No. There must be adequate separation maintained between all low voltage cables and high voltage cables. This does not apply to fiber optic cables.

I assume you mean can you splice CAT-5 video cable? Yes if it is carrying analog video, no if IP. You should try to maintain the number of twists per inch. Use "beans" or other suitable connectors for the splice and try to minimize the number of splices - each one attenuates the signal.

Hard to say. Maybe yes, maybe no. You would be better going to a regular CCTV or electronics distributor or retailer and buying a name brand.

I have bought many baluns on ebay. Some work well, some do not. It is hit or miss.

If the code allows running fiber in the same conduit it still should not be done. We run a aromored fiber and in all our installs a seperation from hi voltage is specified. You can buy baluns from any number of mfg so I would not mess with ebay. If running underground even in conduit use an outdoor rated cat5 conduits will get moisture in them and you will have your cable sitting in water in a few months.
