There are two versions of the Reolink, one is power over ethernet, called POE, which requires either a network switch capable of supplying power over a network cable. Or what is called a poe injector can also be used instead.Does the reolink need to be wired in?
The other is wifi and can either use the supplied power lead or a doorbells original wiring.
I prefer a powered doorbell over the ones using batteries as there is no messing around swapping and charging batteries.
