I’ve got the enforcer and it’s a good alarm and not to difficult for a diyer to configure. The app is a bit crap though and you have to pay £35 a year to use the app. Sometimes when the alarm goes off the app doesn’t even notify you.
Thanks for that, the app was one of the appealing factors. I've heard it works better on iPhone which is unfortunate.
What issues do you have with the app other than notifications?
The newer ProControl+ app is much better than the original and can also be used for cameras too (Hikvision) the yearly subscription is for the secure cloud based service.
