Hello, no, the camera does not support this.
You must use the mains adapter supplied.
See: https://www.tapo.com/de... - Question 5.11

Hello, as vbzschud wrote. Unfortunately not.
But, I've had it connected to a PoE extractor (12V) for a long time and no problems.
But, of course, it is outside the specs. -> means, no guarantee if it should smoke out.
However, there is a PoE extractor from TP-Link "https://www.digitec.ch/de/s1/product/tp-link-net-poe-splittertl-poe10r-poe-splitter-netzwerk-zubehoer-5803684", which has 9V.
