Hi People, Have not posted here in a long time but I need some help. I am looking to use a new intruder alarm (wireless kit). The Pyronix Enforcer seemed to tick all the boxes, ease of install, features, peripherals, price, tech support and contents of the kit. However, I have asked around a few engineers here in Dublin and they tell me to stay clear because of the app being very unreliable and general end user experience which leads to too many call backs. If you had to recommend any system what would it be and why? Any input or advice would be greatly appreciated. Thanks, Stephen.
