BHM-Series are shock-resistant thermal imaging cameras. They produce a crisp image in the darkest of nights. The BHM-Series will dramatically increase your situational awareness. The BHM-Series can be used on board of all types of vessels. Yachts, commercial ships, tug and tow boats, work boats, police and law enforcement boats will all benefit from the power of thermal imaging.

The BHM-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 BHM-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 BHM-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 BHM-XR Series is also accessible via the "aux video" jack in the hot shoe.

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

The BHM-X comes with a 2x digital zoom. The BHM-XR has both a 2x and a 4x digital zoom. This allows you to have a closer look at the situation when necessary.
Weighing just under 1000 grams, batteries included, the FLIR BHM-Series are compact and extremely light systems. They are IP66 rated and operate between -20°C and +60°C.
Ergonomic and easy-to-use, the BHM-Series are fully controlled with just 5 buttons on top of the unit.
Just press a button and start recording thermal video on a removable SD card.
Both versions of the BHM-Series allow to store thermal images in JPEG format on a removable SD card. Images can be used as evidence.
The battery compartment holds 4 rechargeable AA NiMH batteries. Good for 4 hours continuous operation. The BHM-Series can also run on standard commercial off the shelf non-rechargeable Alkaline or Lithium Ion AA-batteries.

The BHM-Series come standard with a “hot shoe” which can easily be attached to the camera. It allows to charge the camera and connect the camera to an external video monitor while the camera is mounted on a tripod.
