hello. friend.
firstly, please check if your set the mobile surveillance port correctly
secondly, there is an option in the DVR software interface about enable/disable mobile view access, make sure the option is set as enable
thirdly, try another android phone see if it works, because as far as I know, some cheap android mobile phone do not support online video view in flash format, please check if your cellphone can view online youtube videos
by the way, we are manufacturer and exporter of Stand Alone DVRs and cameras from China, we are looking for distributors in Brazil market, I attached our catalogs and price list for your reference
