The issue of safety in the field of photovoltaic systems is strongly felt due to the continuous increase in theft of copper as well as of the panels themselves.

Photovoltaic systems have the following common characteristics:

  • Particularly extensive perimeters
  • Absence of electricity and data network along the perimeter
  • located in isolated areas that can be easily attacked
  • absence of on-site supervision

The attacks are increasingly targeted, once the perimeter lines have been evaded, the intruders can act undisturbed, hiding under the panels and acting in the dark, when the system does not produce energy.

The manager notices the theft the next morning, when he notices that the plant is not producing.

After repeated thefts in the same plant, the insurances no longer cover the value of the plant.

This criticality is deeply felt by the managers who are increasingly looking for reliable and effective solutions over time and which can alert the vigilance of an attempted break-in in real time.

The approach normally adopted for the protection of photovoltaic systems is the creation of a protection line along the perimeter using underground cables or microphone barriers.

This type of protection generates numerous false alarms which over time lead the system to become less and less reliable. Furthermore, the maintenance costs are expensive.

Furthermore, once they enter the plant, intruders are no longer detected.

Thermal Radar Sensors

Thermal Radar, distributed in Italy by Crisma Security, is a unique and innovative technology for the immediate detection of a potential perimeter intrusion . The Thermal Radar combines the peculiar characteristics of thermal sensors and their ability to see in the absence of lighting, with the characteristics of rotary radar sensors that allow a 360 ° long-range panoramic scan .

The solution proposed by Crisma Security for the protection of photovoltaic systems involves the use of area protection technologies, such as Thermal Radar combined with SightLogix intelligent thermal cameras, integrated into a single management console.

The common feature of these technologies is that of being able to detect the position and number of intruders on the entire surface of the site. The high coverage ranges allow a drastic reduction in the number of sensors to be installed in the field with a consequent reduction in installation and maintenance costs.

Moreover, thanks to the protection of the area and not only of the perimeter line, intruders are also detected within the site and their position can be promptly communicated to the surveillance, for rapid intervention.

The detection ranges are as follows:

  • Thermal Radar, innovative thermal camera that allows a 360 ° view, detects a person up to 250 radius
  • SightLogix Intelligent Thermal Cameras, detects a person up to 600m away

The detection area can be freely defined during the system configuration phase, in order to detect intrusion attempts with high precision only where it is actually necessary.

It is also possible to define alarm policies for time bands and days of the week to guarantee automatic supervision when there is no presence of operators on site.

The Thermal Radar has a consumption of only 5-7Watt, much lower than the most popular traditional technologies.

Paying attention to the choice of accessory components (industrial PC, 4G modem, etc.) and selecting devices with low consumption characteristics, through the use of the TIR it is possible to achieve considerable energy savings over time, compared to traditional technologies,

Thermal Radar protects the plant area with the help of integrated PTZ cameras for visual recognition of targets, Sightlogix cameras allow the same level of protection in the perimeter lines, the Smart Alarm suite provides a single and integrated management console , IntelliDetc provides targeted video analysis on existing cameras and PTZ, Anywall allows the visualization of alarms on videowall walls.
