I did extensive research on this. Went with the cove home security system. No need for professional installation and they got the best home panel for the price and monthly monitoring is either $15 or 25 a month. And they threw in a free doorbell camera but I already bought the new blink doorbell camera that just dropped this week. I got a blink outdoor wireless cam for the garage, it's supposed to last two years without charging the battery.
Anybody want a good door bell camera for the low DM me
