Thanks, yet again.
I remember a Hikvision camera firmware resolved, iirc, a backdoor type exploit on their cameras. You also needed a reasonably strong password after that update.
The downside on applying it was that password reset tools would potentially not work and you would need to contact Hikvision and go through the process required to unlock that camera again.
With having Chinese hacked cameras, altho five of them were "altered" to be ENG based, I haven't found much in the way of features added over the years.
The NVR with its VCA grid type search has been useful over the years, and the recorded material successfully used.
Hopefully something similar will be employed with the Reolink NVR's.
If not sure how successful and well implemented the ONVIF std is with those cameras to use with, for example, a Hikvision NVR and for all its features to be available.
As noted those Hikvision cameras I bought a while back from Ali were Chinese hacked but the price was palatable.
