FLIR Scout III 640

The FLIR Scout III 640 Wildlife Thermal Camera is a powerful thermal imager that has several applications in outdoor activities such as game tracking, camping and hiking. The high-resolution 640 x 512 pixel thermal sensor offers extremely clear imaging and can detect heat patterns from animals, people and machines from a distance of 1140m.

A live thermal video is shown on the 640 x 480 pixel monocular LCD display with a 30Hz refresh rate. The field of view measures 18˚ x 14˚ and the user has a choice of colour palettes: greyscale, InstAlert and graded fire. The FLIR Scout III 640 has a 4x digital zoom and a thermal video output allows the user to show images on a monitor or save them to a recording device.

The FLIR Scout III 640 is very easy to use and has a rapid startup process which means there is no need to keep the camera on standby, thus saving the battery. A fully charged battery will usually last for over five hours so the imager is a reliable tool for a day without access to electricity.

An IP67 ingress protection rating means that the FLIR Scout III 640 is fully submersible and can withstand the knocks of regular use. It is supplied alongside a wrist strap, video cable, USB charger and MOLLE bag.
