I have noticed that there has been little mention of the 2GIG GC3 security panel, which I highly recommend. A year plus or two I was seeking advice here about panels when I was so disappointed by the ancient options that seemed to be available. You were helpful, and I wanted to pass along what I've found to work well.
The GC3 has a large and beautiful capacitive touchscreen, integrates well with Lutron RR2 (and Caseta), features Z-Wave PLUS for other automation, has WiFi to be unlocked in the future, has everything in one package so you only have to run power, supports 2-Way Voice etc. At my house I put in garage door opener controllers and from the same app (or Apple Watch app) I can change Lutron settings, open or close garage doors, arm the system etc.
I liked it so much I decided to become an alarm.com dealer and 2GIG installer to add to my RA 2 business.
You'll see the panel below, which is both the touchscreen and the security panel all in one unit. While not all the outputs are currently active (RS-232, for one), I run them to a basic patch panel shown so that no more wires will ever need to be run. I run them into VCRX for smoke lighting in case of a fire and full/flash for alarm. The pic of the panel doesn't show this wiring, but I'd be happy to send pics.
