hi. I purchased iDmss plus app on my Ipad. It worked fine in first two days of my usage but after that I can not access my cameras through the internet. it works fine on an android device but there is time out or login failed problem on ios. I live in Iran and my technical support for installation of cameras can access them over the internet but i cant. DVRs are dahua. i use an IP /Domain type of register mode please let me know what should i do to access the cameras again.... thanks shirana
