will this work with RLN8-410?

Yes. The specs on the RLN8-410 list the 8xx series cameras.

Is this a wireless camera?

No. If it says PoE and that stands for Power over Ethernet. It works best with a network switch that has PoE ports, but it can also be powered by a 'wall wort'. The reasoning is that with PoE you only run a normal Ethernet cable to it, and that cable provides both power and networking.
