The standard remote control system can be expanded to support the real time video streaming function. Up to three video cameras and a device called Video Transmitter (VTX5) are installed on the equipment under control. An environmentally-protected tablet is attached to the TC5 and held by the operator. This system allows greater distance between the operator and the machine, thus enhancing safety and comfort. The video feedback is sent over the WiFi link to the tablet, and the maximum operating distance is about 150m.
