I successfully get a number from the Hikvision camera(model iDS-2CD7A26G0/P-IZHS), the answers from this topic helped me. But this solution works for cameras with firmware 5.5.130. I also have cameras with firmware v5.5.804 build 210831 for which there are no alternative builds. I get an invalid operation when I try to request a number.
Camera parameters:
Model iDS-2CD7A26G0/P-IZHS Serial number iDS-2CD7A26G0/P-IZHS20210129AAWRF40749141 firmvare V5.5.804 build 210831 code version: V7.3 build 210806 plagin version 3.0.7.30 firmvare kind C-R-H7-0
For the request I am using the following parameters in postman
