Spec me a CCTV System

[radderfire]

What I'd like is alarms on external doors doors/windows being opened, that alerts some main box which has a noise, and then also our phones. This would be self setting and done between say midnight and 6am.

It's not a recommendation because I don't have these products, but something for you to look at:

Ajax and Eufy are quite well known for security systems. There might be a thread on home alarm systems on here too, but I'm not sure.
