The overall performance of this part of security system is very good including a nice design. However, it is designed to function as the communication router for multiple battery reserved devices. I would strongly suggest to power backup this device because all communications with security devices are going down in case of power outage in the house. I would suggest to redesign it using embedded battery or at least to change the software on cameras and doorbells to reconnect to the router which is generally power reserved. The power outage event message should be send to the phone of the owner. Also, the cameras/doorbells should register and save at least the movement events in case the WiFi or the Internet communication is down. It does not require a lot of memory on board.
