Sign Angel is a new sensor by Synapses to georeference and live monitor of highways construction sites.

Sing Angel can be applied to each road/traffic sign and it allows to detect all possible crashes or rorations of movable signs, promptly sending an alarm to the control room.


Sound Guard uses the natural principle that binds every sudden chenge of state to a strong vibration (sound). Just as it happen with thunders that can be heard KMs away.
