hi there, looking to get a wirless alarm (as i figure its the quickest and neatest to have fitted given the house isnt wired for one already) out in a 2 bed house im buying. now i don't know much about alarms (i did use the search and read the key posts etc! but am still confused) and all i'm looking for is the most basic set-up. we've an alarm (non wireless) in our family house and it doesnt have any of this fancy call monitoring stuff - is this really essential?? also iv checked out some of the installers listed and they dont seemm to do wireless??? is this because they are ultra expensive and/or specialist?
many thanks!

many thanks!
