@Julia9054 Firstly sorry for your rotten luck,it must feel awful when you get burgled.If you are considering CCTV may i suggest you have a look at
this camera setup.We have the 2 camera kit in our house(one each facing the front and rear doors).It's wire free so no hassle wiring it in.All you do is plug the base station into your router via the supplied ethernet cable then press the sync button on each camera and that's it.
The batteries in the camera last ages and it records in HD and has night vision.Then just download the app or log in on your desktop and when you set it to detect movement you get an alert within seconds.
Touch wood we have never had intruders but along with some strong Solidor composite doors,locking windows,burglar alarm and internal CCTV here is hoping it never happens,but if it does i hope we catch the scrote on camera.
