I am using HIKVISION IP camera (DS-2CD204WFWD-I) & (DS-2CD214WFWD-I) with NVR for image processing (face recognition) using OpenCV and python.
currently, in-camera setting, I have selected 20fps whereas when I run my code I am getting frames at very slow speed like 1 frame after 5 seconds. so do I need to keep connected it with NVR or I have to directly use It's IP address for image processing? For face recognition, I am using Microsoft cognitive services (Face API).
