Should You VLAN in Your New Home's Network? 

Excellent Video! Personally, if you can install VLAN's, install them! VLAN's is a subject where you can ask 10 professionals the same question and you will likely get 10 different answers and or approaches. I have the UDM-Pro, USW Pro24 port switch, and a UNVR. I also have 9 VLANS. Why, because I like to know exactly where things are and what they are doing, without having to guess where they are. Default, Admin, Printers, Guest, IoT, Cameras, Media Center, VPN and Webpage. Once you install them and set them up they care for themselves. I am in the process of setting up the Firewall and traffic rules, which can be a little intimidating, especially when you want to give the Guest access to the printer, Internet and nothing else or some IoT access to the Internet and other IoT no access. Trial and error... There is so much you can do by putting everything in their own VLAN. With UI's enhanced log, that should help even more if you need to troubleshoot. Oh, if you have a UNVR get yourself a 50' Fiber cable and move the UNVR to a hidden location away from the equipment rack in case someone does gain access while you are gone and they will not have access to the Camera recording hard drives. I put a defective hard drive with the connector pins removed inside the UDM-Pro so if someone did break in and see the rack in the utility room they would pull the defective HD thinking it was holding the camera videos, while the camera in the ceiling by the light is recording them removing it, on the relocated UNVR.

The Cameras. You mentioned constantly getting notifications, I resolved that by creating a "Custom Schedule" in the "Push Notifications Settings". I turn notifications "ON" between the hours of 7:30 PM and 7:30 AM. During those hours I just have "Person" and "Vehicles" set for notifications. During the time between 7:30 AM and 7:30 PM there are no notifications. I do have 3 cameras that do not use the "Custom Settings" schedule (Global) and are set to send a notification anytime a person or vehicle is captured by the camera. Usually either Amazon or the Lawn Guy. I believe I only had 1 night time activation and that was at 3AM when a car pulled up on our driveway to turn around. Very happy with this setup.

I know you mentioned in one of your videos that pre-wire is so important, and it is so very important. I would also add to your list of things to pre-wire in a new construction is wiring in a JKT (quad-wire that used to be used for telephone land lines) to each window/door and back to your network area so that you can install an "Open/Closed" switch on each of them. I am totally an UN-WiFi and Cloud type of guy as that is just another method for hackers to get into your system. All my devices are Zigbee and not WiFi. For less than $100 a person can purchase a WiFi/Cell Phone signal jammer and can render your Security and WiFi devices useless, while they access your home/business. With the hard wired door/window sensors you can use Home Assistant (or another system) to monitor them and send a Text message to your phone, even if the RF signals are being jammed. It is interesting that alarm sensors will probably be going a full 360 where in the old days they were all hard wired and now to insure better security coverage we will be going back to that method. As a pre-wire it may not be utilized right away, but one day that home owner will be happy that he/she pre-wired in the sensor cables. Just a thought!

100% you should be setting up vlans and block rules on your HOME network ! the amount of chatter and snooping devices do these days EWW! OH and a Guestnetwork that is 100% isolated & protected too !

I wish that the UDMPro would be able to block every country in the world. With the exception of my home country. Granted not every country has hackers ( Like the Vatican) But it would make things a little better. Plus than you could block IP's with firewall rules.

@ethernetblueprint, my Sonos is on my IoT vlan. How do I set firewall rule such that my default vlan can communicate to my Sonos which is on my IoT vlan?

Addressing the elephant in the room. This guy is catering to someone with an unlimited budget. In the real world most users would be looking for a budget home network.
