Thank you for your answers!
The smart analysis has never worked for the two cameras. I only succeeded with an older Hikvision camera (DS-2CD2432F-I) and only when the ONVIF protocole is activated (not the one from Hikvision)
I've seen the video and I don't think I missed a step. The problem is...
For the moment I have the following configuration:
- DS-2CD2045FWD-I (firmware: V5.6.3build 190923)
- DS-2CD2145FWD-I (firmware: V5.6.2build 190701)
And one NVR:
- DS-7608NXI-I2/4S (firmware: V4.1.18build 200120), so with AcuSense.
All the settings are made on the NVR web...
