Thermal night vision cameras

November 2012 CCTV, Surveillance & Remote Monitoring

The new FLIR LS-Series thermal imaging camera provides the power to see clearly in total darkness. It gives law enforcement officers, security patrols and any other person that needs to see at night, the information needed to make critical decisions, enhance mission effectiveness, maximise operational capabilities and improve safety.

The FLIR LS-Series is affordable. Price is no longer an issue, from now on; every law enforcement officer can be equipped with thermal night vision. It is equipped with an uncooled, maintenance free, microbolometer detector. It delivers crisp thermal images in any day or night situation. The FLIR LS64 produces thermal images of 640 x 480 pixels. Users that do not need this high resolution can choose the LS32 which produces images of 320 x 240 pixels. All cameras are equipped with advanced internal camera software that delivers an image without the need for user adjustments.

The FLIR LS32 comes with a 2x digital zoom, while the FLIR LS64 is equipped with a 2x, 4x digital zoom and continuous electronic zoom. The LS64 is equipped with a 35 mm lens. It allows detecting human targets at a distance of no less than 1080 metres. The FLIR LS32 is equipped with a 19 mm lens that allows detecting a human target at a distance of 640 m.

The series comes with long-life rechargeable Li-Ion batteries offering a typical operating time of 5 to 7 hours on a single load. Weighing 340 grams, batteries included, the FLIR LS-Series are compact and light systems. They are ideal for go-anywhere operations, in all circumstances. They are IP67 rated and operate between -20°C and +50°C.

Easy-to-operate

Ergonomic and easy-to-use, FLIR LS-Series cameras are fully controlled with the buttons on top of the unit. Conveniently placed the buttons are all right underneath your fingertips.

Laser pointer

Both versions of the FLIR LS-Series come with an integrated laser to quickly and safely pinpoint suspects in the dark.

InstAlert

The unique InstAlert feature colours the hottest part of the scene in red, making it easy to spot suspects in the thermal image.

Thermal imaging versus image intensification

Image intensification, also referred to as I² technology, amplifies small amounts of visible light thousands of times so that objects can be seen at night. Image intensification does require a certain level of ambient light, but even starlight can produce an image on a cloudless night.

Because the system requires at least a minimum level of ambient light, conditions such as heavy overcast can limit its effectiveness. Similarly, too much light may overwhelm the system and reduce its effectiveness.

Thermal imaging cameras like the FLIR LS-Series offer substantial benefits over image intensification. They work by detecting the heat energy being radiated and need no light at all to produce a clear image in the darkest environments. Thermal imaging cameras are not affected by the amount of light so that you will not be blinded when looking at a light source.
