Zone-D Laser Sensor Security System

The Zone-D Laser Sensor detects precisely the position of moving objects!

Nowadays, safety and security risks are increasing in all aspects of life. DENSO, part of Toyota group, has invented an innovative security system: the Zone-D.

The Zone-D detects accurately the position of moving objects, making it possible to protect all types of perimeters reliably. Viv Bradshaw, Manager Business Development Europe and Technology Consultant at DENSO WAVE EUROPE, explains: “Often line and curtain type sensors are used, but these models can only detect objects from point to point. Our Zone-D, however, covers not only a wide area but also detects on the surface, making it hard for intruders to avoid being detected.”

Compared with a CCTV, the Zone-D auto-tracking system covers and records over a much wider range.

If connected to security equipment like PTZ cameras, lights or sirens, the Zone-D is able to activate these devices when detecting an object. It can differentiate between people, animals, cars, and other objects. With the object filtering function, false alarms can be avoided. Furthermore, it can detect objects in the dark or at illuminances of up to 100,000 lux. Even rain and fog are no issue.

But how does it work exactly? The Zone-D detects surfaces of about 60 by 30 meters. They can be clustered in individually configurable zones, and thus, different areas can be set. For example, a green zone can be the safe area where no alarm needs to be set. But if an area needs extra protection, this area can be marked as a red zone and an alarm can be activated when intruders enter. Up to 13 different zones are available, enabling the appropriate actions to be taken depending on the threat level.

When an intruder is detected within the monitoring area, the camera automatically zooms in to track and record the intruder’s action. That is when an immediate email is sent to the user’s device. In critical areas, intimidation systems such as lights, flashlights or sirens can also be activated. Vocal warnings can be made remotely and electric locks can be engaged to prevent any damage inflicted on the public space all while viewing the intruder’s actions in real-time.

Zone-D during the Corona Pandemic

In the current lockdown situation where social distancing is becoming the norm, the Zone-D can help enforce this. By defining detection zones, people can be detected in a particular zone. Should movement outside the zone be seen, the Zone-D can enable the playback of a pre-recorded message to help enforce social distancing.

Additionally, a PTZ camera can track that person and any security or monitoring person can provide the human-touch instead. Some example applications include border or passport control, supermarket entry queues, and ticketing at theme parks or conferences.

Various Application Areas

The application areas in which the Zone-D can be used, in addition to the needs during the Corona pandemic, are diverse. No matter the location – airports, power plants, factories, museums, car dealers, condominiums, and even parks – dangers are present everywhere. The laser sensor can perfectly be used in public spaces but also in residences.

In Japan, home of the Toyota group, the Zone-D has already been installed in approximately 500 projects. Installations have also been realized in Singapore and Thailand. They have proven that the laser sensor is ideal for monitoring critical infrastructure, like railway crossings, train platforms, and airport perimeters, as well as water, electricity and gas installations.

“The security sector might be new to DENSO WAVE in Europe, but we have already shown that our product increases the protection in the areas where it is installed – and we are looking forward to protecting more companies and people with our innovative Zone-D,” Bradshaw sums up.
