I left a review a few months after installing my Boundary Alarm System and now I've had the system and have more experience I thought I'd update my review. Overall the alarm is very easy to set up and install and works from the App. I did have some problems with a contact sensor I fitted to my garage but a few messages to the Support Team and they sent a Z Wave extender which partially solved th problem. After a couple more months we noticed the garage sensor kept dropping off the system and some other sensors were trying to connect to the extender and not the hub so again, a few messages to the support desk and they ran a few tests, identified which sensors were not connecting properly and agreed another extender for inside the house should fix the problems. They also swapped the contact sensor in the garage for a motion sensor (this was my fault for fitting a contact sensor my garage which is detached from the house and has a metal door. Another signal test by the support team has confirmed all the sensors are now connecting properly so I will monitor how things go and report back in a few months. Overall my experience with Boundary has been positive. Any teething problems have been swiftly dealt with and the regular software updates continually improve the system. If you're look for a quality alarm system that you can install yourself (if you don't want it monitored) then I'd highly recommend a Boundary System.
