Solar farms are systems of solar photovoltaic panels that often cover large areas of land in rural areas, which makes essential to place effective perimeter protection. The Company GJD was commissioned to manufacture reliable security lighting to work in conjunction with the video surveillance system at a solar farm in Cambridgeshire to provide optimum security.

The farm required an intelligent detection lighting and video surveillance solution for a 13MW PV installation. Key specifications for the project included reliable security lighting, even in adverse weather conditions, precisely angled lighting and up to 95 metres lighting range. Given the type of the project, it was also very important that the lighting selected had very low energy consumption without compromising on quality or efficiency.

GJD worked closely with AGE CCTV Systems and the solar park project manager to select the most suitable security lighting. After careful consideration it was decided that the Infra-Red Clarius® IM illuminator was the perfect lighting solution as it is specifically designed to provide world class leading performance, long lifetime and ultra-low maintenance.

The director of AGE CCTV Systems Gary Whiteman commented: “AGE choose Clarius® LED illuminators from GJD to complement our CCTV system as it provides competitively priced, high performance LED lighting in a rural environment “.

Combining surface mount LEDs with enhanced optical output and excellent reliability, the Infra-Red Clarius® IM illuminator enables high quality night-time images and works in conjunction with black and white or day and night cameras to emit light invisible to the human eye, but fully visible to the video surveillance camera. Each unit is installed with integrated control circuitry to carefully control the LED output, so it emits a uniform illumination for the solar farm and it is designed to have an operational lifetime of over 10 years.

Since a video surveillance device depends on reflected light, surfaces that have a higher reflection coefficient will allow the device to display images better. More light is needed to reproduce quality images near dark surfaces (e.g. asphalt) than to lighter surfaces (concrete). It is highly recommended to replace old lighting with LEDs and depending on the type of cameras being used, white light or infrared LED illuminators can be added.

GJD’s Clarius infrared LED illuminators, marketed by Bunker Seguridad Electrónica S.L., work in conjunction with black and white or day and night cameras. Their advanced technology provides uniform and constant illumination, maximising camera performance and ensuring high quality images. In addition, they have a long service life and very low maintenance.

Elliptical beam profiles allow more light to be delivered to the area where it is needed, so distances can be extended and the waste of light minimised. The system also helps to avoid overexposure of foreground objects. The interchangeable lens diffuser kit allows the user to quickly and easily modify the illuminator’s field of view to suit the camera.

The Clarius® Plus IP is a high performance infrared illuminator incorporating the latest surface mount LEDs with enhanced optical output and exceptional reliability. The night-time images obtained with such assistance are of high sharpness and quality, while the devices hardly suffer any changes over time, thanks to the CleanLITE® technology of the lens coating that provides self-cleaning and improves the device’s resistance.

The images captured and recorded by a camera in a well-lit environment are truly extraordinary. On the other hand, LED illuminators are often used to deter intruders before they attempt to access to a protected site.

Another important part of an effective video surveillance system is intelligent video analytics that can be used to reduce false alarms, make detection more automatic and intuitive, and facilitate the work of security professionals. It’s about getting the right information that allows you to act before incidents or losses occur.

Over the years, numerous studies have examined the effectiveness of individuals monitoring multiple video screens. The results indicate that alertness and concentration are reduced after more than 15 minutes of continuous monitoring.  The use of advanced video analytics algorithms makes the video surveillance system more effective and adds automatic real-time actions. When choosing a suitable security system, it is often necessary to take into account the existing detectors in the perimeter detection system.

The solutions that we recommend are those of the Tempos Analytics brand, which are configured in a very intuitive way to adapt to different applications and sites and at the same time complete the system of warnings and actions. They include the possibility of interacting with the detectors of your perimeter system, either through IP OPTEX integration or through I/O modules.

Both, LED illuminators and video analysis systems with advanced algorithms can significantly improve the detection of a video surveillance system and reduce false alarms.

This is a very important tourist complex that clearly needs to be protected from vandalism in order to ensure its perfect preservation for as long as possible.

So, in early 2013, Wessex Fire and Security was responsible for project managing the supply, installation and commissioning of the fire and security systems for the new Stonehenge visitor centre. Three buildings comprised the new Stonehenge facility: the main visitor centre, an ancillary building (for all plant, vehicles and machinery) and a security centre/post (the old visitor centre).

Stonehenge required a sophisticated, high-end perimeter detection and security system.

GJD worked closely with Wessex Fire and Security to manufacture and install the new security system for the Stonehenge site.

The use of GJD’s Clarius® infrared LED illuminators fulfilled an important requirement for the project, as verification of the process was carried out using a video analysis system. It was therefore necessary to separate the cameras from the infrared sources to minimise the attraction of the insects to the cameras. Different alternatives were studied and finally GJD was chosen because of its quality and previous experience.

Stonehenge required a sophisticated, high-end perimeter detection & security system and Clarius infrared illuminators were perfect for these needs as they work in conjunction with black and white cameras, day and night, providing a light that is invisible to the human eye, but fully visible to the CCTV camera.
