HikVision cameras, NVR, Acusense, different IP subnets(?)

Hi,
I would like to have 3 cameras to monitor outside of my home.
I’m thinking about Hikvision cameras with Acusense technology (to recognize ‘human’/‘car’ objects).

Looking at hikvision NVRs, it seems those cameras would be in different subnet, private to NVR, and access to them would be via NVR.
My questions:

  1. is it possible to have hikvision cameras in my main subnet, same as my HA, same as my laptop, same as NVR? Perhaps instead of nvr with built-in PoE switch, I should just buy seperete switch?
  2. if not, if the architecture of hikvision is that nvr needs to built it’s own private subnet, I suppose I could get a camera feed in my HA dashboard via NVR… but - wouldn’t I ‘loose’ acusense features in HA ?

I have a hikvision doorbell. It does have a camera on it. It’s poe device connected to poe switch. Switch and a doorbell/camera are on the same subnet as ha.
I dont have cameras around my house because it will be very complicated to run lan cables.
This doorbell can trigger snap shoots and record video on movement. Everything is saved in ha for defined period of time. Its integrated in ha with frigate addon and integration. It can recognize home/car/cat/dog objects.
As I said before downside of this camera is lack of coral resulting in high cpu usage from time to time. As I saw on net coral accelerator is pretty expensive.

Yes the nvr places the cameras on a different subnet. You can relay the feed from the nvr’s lan port though. Not sure about accusense.
