An infrared (IR) camera includes a camera unit for recording IR images, a slave monitor connected to the camera unit for displaying IR images recorded by the camera unit. In this way, the camera unit can be moved independently of the operator. The slave monitor is preferably connected to the camera unit via a cable, a short-range radio connection or a Wireless LAN (WLAN) link. The connection is used for communicating image data from the camera unit to the slave monitor as they are recorded. The connection may also be used for control data from the slave monitor to the camera unit.
