Hi all, newbie here to start asking questions - is there something to read up first so I don't re-ask basic things? Doing renovation/extension for sub-sale soon and want to plan out possibility of smart home (initially just on/off control for lighting and cooling). My basic reading so far is to use zigbee rather than wifi (zwave costlier), and it seems there's a few brands mentioned in recent pages (aqara? sonoff?) to investigate. The last time I looked into these things Tuya was the go-to, has that changed?

Should I prioritize wall + ethernet for CCTV or just POE?

As I understand, POE requires either injector or the switch to support POE. But my (possibly outdated) understanding is also that POE has a slightly higher risk of non-standard components causing devices to fry/burn (because of the increased voltage supplied). If my entire network no POE then theoretically less risk for all the wired devices (but then would need power point for every camera).

Thanks this is helpful. I'm familiar with CCTV which support wifi, as I currently using cheap china device for that (unfortunately the data is cloud-based and calling home to China too, would prefer to move away from that). So for me is option 1 or option 2, I guess as long as aesthetics not an issue option 1 is the most flexible (plus can always be converted to POE later on if the wall socket is needed for something else). Though I think external camera exposed to some splashing from rain maybe POE is safer?

Well obviously using CCTV with wifi different from using lan-connected. And more work required to have a local device which records the video/processes the feed. So you recommend to avoid tuya/ewelink for CCTV?
