I've had these cameras for a month, and they've worked correctly maybe 3 or 4 days. I've been in contact with their tech support twice. The first time we had to pay the 3 year subscription to change our router. Called again today because we are not receiving any notifications and the batteries run down in 4 days. So, $500 for the cameras, $250 for a 3 year subscription 2 months before our trial expires. Guess how we are feeling?
