Does anyone know if the ONVIF video stream between the camera and the NVR is encrypted by default?  If not, how do i enable encrypted transmission?  Also, the feed between the NVR and the PC (VIGI security manager) or the mobile device (VIGI app) encrypted?  if not, please describe how to enable encryption.  Thank you!

note: i am using HIKVISION DS-2CD2543 & DS-2CD2523 cameras via ONVIF
