FNIRSI Imaging & Sensing

After dark

The NVS-20 monocular and NVS-40 binocular record 4K photos and video in complete darkness using infrared illumination with 6x digital zoom — popular for camping, property checks and wildlife spotting.

Heat tells the truth

The TDM-120 pairs a thermal imager with a full multimeter: scan a board or switchboard for hot spots, then probe the suspect circuit with the same tool. It’s a fast way to find failing components, loose connections and overloaded cables.

Tip: thermal imaging works through darkness but not through glass or walls.
