There's been a few break ins locally where thieves have broken in whilst people have been in and threatened or assaulted them to give up valuables. So for peace of mind I'm looking at how to improve our home security. I have CCTV cameras and I have a Ring doorbell which should create a decent deterrent. So looking to add another. So recommendations on an alarm system with visible outdoor siren that has door entry triggers and a notification system via wifi (as I don't have a phone line). Thanks.
