DC 5V 2.4A Active PoE Splitter Power Over Ethernet 802.3af 5.5x2.1mm

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

They only have crying detection on indoor cameras (can't see why they would put it on an outdoor camera) and the indoor cameras aren't POE. You could sort of convert the E1 indoor cameras into a POE camera by using something like one of these: https://www.amazon.com/DSLRKIT-Splitter-Ethernet-802-3af-5-5x2-1mm/dp/B07ZH5V89T Takes a POE power source and at the camera splits it into ethernet and 5v power. Note that that one is just an example, you'd have to find one with the right sized 5v plug. By the way, here is the list of models that do support crying detection, it's not just the E1 Pro: https://support.reolink.com/articles/900000580243-Do-Reolink-Cameras-Support-Audio-Detection/
