The LRS1500 is an electro-optical sensor proven on operations with the United Kingdom Ministry of Defence (UK MoD) as a Long Range Surveillance Sensor and is ideal for:-
• Border Surveillance
• Coastal & Marine Surveillance
• Man Portable Covert Intelligence Gathering
• Missile and Test Ranges
The LRS1500 is a high performance long range surveillance system. It provides the observer with the capability to read a vehicle number plate at ranges in excess of 2.4km, to recognize a known face at in excess of 1km and to observe human activity at greater than 8km. The LRS1500 is suitable for operation in remote, exposed situations including coastal environments. The system can be man portable or mounted on towers located at vantage points providing commanding fields of regard.


The LRS1500 is fitted with a continuous zoom lens with a focal length from 12.5 – 750mm, plus a switchable optical 2x extender. This gives the system an effective focal length of 1500mm. This type of lens has excellent light gathering capability throughout its focal length making it an excellent choice for long range, low light surveillance. The lens and camera assembly is encapsulated in a rugged housing, combining excellent military standard EMC qualities with a high level of environmental protection. The front sacrificial glass is optically flat to 1/4 μ @ 750nm. The sensor housing incorporates a wiper unit.


The cameras can be factory configured with daytime colour, or low light monochrome sensors. Alternatively the LRS1500 can be fitted with a unique field proven camera change-over mechanism, providing the ultimate solution for all light conditions. The platform performance can be further extended to include thermal cameras, offering zero light, all weather operation.
The LRS1500 can be integrated into existing command and control systems. Alternatively Cheltek can integrate to single or multi camera control systems.
