Here are a couple of comments
If you go with digital transmission like 2.4 ghz the issue you will find is that the quality in low light will not be very good, the compression system goes crazy with the grain and low light
Wiring up a distribution network is fine, if you have the time, budget and access, the simplest is to just encode to rf and use standard tv's for the most flexibility get a frequency agile modulator like Blonder Tongue, then you can select the
channel easily
Another alternative to explore is

It is a a sender that uses standard channels, basically a low power tv transmitter
