For $40 a month, a three year commitment, and a $125 equipment fee, does the service include armed guard response? If it doesn't you might want to look at www.nextalarm.com before committing to a three year contract. I don't make any money from Nextalarm I just use them along with several customer I have set up with them.
You're right NextAlarm seems to be the value leader.
However, I was reading in the Vonage Forums that some people seemed to have a lot of problems with getting NextAlarm to work properly.
Also, from what I understand, NextAlarm is only via broadband / internet. That's fine for most people.
But I have loved ones, little kids, to watch over, and I have several smoke detectors that are part of the system. I'd rather spend some more money to have redundant paths of communication than save a few bucks a month.
This is why Monitronics is a waste for me - only POTS monitoring for $32 per month. With uControl I get cellular, telephone (POTS or VOIP) and broadband concurrently monitored for $39.
According the tech sales person I talked to, each line of communication is surveyed several times per minute, so that if any line of communication is cut off, I am alerted instantly.
Also, according to the information I have, I have continuous reporting via broadband - so if there are any alarm activity, or internal zone changes, it's reported real time on the uControl website to me.
So yes I know it's a lot more pricey than NextAlarm or DollarAlarm or the other derivatives, but for redundant paths of communication and constant communication, I think that the extra money would be money well spent.
