Ive inherited a couple of Ajax systems and they seem solid. At some point I’ll set up a demo system to really check them out. Hard to give the impression you actually doing something on an annual maintenance on a Ajax though as no keypad. With an Enforcer you can at least press a few buttons and make some noise. I’m old skool though.
I never install Texecom as I hate their kit, always feels cheap. That said wireless is probably their strongest field. Never used the Texecom app so cannot comment.
