Thanks. I did look at the Response alarms, similar to the Yale kit I got and they had a Solar array on the siren box. I read some reviews that solar array on the lid wasn't reliable enough for recharging the batteries. I am sure there are other things out there, but probably outwith my initial budget. When buying a new house, funds for the first few months are limited. So had to get an affordable alarm system that I could install in the first month of moving in. I know burglars do target new build houses as its easy pickings for them. Chances are high for no alarm system and most people still have items lying about or in boxes. Easy grab. My folks house fell victim to this in 2000 (new build but in it for 2 years). This triggered them to get an alarm installed. Fingers crossed I dont become a victim of house burglary, even though it has happened to me before in a student flat.
