I hope someone can explain me how to use an alarm from a hikvision camere (like line crossing or motion) and than trigger a preset on a other hikvision PTZ camera. I have a DS-2CD2332-I IR 2.8 in the garden looking into it from the house wall. There is a DS-2DE5220I-AE installed on the same wall high above. So if the DS-2CD2332-I has for example a line crossing alarm, i would like the PTZ to go to a preset straight down, so i can see from aboven what happens against the wall what is out of sight for that DS-2CD2332-I There is a DS-7616NI-E2/A NVR, so perhaps that can do it when it receives an alarm from cam1 to send a preset command to cam2. i searched for a solution, but i could only find triggers for NO or NC ports on the NVR to ring a bell, or turn on a alarm light or something. This is image from the side: It is not a 2032 in the garden any more, but i did not upgrade the diagram yet.
