What are the range limits of Power over Ethernet?

I want to install a security camera on a wall about 50m from my back door. I intend to use Power over Ethernet as a power source. I have no experience with PoE, and have some questions.
From the research I have done, I think the answers to the questions I have are all 'yes' but it would be useful to have that confirmed by someone with more knowledge:
- is 50-60 m within the maximum range of PoE?
- I already have CAT6 in the house and would like to be able to bring the signal from the camera back to the network equipment under my stairs, so there will be two lengths of cable involved - one inside the house, from the central location to the outside wall (about 10m) and one outside (about 50 m), connected via a standard RJ45 connector and socket. Am I right in thinking that this makes no difference?
- Can I send data and power over the same line? Is there anything that I need to when running the cable, wiring it up or selecting equipment (such as a PoE switch) to enable this?
If there are any other issues that I should be considering, please let me know.
