solution than a two-sensor solution consisting of a diode-based meter and a traffic radar, with lower installation and maintenance costs.



The Hyperion™ TVM advanced series of light and traffic sensors for tunnel lighting control applications are being developed by Cipherstone Technologies AB - a well-established computer vision and optronics company celebrating its 10th year in operation
