I have only IPC-HFW3549T1-AS-PV-0280B with mircoSD card
The main problem for me is that General recording and Event recording casues playback problem. For example car detection. When I download recording from one hour then on this recording I can see some things two times. Car from general recording and car from Event recording. The effect is that I see two times one car or on person passing by on playback. This is problem If i Want to download longer recording. I don't know if this is bug or not. For this reason I disabled motion detecion. Did you faced similar issue?
I didn't have such a problem, and one of the cameras I own is from the same WizSenze series model
IPC-HFW3849T1-AS-PV, and everything works perfectly.
But I say again, everything is recorded on my NVR and I don't have an SD card inserted in the camera to try.
I assume that your problem is in the settings, so try to play with the settings in the camera, because motion detection has nothing to do with the medium on which the recordings are saved (is it the SD card or the HDD in the NVR), but the motion detection recording command exclusively gives the camera.
Do you also have these settings?
Through which application do you watch recorded material from the SD card, SmartPSS, DSS or something else?
