When the Recording Server service is running, it is very important that Windows Explorer or other
programs do not access Media Database files or folders associated with your system setup. If they do,
it is likely that the recording server cannot rename or move relevant media files. This might bring the
recording server to a halt. To restart a stopped recording server, stop the Recording Server service,
close the program accessing the relevant media file(s) or folder(s), and restart the Recording Server
service.
Recording server data encryption (explained)
Siveillance Video systems support secure communication from the recording server to all clients and
services that retrieve data streams from the recording server including Siveillance Video Client.
The communication is encrypted using SSL/TLS, a protocol used for secure connections to a server
via the internet. The SSL/TLS protocol uses a pair of keys—one private, one public—to authenticate,
secure, and manage secure connections.
This encryption technology uses digital certificates from a certificate authority (CA) that you install on
the Windows operating system.
Requirements for the certificate:
• Issued by the CA for server authentication purposes
• Issued to the recording server so that the recording server's host name is included in the name
of the certificate, either as subject (owner) or in the list of DNS names that the certificate is
issued to
• Trusted on all computers running services that retrieve data streams from the recording server,
preferably by trusting the CA certificate that issued the recording server certificate
• The service account that runs the recording server must have access to the private key of the
certificate on the recording server. Key length and other properties are controlled by Windows
settings
You can enable or disable encryption during or after installation.
Encryption can be enabled and disabled per recording server. When you enable encryption on a
recording server, you cannot choose a mixture of encrypted and non-encrypted communication.
Encryption applies to all clients and services that retrieve data streams from the recording server:
• Siveillance Video Client
• Management Client
