There is an expanding requirement for coastal surveillance both as a means of countering potential terrorist threats and for border intrusions and this requirement can extend to monitoring wind farms and other offshore installations.

With very few manned coastal observation stations now operational, the use of remotely controlled equipment for monitoring offers a viable option. To meet this requirement, British company Chess Dynamics has developed their Sigma LEO.

Sigma is designed for long range coastal and border surveillance and is optimised for remote detection, identification and image and/or video capture in all types of border and coastal surveillance locations. It is configured as a sub system module that forms part of a multi node integrated surveillance system that allows for long stretches of coastline to be monitored. It requires a simple power supply and an Ethernet interface to enable the transmission of images over long ranges by wire, fibre optic or a wireless communication network.

“Long range vision on borders and coasts is critical for a security force tasked with keeping either an asset such as an offshore platform or a coast line secure. We have developed the Chess Sigma LEO with extended range, video analytics, high reliability and fault tolerance to meet the most stringent remote operations while reducing both operational and support manpower,” commented Dave Eldridge, the Sales Director of Chess Dynamics.

“Together with our colleagues at Vision4ce, which is a Chess Technologies company, we have developed a system which can automatically analyse imagery and send only altered data back to a command centre many miles away,” added Mr Eldridge. “The system can also self-monitor and, with dual redundancy built in, can complete an element of self-repair, thus reducing the need for a person to visit the site for first line repairs.”

The processing unit at the heart of the Chess Sigma LEO has been designed to carry out many tasks remotely which are normally done at the command centre.  These include automatic target detection, analysis and tracking, optimising the tracking point and sensor field of view, capture of multiple still images and video recording of both identified and unidentified targets including backup storage and overall system monitoring.

The unit is designed to be ‘sensor agnostic’, enabling the user to select the most effective EO sensor configuration for their specific task. Low light TV and infra-red detectors are available and the range is up to 10 nautical miles when mounted on a 30-foot-high mast and at this range the outline of a container ship could be detected. Built into the design is high reliability coupled with low maintenance requirements, to minimise the need for staff to travel to the remotely deployed units.
