With state-of-the-art DENSO technology, it is possible to protect all types of perimeters reliably: thanks to the Zone-D laser sensor. Unlike line and curtain type sensors that detect from point to point, Zone-D detects large areas, making it hard for intruders to avoid being detected. If being connected to security equipment like PTZ cameras, lights or sirens, Zone-D is able to send signals and activate these devices, if an object is detected.
