I have been a customer of suretyhome for years. I had the 2 gig vivint panel. they instructed you to swap out the board ( easy do it yourself) and everthing was connected to them for a LOT less. And best of all, you can do changes yourself. It was so easy to program and reprogram sensors. You can buy equipment from them or buy/bring your own including ebay sensors.. They all connect to alarm.com. They give you the option of central monitoring and having them connect to fire/police. However, as our door sign says, 'We don't dial 911". I think you will find the advice here on cams far superior. I dont use Alarm.com cameras.
