Don't want to be a killjoy but it's very rare you will find the socket ring in the loft - Sockets normally go down the wall & under the floorboards. Could you not take a socket off the wall & see if you can run the cable up to behind the Tv as well as down the wall from the loft for the Aerial...
As long as you have 12vDc - 13.5vDc & 500Ma per camera it shouldn't be a problem.
On another note - Are the power supplies located near the camera? Could you power the camera near to it's location & just run the coax back? This way the power is only a short run and would eliminate a power drop.
An in-line filter for Cctv Coax is known as a "Humbug" - Most cctv suppliers should stock them. As stated they just plug in-line with your coax.
With regards to the power running with coax - If the camera's are 12vDc this shouldn't be a problem as "shotgun" cable is made this way for cctv...
