Configuration Notes
The transmitter's Ethernet interface uses a fixed IP address of 192.168.0.215. Configure the connected IP camera on the same subnet and enter its RTSP stream URL in the Web UI.
The transmitter's default frequency range is 200–860 MHz. Custom frequency configurations may be available. Operation at frequencies above 860 MHz may require a compatible external block down converter on the receiver side.
Actual transmission distance and latency depend on the receiver, antennas, frequency, bandwidth, RF environment, and installation conditions.
