I'm afraid that the cameras might not work properly since it supports up to 270ft cat5 cable and 330ft cat6 cable, for regular PoE transmit distance is 260ft maximum, but you can add 1 booster on each end and a outlet to plug a power supply into. It can extend pretty far.

If you integrated these NVR with your cameras through you home router and have the app, it should work fines, you can remotely access anywhere

You need an ethernet connection and you need either an NVR with PoE (power over ethernet), a PoE injector, or a PoE switch. You have lots of options.

22. How can I mount these cameras ?

A: You can mount straight into the wall, ceiling, or whatever you're mounting it to. If you don't want the wires exposed, you'll need some type of riser or wire molding. And there's a screw cap to cover the connector so you don't risk water intrusion. You can also recess the connection into the wall or ceiling.
