I have been looking for a smart, grade 2 certified alarm with police monitoring for some time, and while there are some very good smart systems, and plenty of traditional alarms trying to add smarts, all have significant fundamental issues that mean they are a long way from meeting my requirements. Boundary changes that, or at least, it will. I ordered my hardware and scheduled the professional install without issue, a month's wait, but I was warned of that before purchase. On installation day, it became apparent we had a communication gap between the installation company and me, as the engineer arrived some 4hrs after I expected him, however he was excellent, thorough and friendly so no problem. There were a few issues with the install, that required replacement parts to be sent out, which was done by the ever efficient customer service team, who then walked me through the final steps installing those pieces as the engineer obviously hadn't been able to finish. The system now is good. I think in time, it will be great, which is why I have only given 4 stars. The app is a little buggy, although the main features work fine, and the pairing issues we had at installation feel more like teething pains that I think with time will be ironed out. Also, the police monitoring service option has been delayed... Again. So I don't have that yet either, but again, in time, it will come. Customer service though are brilliant, super responsive and helpful, I trust they will maintain this as they grow. Overall I am happy and I expect in a few versions of the app and some months to get the pro service online, I'll be happy to give it a 5star review.
