Intelligent Area Protection – DENSO’s Zone-D Laser Sensor protects complete Surfaces

Nowadays, safety and security risks are increasing in all aspects of life, both for individuals and in business. DENSO, part of the Toyota group, has invented an innovative security system: the Zone-D. Further information about the Zone-D security sensor system and how it can create a safer, more secure environment can be found at

Düsseldorf. According to the statistics portal Statista, security surveillance is a growing market: Revenue in the security segment is expected to show a rapid annual growth rate. As a new innovation, DENSO WAVE EUROPE, part of the Toyota group, has developed the Zone-D. The modern laser sensor 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: “Many companies use line and curtain type sensors, 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, which makes it hard for intruders to avoid being detected.”

Intelligent Networking with the Zone-D Laser Sensor from DENSO

If connected to security equipment like PTZ cameras, lights or sirens, the Zone-D laser sensor is able to send signals and activate these devices, when detecting an object. The laser sensor can differentiate between people, animals, cars, and other objects. The object filtering of the laser sensor enables false alarms to be avoided. Another advantage is that the Zone-D laser sensor is reliable under all lighting conditions: it can detect objects in the dark or at illuminances of up to 100,000 lux. Even rain and fog are no issue for the innovative security device.

On the YouTube channel of DENSO WAVE EUROPE, a video shows how the Zone-D laser sensor works. Compared to a CCTV, the Zone-D auto-tracking system covers and records over a much wider range:

How does the Zone-D Laser Sensor work exactly?

DENSO's Zone D Laser Sensor

The Zone-D laser sensor 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 signal needs to be set for when objects are moving in this area. But if an area needs extra protection, for instance, where a safe is located, this area can be marked as a red zone and an alarm can be activated when intruders enter.

The Zone-D advanced security system sends notifications immediately to the user’s computer or monitoring area. In detail, 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. Another option for more protection is the damage prevention: In critical areas, intimidation systems such as lights, flashlights or sirens can be activated. Additionally, vocal warnings can be made remotely and electric locks can be engaged to prevent any damage inflicted to the property all while viewing the intruder’s actions in real-time. Live videos can be verified with connected portable terminals such as PCs and smartphones.

Zone-D Security Sensor System during the Corona Pandemic

In the current lockdown situation during the Corona pandemic, where social distancing is becoming the norm, the Zone-D laser sensor can help enforce this. By defining detection zones,

people can be detected in a zone. Should movement outside the zone be seen, the Zone-D laser sensor 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.

Furthermore, the Zone-D laser sensor supports ‘crossing detection lines.’ These can be used where entrances and exits are defined. For example, people can be detected, if they use the wrong route. This feature of the Zone-D laser sensor can also be used to detect when a position at, for example, a ticketing booth becomes free, notifying the queue that the booth is available and enabling prompt use. Some example applications, especially during Corona, include supermarket entry queues, border or passport control, and ticketing at theme parks or conferences.

Various Application Areas

The application areas in which the Zone-D laser sensor can be used are diverse: from car dealers and stores, via factories and logistics companies, railways and airports to power plants and water plants. The Zone-D sensor security system can be used in both public spaces and residences alike. The laser sensor can detect vehicles and see customers arriving at stores and car dealers, manage customers’ shipments securely or monitor power plant equipment.

In Japan, home to the Toyota group, the Zone-D sensor security system has already been installed in approximately 500 projects. Installations of the modern security sensor 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.
