SOLO Monocular Handheld Thermal Imager

A one-hand 384 x 288 / 640 x 512 thermal observation platform with integrated 5-1000 m laser rangefinder, electronic compass and geo-tagged recording for search, identification and field evidence.

Product overview

SOLO uses a 12 um VOx uncooled detector in 384 x 288 or 640 x 512 resolution with 25 mm or 35 mm objectives, and offers white-hot, black-hot, red-hot and fusion image polarities. An integrated 5-1000 m laser rangefinder, electronic compass, picture-in-picture and 1x/2x/4x digital zoom support search and range confirmation, while photo and audio-video capture with Wi-Fi app transfer covers field recording. A single removable 18650 battery delivers about 6 hours of operation, and IP67 sealing handles rain, dust and field use.

Problems addressed

Targets are hard to spot by eye at night, in dust or against clutter; Range estimates lack verifiable measurement data; Field records lack position and time metadata for a complete evidence chain; Carrying multiple devices is burdensome; a one-hand observation tool is needed
