Vario LED illuminators from Raytec have been selected as part of a bespoke, mobile and solar powered video surveillance system, deployed across locations in Germany.
Security integrator G&G Sicherheitstechnik had received demand for a mobile surveillance solution to provide the detection and identification of subjects at night, from locations which did not have mains power. These included large construction sites, highway and bridge construction, event security, outdoor and open space monitoring.
Good quality lighting was seen as a crucial component of the system, not only so that the cameras could see at night, but also so that the video analytics for the alarm triggers could work to the best of its ability. Furthermore, with the need for a mobile structure, the lights needed to be compact, lightweight but powerful enough to cover the whole site.
“Following testing we chose Vario illuminators to work seamlessly with the other system components,” explains Bernd Gerhards Managing Director of G&G Sicherheitstechnik. “They had the lowest energy consumption and gave 100% reliability even under the worst weather conditions.”
Each system includes three panels of Vario i4 120° low voltage Infra-Red illuminators integrated onto a mobile pole structure along with three dome cameras, a PTZ camera, and a photovoltaic panel to power the whole system – completely independent from power grid.
“The wide angle IR illuminators that we selected easily covered 360° at a distance of 120m, meaning that we could comfortably illuminate the whole site from one mobile structure,” comments Bernd Gerhards. “The system really becomes intelligent when the lighting is used in conjunction with the video analytics.”
The even spread of lighting allows the analytics software to accurately identify subjects on scene and trigger alarms which alert the control centre that the system is linked to 24/7, or the local police. Utilising the illuminators, the bespoke mobile surveillance system can offer a full 360° view, recording and video analysis.
