Spotlight Cam Wired - battery backup

Hi there,

I plan to buy a Spotlight Cam. Probably the wired would be a good option - solar is the alternative for me - I just want to see if it is possible to use battery backup with the wired one, or is it still “only wired” and goes down with a power outage?
(I’ve found an almost 1 year old related question, but maybe there were some developments… Battery backup option would be nice to bridge power outages.)
