These thermal imaging monoculars are well suited to a variety of tactical, law enforcement, search and rescue, and industrial applications. Both devices utilize passive infrared sensing technology allowing users to detect extremely small differences in the temperature of objects, people and other heat sources within the field of view.

Unlike traditional night vision devices, the TVS 11 and TVS 12C can be operated 24 hours a day, in daytime and at night, even in the total darkness of an enclosed space. Both devices can also see through smoke, fog and other obscurants. Both units feature “black hot” and “white hot” image polarity, while the TVS 12C has additional display colour options including sepia and rainbow. Both units can also be connected to external display devices allowing other parties to view the observed image in real time.

The TVS 11 is designed for helmet, head and weapon mounting as well as handheld use. The TVS 12C is designed for handheld and tripod mounted use.
