Seems like Power over Ethernet would be a pretty good standard to go with. Right now it's good for 25.5 watts at 44 volts. Wikipedia says some vendors have tweaked the standard to use more lines and get it up to 51 watts. To over-simplify, the higher the voltage the less loss there is on the wire for a given amount of energy (amps).
Added bonus you get ethernet too so any devices like LED lights, cameras, etc can be programmable without wifi/zigbee/etc.
- ars 13y agoPower over Ethernet only helps for not having to run a second pair of wires. You would still need a DC/DC converter, and if you do that you might as well just go from AC. PoE is helpful certainly, but not as a way of having universal DC in the house.
- Amadou 13y agoYou would still need a DC/DC converter, and if you do that you might as well just go from AC. You are thinking wall-wart type applications. I'm more along the lines of infrastructure, lights and other permanently installed devices that can be designed from the ground-up to operate at 44v.
- ars 13y ago> designed from the ground-up to operate at 44v. Why? What's the benefit over 110v?
