The LRS3000 is a completely self contained and highly portable video surveillance, monitoring and recording system. Compact and lightweight, yet powerful and robust, the system has been specially designed for a wide range of demanding long range reconnaissance applications. Employing the very latest in electro-optic technologies, the LRS3000 provides surveillance at extreme ranges and in low light, making it ideal for sensitive covert and overt operations. The system is field proven, having been used extensively in harsh environments.


The LRS3000 electro-optic sensor consists of a fully motorised 250-3015mm continuous zoom Cassegrain lens, coupled to a unique colour and low-light CCD changeover camera. This makes the sensor capable of operating in light levels from full sunlight down to 1 Lux at full zoom and at target distances in excess of 13km.


The camera housing has been designed for special force applications where size, weight and performance are critical. Weighing less than 12kg, the lens and camera assembly is encapsulated in a single, ultra-light housing which combines excellent military standard EMC qualities with a very high level of environmental protection. An equally lightweight and compact, high performance remote controlled Pan and Tilt director head is available. This allows the sensor payload to be accurately and repeatedly positioned onto targets, either by manual control or slewing automatically to pre-programmed positions. An optional fibre optic modem can be incorporated into the base to allow interference-free remote operation over tactical fibre. Cheltek can also provide a desktop controller, a briefcase-style command and control unit or a hand held control unit, all utilising a user-friendly and intuitive Man Machine Interface, greatly reducing the need for operator training.
