As an increasingly important provider of electricity across the globe, solar parks need to be effectively secured. The threats these installations face are the same as for any other energy producing facility: vandalism, sabotage and terrorism. Based on a proven track record for perimeter protection projects across Spain, Omega Seguridad has also been able to offer its expertise to solar park projects in other European countries like Portugal, France, Italy and now Romania.

The new park is Romania’s largest and also one of the largest parks in Europe and it stretches across 200 hectares and includes some 72,000 photovoltaic panels, amounting to 15 MW of power. The new solar park is said to ensure the need of energy for around 100,000 people.

The total perimeter, including two separate confined areas of approximately 2,1 km, could be covered with a total number of 22 cameras. On average, this amounts to approximately 1 thermal camera per 190 metres. For this particular project, Omega Seguridad relied on FLIR’s SR series of surveillance cameras, offering high quality thermal imaging in any night- or daytime environmental conditions. More specifically they chiefly used the SR-313 camera with 35 mm lens and 320 x 240 resolution, next to the SR-324 camera with 19 mm lens and 320 x 240 resolution. The SR-Series of security cameras provide high contrast imagery optimised to get the most out of video analytics software. In this case, video analytics was provided by Spanish company Davantis.

Antonio Millán Fernández, project manager at Omega Seguridad, explains why his company always makes an extra effort to convince the customer to choose thermal imaging cameras: “Thermal cameras can see much farther than traditional CCTV cameras and therefore you need less of them. So in short: less cameras, less issues.”

According to FLIR thermal cameras also have a higher accuracy and they generate fewer false alarms, which ultimately results in less frustration and less workload for the control room operator. “Obviously, we no longer experience lightrelated false alarms,” comments Vicente Nanclares Ocio. “Sometimes, car headlights can set off false alarms, but since thermal cameras are unaffected by light, they are also not disturbed by it. Thermal cameras also allow us to see better through fog. Sometimes, the fog can be so dense that traditional CCTV cameras are unable to see through it.”

In addition the result gives a significant cost saving compared to traditional CCTV cameras not only in actual hardware but also in power consumption. Although a thermal camera is still more expensive than a visual video camera, the investment cost for perimeter surveillance will still be lower, since you need fewer camera units. Fewer cameras also means that there will be less required investments for all camera-related equipment.
