N-Vision BTS Thermal Biocular


6639 reward points


The BTS Thermal Biocular from Nvision Optics is an uncooled thermal imaging biocular with 2 oculars and one objective, constructed to meet the needs of security professionals and law enforcement officers. The BTS thermal biocular offers excellent performance when used for medium range surveillance such as search and rescue operations, perimeter control, and vehicle identification.

Regardless of the situational ambient light conditions the BTS detects the slightest temperature differences of everything in the field of view. It offers user-defined "white hot" or "black hot" images.

The BTS Thermal Biocular can be powered by 4 included lithium CR123 batteries or it can be connected to an external 12 VDC power source or to AC/DC adapters. Built-in electronics automatically selects the external power when it is available and preserves battery life.
