The Cairns Fire Camera utilizes a Microbolometer detector that processes thermal radiation in the 8.0 to 14.0 micron range of the electromagnetic spectrum. Thermal sensitivity of the system is better than 0.07°C (.13°F) with a nominal dynamic range of -30°C (22°F) to +150°C (302°F) without the use of an iris or restrictive aperture.
The Camera has a high resolution (76,800 pixel, 320 columns x 240 rows) full-motion video image (60 hz NTSC or 50 hz PAL) without jutter. The Image is void of black halos, banding, white-out, blooming or significant artifacting when viewing hot objects. Colder objects are displayed as black shades. Hotter objects displayed as white shades. Highly radiant energy displayed in two stages of yellow and red (for greater than approx. 480°C / 900°F).
The Cairns Camera a IR field of view of 60° horizontal x 45° vertical (75° diagonal) that is automatically in focus between 1m (3.28 feet) and infinity.

The Camera is ergonomically designed to be gripped from above or below, with the left or right hands. Handstraps are designed to fit gloved and ungloved hands. Adjustable length, 2” wide neckstrap to attach via quick release buckles to the Camera. Camera to have a slim (92 mm, 3.625 in) profile to permit access to confined spaces. All straps have non-metallic hardware to reduce risk of burn to unprotected skin.
For simplicity of operation, the Camera has only one ON/OFF control switch operable with a gloved hand. The switch is protected from inadvertent operation.
The Camera will operate in conditions that are normal and expected for fire and emergency services. The Camera meets the following heat and flame criteria, without loss of function:
Extreme Heat & Flame Resistance NFPA1981, Method 3-11.1 to 4-11.1
