VIA Relais

Devices that can mesh different sectors in the town with the SensyCity and Tegis detection environment to adjust and optimise street lighting according to different data.

In operation with Tegis, the VIA becomes a management node communicating by radio for the control and monitoring of a light point.

Power supply built into the module for simplified installation into lamppost bases.

Available with a combined SIR/VIA sensor.

  • Easy to install on all kinds of lampposts.
  • Designed for an urban environment with its two PIR sensors and discrete styling.
  • The adaptable installations can be re-configured and extended.
  • Combined with the Tegis ecosystem, the VIA receiver becomes a remote management node

The VIA recovers activation information from different sensors (vehicle radar, traffic sensor, weather, etc.) through a dry contact input and instantly sends it by radio to light points fitted with NOD receivers or SIR Wireless sensors.

The version including a DALI output also makes it possible to control the light point on which it is installed by a priority instruction sent to the LED driver (the level and duration can be set with the SensyCity application).

Combined with the Tegis control unit and the LoRa P2P communication module, the DALI version becomes an intelligent management node and provides control and monitoring of the point.

Night scenarios can be programmed in the VIA (version with DALI output) using the SensyCity application, with up to 5 time phases per night.
