CA servers
In cryptography, a Certification Authority (CA) is an entity that 
provides signed digital 
certificates for use by other parties, and thus acts a trusted third party. 
There are many commercial CAs that charge for their 
services. Institutions and 
governments may have their own CA, and there are free CAs available.

NTP server every 60 minutes. Specify the NTP server's IP address or host name.
• Se
t manually - this option allows you to manually set the time and date.
Note: 
If using a host name for the NTP server, a DNS server must be configured under TCP/IP settings. See Net-
work > Advanced TCP/IP Settings below.

24h) displayed in the Live View video streams.
Use the predefined formats or use your own custom date and

your own date and time formats.
