10pcs DC Power Adapter 5.5x2.1mm Female Jack to 2.5x0.7mm Male Plug Electrical Socket Outlet for Laptop Interface Power Cable Connector

I have an e1 zoom wired up the way mblaser described. Specifically I used this splitter https://a.co/d/063ptLpt with this adaptor https://a.co/d/0epLvVCo. Connected over Ethernet/poe and has been running great for probably a year. Can confirm the crying detection works as well. I don't use it for it, but had a newborn that it would pickup. I ended up turning the crying detection off to stop all the extra events it generated
