Portable thermal device for aiming and surveillance MEDVED' is designed to detect targets within vast areas in difficult meteorological conditions at a high level of natural and other interferences: fog, snow, rain, smoke, dust, and blind light. This type of device can be used as a sight for firing from a weapon of normal caliber for a distance from 300 to 800 m, the range of firing depends on the size of the IR matrix and the characteristics of the lens used in the device.
