Not really decided on wire free or wired yet... I guess both have their pro's and cons, right?
I basically have 3 door access points downstairs (Front door that has a small laminated toughened glass window, and a side panel that has the same, patio door in the lounge and the back (kitchen) door), plus a detached garage that I would ideally like to be included, plus 2 windows downstairs that would need to be included. With regards to upstairs, there are potentially 6 windows. I fear this could push the price way above my budget though!!
