Can not configure the "send mail" despite very, very, very many attempts (and combinations), the test result invariably resulting in failure ....! Note that I also have 3 other cameras "dome" that work perfectly for some time and were relatively easy to configure) .I tried in desperation to seek some technical support by email, but .. ... no answer!
