One of the latest developments of the Shvabe holding company, SOSNA Scanning Anti-Surveillance Detector, is a unique device with no comparable counterparts in Russia. It automatically detects and locates optical and optronic counter-surveillance aids at a distance of up to 2,500 metres.
SOSNA is composed of a scanning probe and a control board inside a heavy-duty enclosure. Weight of both components is 3.8 and 4.7 kg, respectively. With a total weight of 8.5 kilograms the device has an integrated battery capable of three hours of continuous use on a single charge. The device may be connected to a standard power supply source or an on-board electrical system of a car using special adapters. The working temperature range of the device is minus 25 to plus 45 degrees Celsius.
The device uses a narrow-directed 6-20 degrees/second infrared laser beam to automatically scan the area. The scanning angle may be adjusted by ±180°. The system's laser beam is capable of detecting optical aids such as binoculars at a distance of up to 2,500 metres.
When detecting such aids the device generates an acoustic signal and automatically records the detection time, target's coordinates, azimuth of target and time of surveillance. The device memory can memorise up to 3,000 colour images of the area with geolocation markers.
It can also memorise flaring spots, i.e. false targets: during the next scanning session it removes them from the field of view.
As was noted by the developers, the device is primarily designed for prevention of attacks on military and civilian facilities. Due to its portability the system may also be used to guarantee reliable personal security or to ensure safety of various city events. SOSNA detects intruders as early as at the preparation stage as any attack on any facility always means a preliminary study of its vulnerabilities in a covert surveillance mode.
