RTSP over TCP and UDP

This is especially important for direct RTSP mode.
The SysDVR server supports two modes: TCP and UDP, this usually doesn't matter but I've found different programs will connect using different modes, eg. mpv will always use TCP while obs will try UDP first and then TCP. Depending on your network environment you can find one to perform worse than the other so you'll have to test which one works best for you.

In mpv you can force udp mode by running mpv rtsp://<SwitchIpAddress>:6666/ --rtsp-transport=udp.

Streaming setups

The best streaming setups i can think of, from best to worse, are:

1. Switch and PC directly connected to each other via lan. For this to work you'd need to host a dhcp server, your own 90dns instance and a server to spoof conntest.
2. Switch and PC connected via lan to the same router.
3. Switch connected to a near 5GHz router and PC connected via lan.
