We looked into it, but found it was hard to transmit the signal via the network, plus record. Add in control of zoom and playback and it got too difficult.
We now run a 4k IP Camera at 30fps and a Ubiquiti long range wifi network (AirMax AC). Recording on a SD card inside the camera, plus a NVR back in the clubhouse. The NVR goes via HDMI to the TV.
We also run our gate cams via the same Ubiquiti network, then NVR goes via a HDMI to Composite converter to feed Splasheye that can only handle analogue feeds (disappointingly as it would save some kit and failure modes!).
