I have a Unify/Ubiquity solution. So if Onvif does not work it's no use. I will send the product back to the store. Too bad, the buildquality was really good and I really liked the solar solution....

@maf2a Hi, the option you are refering to in the 'advanced settings' where the account can be made is not there. At least not in my version of the TPLINK Android app. I have a C425.
