im going thru this issue now also... Zosi sent me a firmware update... didn't help. Zosi smart was app on smartphone and AVSS was app on PC.. set ports correctly on router and all... phone app seems to work decent.. never could get pc app to work.. and the zosi cameras switch back to 720P at night with drives my old dvr crazy.. so they are useless to me... i am wanting to return it also. I also was looking for another app to view online and gave up..365 secu, xmeye.. nope...
