About trusted CAs
Certificate validation may be required
when using TLS (Transport Layer
Security).
The video system may be set up to
require that a server or client presents
its certificate to the video system before
communication can be set up.
The certificates are text files that verify
the authenticity of a server or client. The
certificates must be signed by a trusted
CA.
In order to verify the signature of the
certificates, a list of trusted CAs must
reside on the video system.
The list must include all CAs needed in
order to verify certificates for both audit
logging and other connections.
If authentication fails, the connection will
not be established.
