I run a Control4 system with distributed audio and video. All devices are IP-based/controlled, such as the TVs. Here is a breakdown of the system.
Overview
This is a 22u rack, with everything centrally controlled. All cables have their own home-run to make things a lot cleaner on the other end.
Network
I chose to use a Ubiquiti Unifi Network for switching, routing, and wireless. It gives me plenty of control to monitor and configure my. network to my needs. I have separate VLANs for different device types; one for the main/wireless LAN, one for IoT (wired/wireless), and one for my homelab services.
Distributed Audio
The receiver for the main floor lies in the rack as well. The main appliance is a 4 zone Triad matrix. It feeds into a 4 zone amplifier from Sonance.
Distributed Video
Distributed video is always my favorite. All TVs have a fiber optic HDMI run, which gives the most bandwidth when running at higher resolutions & color spaces. Most cables are rated for 4k@120/8k@60 to future proof things. Everything is fed into a Monoprice 8×8 HDMI matrix. It can handle HDMI 2.0, so I can take advantage of 4k@60 with Dolby Vision/Atmos.
Control System
I chose to go with a Control4 system because of its reliability and ease-of-use. It adapts to any configuration of equipment pretty easily. It handles all zones of audio and video, and has powerful automations.
Lighting
I run a combination of WiFi bulbs (WLED) and Shelly dimmers. Both the bulbs and Shelly run a locally controllable API, so no worry for slow response times or none at all in the event of an outage. The Shellys are tied to regular light switches, so they can still operate standalone. I also have some grouped together to trigger lighting scenes.
