Security Services are a fantastic security company? with Great cameras!!! I have purchased loads of cameras from this place and I have had no problems since I have installed them! I also use Static guards from a place called Security Guards UK witch is based in wolverhampton there guards are excellent and highly recommend by myself check them out :) both great companies!
Having just been burgled, I decided to install a burglar alarm, and the best I could find for the money, was the Response RE5000S. This alarm retails at about £170. The 5000s is a wire free system, so installation is very much a piece of cake. You just screw the keypad to the wall, screw the sensors into place, put the siren/strobe on the wall outside and away you go. The alarm is zoneable, that is, you can set each sensor to be part of a zone ( zone 1 upstairs, zone 2 downstairs, zone 3 garage etc) and you can "part arm" the system if required, such as arming the downstairs zone but not the upstairs one when you go to bed. ( saves setting the alarm off when you get up in the middle of the night for a pee. In the box you get the keypad, one remote control,one siren/strobe unit, one Passive infra red detector and one door/window magnetic sensor. I opted for extra PIRs and magnetic sensors, along with an extra remote control. These cost about £17 each, but are easily obtainable, and simple to install. The only thing you may have a bit of trouble with, is setting all the programmable functions. Having said that, the manual is excellent, and easy to follow.
