Hi, I have installed a hikvision DS-KD8003-IME1 video door entry system consisting of a main external unit and 4 external units of four houses with 2 monitors per house. I have configured everything and everything works perfectly. the only problem that I have not been able to solve is how to show only the main external unit is the private one without being able to see those of the other villas. can you help me? thank you
