Most of you have small businesses or homes that probably went to a system for monitoring. I am looking for a wireless, no contract home security system to monitor just a door and a couple of windows shielded from the road that would grant easiest access, to also include water sensors in case of sump pump failure or hot water heater puking, and if there is a furnace failure resulting in low temps. My research to date has the Notion All in One Smart Home Monitoring System and Simply Safe. I was checking if there is anything else out there that you would recommend., or if you have had experience with either and would recommend or not recommend either of those two. Thanks in advance.
