The common camera is an equipment of visible imaging. Its image-forming principle is based on the difference between reflect and reflectance on the target surface. But the infrared thermal camera is different totally, it utilized the thermal contrast difference between targets and surrounding environmental conditions to forming the thermal radiation energy density images,
we call it as "thermal imaging". As same as light wave and radio wave, the infrared radiation is a kind of electromagnetic
JH640-280 miniature cooled thermal camera utilizes third generation HgCdTe 640x512 MWIR focal plane arrays (FPA) detector. The detector transform the target thermal radiations to electrical signals, after the process of a detailed analysis of electrical signals on image processing circuit boards, detector output analog and digital video signals together; the host PC control the thermal camera via RS422 communication interface.
Features
JH640-280 cooled thermal camera is a matured and high reliable product developed by our company independently. It utilizes high-quality material and top-end manufacture technology. The thermal camera is featured by small size, high sensitivity, easy to control, long surveillance range, all weather operations and easy for integration. It adopts high sensitivity MWIR detector and 640x512 resolution for crispy
image. In addition, continuous zoom lens 15~280mm can distinguish the human, vehicle and ships at long range.
