VCA features - camera vs NVR

Hi,
As I understand it, the NVR doesn't do analysis; what happens is the camera (if it has the feature) detects, say, a 'line crossing event', and then raises an alert to the NVR. If the NVR supports this, then you can search through and analyse this from the NVR software.

Presumably if it is an older model NVR then you'd just get an 'alarm', so you'd still be able to search through, but just not with the same degree of granularity?
 
With IP cameras, you can configure either the camera or the NVR to detect.

With a newer NVR properly configured you can perform smart searches for events.

If you have new cameras but an older NVR you could configure the cameras to notify you e.g. App/email, you would then know where to look in the NVR recording.
 
Hmm, are you saying that a new NVR can do a line crossing in a camera that doesn't support it? Or does line crossing need to be supported by the camera for it to work at all?
 
Hi,
I`m looking for hikvision nvr that has internal VCA without being supported by the camera. Can you recommend anything?

Thanks!
