If a cable connection is no suitable solution, a radio transmission of the image signals is possible. We usually use this system for the lanes or danger spots. The camera and the transmitter are firmly attached. Any number of vehicles can be equipped with a receiver and a monitor. The receiver is connected to the monitor by cable. The transmitter, connected by cable to the camera, is mounted on the fork carriage with a replaceable battery (operating time approx. 8 hours). Transmitter and receiver are protected to IP68. The radio transmission operates in the 2.4 GHz range and there are 7 channels available. It is important to clarify if other radio systems in the room can not cause interference.
