Hikvision NVR & Onvif ip cameras

Hi,

Does anyone know if when connecting an ONVIF camera to an Hikvision NVR via plug 'n' play, does it alter the password to the IP camera?

I manually set the IP camera password to a default expected by Hikvision NVR, and changed the ip address to be within the Hikvision NVR subnet.

After enabling virtual host, I cannot log into the ip camera with the password I had setup prior to connecting it to the hikvision NVR.
