itself.

Certificate Authority (CA). This requires that a list of trusted CAs are uploaded to the 
system in advance.

asked to present a certificate to the video system to identify itself.

Authority (CA). This requires that a list of trusted CAs are uploaded to the system in

corresponding certificate has been revoked, then the HTTPS connection will not be used.

status.
