There are a lot of negative reviews here, but once they got the initial kinks worked out with my system, I’ve had zero problems with it. There were several “timed out” issues right after my new security system was installed, but the company made some adjustments at the panel as well as on their end, and since then it has worked flawlessly. My home is still under construction, but we were able to get things up and running and it’s terrific knowing what workers are coming and going, and what time they arrive on the job etc. It’s great getting notifications on my phone whenever a door is opened or when someone forgets to lock up, and so convenient that I can lock everything remotely on my phone. Works great for me.
