For your CCTV lookup Frigate NVR, and grab a ~30 Coral TPU for it. Run your cameras with a PoE switch.

Home Assistant is THE gold standard for smart homes. ZigBee is nice too, since they mesh and aren’t the same wave length as WiFi.

Unfortunately Zigbee is precisely 2.4GHz, which isn’t used much for phones and laptops, but still widely used in TVs, vacuum robots and other smart devices that don’t need much bandwidth.

  2.4Ghz is the right frequency to use - it has pretty good wall penetration. And since you don’t need much bandwidth to turn alight on, there’s nothing wrong with a bit of competition on the channel.
  
  Your TV/etc shouldn’t be on a wireless connection.

    2.4GHz ia good in theory, in practice tho, every technology especially the open protocols use it so there is a lot of interference. I know that because I had to lower the 2.4GHz wifi power by a lot so it doesn’t cause issues with the zigbee mesh.
    
    As for tv I would agree if TVs came with gigabit NIC, but the majority comes with 100mbps card, so if you want to stream some high quality 100+mbps content you have no other option but to use the wifi or give up the usb port for a usb ethernet nic or use a usb hub. Not pretty solitions for sure.
    
    And then you have the robot vacuum which can only use 2.4GHz wifi for obvious reasons. And people might have IPcams which are also on wifi.

    Zwave is nice, but a lot more expensive due to hardware certification costs

For my money, KNX>Zwave>Zigbee. Zigbee’s standard are not certified so you get non compliant devices that don’t work well, and 2.4 is a very crowded frequency with lots of interference not only from other wireless devices but also microwaves, etc. Zwave solves both of these issues and generally has a higher level of quality, but for me a wired standard will always beat a wireless one if I’m starting from scratch.
