I am building a house and trying to avoid power bricks and cables hanging on the wall for motion sensors, blind shutters, “add next smart house blinky here”.
This is just an aexample photo:
So I was thinking each IOT needs to have internet connection anyway. What about if I run a single CAT cable to each room, and position a switch in each room to split to couple CATs in each room (power socket, tv socket, window, ceiling fan). Main CAT from each room to go to the server room router. That way I can have one cable per room coming out from the router. And with some inexpensive POE switches in each room I can split to extra IOTs.
That way I wont be saturating the home wireless and needing expensive APs. And in the same time can deliver POE. Alternatively I can modify the CATs to run only 4 wires for 100MB network and remaining 4 for 12V if POE injection is complicated or routers cant deliver required IOT current.
I must say most IOTs will be DIY ESP/Arduino/MCUs
Is it possible you guys think?
For more budget friendly recommendations, the unifi switches are great but expensive while used Aruba 2920 POE’s are $130 on eBay. Unifi UAP pro can handle 50 devices on 1 AP, most houses can be covered by 2 maybe 3.
Axis cameras are big money bad value and good for commercial use if you’re going Exaqvision over Blueiris, Dahua are great value and can do color night vision now for much less. There are some solid Amcrest offerings around too. Avoid wireless cameras over wired.
I wouldn’t recommend buying wifi devices without matter support at this point. Thread solves congestion issues. Zigbee might be 915 or 2.4ghz but your demanding devices will run on the 5ghz anyways.
Good point on the home theater! You can run all your speaker wires now. Don’t forget power for smart door locks!
