Constant network connections from ONVIF Integration

Hi,
I have a few cameras connected to HA using the Onvif integration. Looking at my network usage, I can see constant connections established by HA to these cameras and constant data upload to HA. This is when I don’t event have HA open in any browser.

Anyone know if I can limit these connections to only when I open a camera stream in HA?

I have a few other POE cameras connected using generic camera integration and they do not appear to behave the same way.

Thanks.
