FLIR LS32 Thermal Night Vision Monocular

The LS32 thermal monocular is the most compact and affordable Law Enforcement imager to date. This unit features a 336 x 256 pixel detector, a maximum range of 600 yards, and a lightning fast 30hz refresh rate.

The FLIR LS32 thermal monocular hits the perfect balance between size, cost, and ability. This unit can be carried anywhere, and has the range to make it widely effective for officers in the field.

FLIR LS Series Thermal Night Vision

Thermal Night Vision in the Palm of Your Hand

Built on FLIR's smallest chassis, the LS32 uses a USB-charging internal lithium-ion battery and features a one-handed, four-button operation. The display itself auto-focusses, but a diopter adjustment on the eyepiece ensures you get the sharpest image for your eyes.

The LS32 can display different polarities to fit varying situations and environments. White-hot and black-hot displays are the FLIR military standard, but you also get 4 levels of Instalert™ polarity, which will isolate subjects above a certain threshold and highlight them a bright red.

The LS32 can also zoom the digital image 2x to get the closest view and furthest range. When you're pushing out to detect: the 2x magnification makes it easy to pick out even the smallest hot-spot.

This unit also features an internal targeting laser to indicate heat signatures for officers without thermal devices.

Features 4 Night Vision Modes

FLIR Night Vision Will Help You:

  • See people - keep track of the rest of your hiking or camping party in the darkest nights, and even when they're obscured by light foliage.
  • See animals - everything gives off heat, so animals can't use their natural camouflage to hide from Scout. Discover those hard-to-spot animals that you've always wanted to see, day and night.
  • Track game - sportsmen can use Scout to track wounded animals by following their heat signatures directly, or by detecting signs they leave behind like blood trails and foot prints.
  • Navigate - no more losing the trail at night or in bad visibility; with Scout, you'll be able to navigate just as well at night as you can during the day.
  • Stay safe - Scout's thermal night vision technology lets you see clearly through smoke, dust, and light fog so you can stay safe in the outdoors when conditions deteriorate.
  • See more, and see farther, than with other night vision technologies - because Scout sees clearly without any light whatsoever, it can see farther at night than other imaging technologies that need ambient light to work, and can see heat sources that these other cameras could never find.

What is Thermal Night Vision?

FLIR thermal night vision uses infrared radiation to build its image, which means it sees heat not light.

This means that thermal night vision highlights temperature differences in the scene its interpreting. That makes FLIR the pinnacle of detection. When it comes to spotting the odd part out in a scene, even in total darkness, thermal differentiates like no other technology.

Because it's seeking out temperature differences and heat signatures, FLIR cameras can be just as useful in daylight as they are at night. In low contrast environments, heat will still be a differentiator regardless of any camouflage. This also works at long distances where your eye may not pickup a distant object. A FLIR camera will highlight that far off heat signature, even if it's just a cluster of pixels different.

Reading infrared radiation also means that these units are not blocked by the kind of things that might interfere with our vision. Particulate obstacles like smoke, dust, and fog have a much smaller thermal signature, and so the FLIR camera can see right through them. Even snow and rain to an extent will have less of an effect through thermals than they would on your naked eye.
