Portable thermal imaging cameras for security and law enforcement applications


The BHS-Series are shock-resistant thermal imaging cameras. They produce a crisp image in the darkest of nights. With the BHS-Series security professionals and law enforcement officers can see suspects in total darkness, through smoke, and light foliage.


The BHS-Series are bi-oculars. This means that it is less tiring to use for the eyes than a monocular. By using a bi-ocular the ability to detect faint objects is enhanced. This means that you have more chance to detect small objects against the background. It is also easier to hold bi-oculars steady when looking at an object. An advantage if you are looking at small things which are far away.

The BHS-X is equipped with an uncooled vanadium oxide detector. This provides excellent long range viewing with sharp 320 × 240 native resolution in the viewfinder and a 2× digital e-zoom step to 160 × 120 resolution.
Powered by FLIR’s 640 × 480 core, the BHS-XR delivers greater range performance with crisp, clear 320 × 240 native resolution in the viewfinder AND while in the 2x digital e-zoom mode, plus an additional 4× digital e-zoom step to 160 × 120 resolution. Full 640 × 480 resolution imagery from the BHS-XR Series is also accessible via the «aux video» jack in the hot shoe.


lenses  The BHS-Series can be ordered with different lenses. Longer lenses have a narrower field of view and allow you to see targets farther away. Lenses are interchangeable. The specific lens(es) you require for your application need to be specified at time of order.
