I have hikvision 32ch DS 7732NI, I am planning to install at least 25 IP Camera, where 15 IP Camera already installed in internal POE port with IP 192.168.254.x , and the rest connected via switch ethernet, the problem is i cannot custom adding the 17th IPCamera's IP (192.168.254.151) with custom adding options, but if i edit the existing port in port 15th it succeeded. i just wonder where is my mistake why i cannot adding via custom adding options.
