Brivo panels are a joke. We've heard stories about how the door was suppose to stay locked in the morning until somebody shows up, but the employees would show up to find that the door already unlocked with nobody at the office. This happened several times. It took a while to find out that there was a bug in their code. Who knows what other bugs do they have.
They act like a startup, and have startup kind of bugs. You're better off with a more established company that has more rigorous testing process. Last time I checked, they don't even employ any hardware engineer. Kind of scary considering they manufacture the control panels. Oh well. Just MHO.
