VIA Relay

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

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

Available with a combined SIR/VIA sensor.

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).

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