The infrared (IR) thermal camera provides night-time imagery, even in total darkness, based on temperature differences. The thermal camera provides a clear video image even under completely dark conditions because it is sensitive to thermal infrared energy. The infrared camera supports continuous zoom to 4X. All M-Series models include a mechanical stabilization feature that improves image stability. The stabilization feature compensates for the motion of the vessel and improves the utility of the camera video output when operating in rough seas or swell conditions. The JCU is your primary method of controlling the camera. The JCU is used to power up the camera or put it in a standby state, to operate the pan (rotation) and tilt movement of the camera, to zoom the IR camera (and on dual payload models, the color visible camera), and to configure the camera settings by means of on-screen menus. The JCU connects to the camera using an Ethernet network connection, and that same connection provides power to the JCU.
