I went from POTS to an internet monitoring solution that was not reliable, and switched to the Telguard Express, but that raises my monthly monitoring from $10.45 to $22.45, and I get no increased functionality. I had tried an HAI unit in between, it proved to be incompatible with my panel and in general not of high quality.
I like that the CBAT provides both IP and cellular - but I can't find any info on a) who keeps the minutes full, b) if there is a charge to access it remotely or c) who that access is through. One concern I've always had with IP monitoring is any ability to access my system remotely gives me vulnerability. With cellular monitoring there is no ability to do that, but with IP if you have the ability to arm/disarm via IP then the ability exists to hack the system.
Edit - in communicating with the company today, I found out that your alarm company keeps the minutes through, and handles the interface - and whether you pay any more (yes) for that. So, while it gives remote capability and IP as well as cell, no free ride here.
On another property I had to put a system in quickly and went with a Simplisafe. Totally wireless, prices ranging from $14.99 to $24.99 per month for the level of remote access you want, and no contract. Downside - the sensor batteries don't last anywhere near as long as they say, and when you are remote it's not fun to learn that a sensor isn't responding and it's several hours away. Upside - you can remove that sensor from triggering a false alarm and just have it send a text.
I would not consider letting GV communicate alarm signals, and frankly not any VoIP service. Too unreliable.
