Ta Chaps,
What I was thinking of would be to set up the DVR in the garage and run the cables from there to the cameras, the ones on the outside of the garage would be fine, but to get to the front of the house would probably need about 50m of cable and most sets only come with about 20m cables.
Is there a solution for that that doesn't involve wireless cameras?
Once set up I would leave the DVR in situ and remove the screen preferring to access the system remotely, but is there a DVR on the market with a wireless access to a router or a suitable dongle/adapter?
The only alternative would be to run a network cable to the router which I want to avoid as the whole house has just been decorated and the idea of putting the DVR in the garage is to avoid cables in the house.
