The JADE UC is a low cost infrared camera which uses a highly sensitivemicrobolometer focal plane array of 320 x 240 pixels.

The JADE UC camera finds its application in process control, automation and local area surveillance. JADE UC can be remotely controlled by the CEDIP CIRRUS Win software or by the user software for integration into a more complex system.

Outputs are analog video and digital 14 bits video compatible with most third party frame grabber. JADE UC can be connected to the CEDIP ALTAIR software for live image acquisition and processing
