Ubiquiti Network

Hi I require a network design and then configuration of my existing home ubiquiti network. The design needs to be based on best practice and extremely secure. The home is a smart home with many IOT devices controlling most of the house. The features below are some of the items i can think of but ultimately you are required to use your expert knowledge to finalise the design. Implementation can be completed via webex screen sharing. Features - General home wireless network - IOT wireless Network for all the iot device that use 2ghz - Guest Network and portal page created - Kids Wireless network connected to OpenDNS VIP ( web filtering service i currently use.) Please suggest a better option. - Segregation of networks to provide optimal security - VPN so i have remote access into the home network from iphones, tablets etc - I would like all devices that need a static ip be assigned via mac address - Automated monitoring and intruder detection Devices in the network Ubiquiti UAG pro 4gateway (2 WAN connections) Ubiquiti AC Pro Wireless Access point Ubiquiti 24 port POE switch Synology RS819 4 bay rack mounted NAS (current acts as security NVR and backed up to Amazon Glacier) Happy to use for other functionality if better suited.
