5.1.
Introduction
Each Video Grabber can be configured using web-based GUI that is accessible via its IP (See 4, p. 13).
While this method of configuration gives user all the necessary options it does not give the user a way
to automate certain actions. This is what SNMP is for.
5.2.
Accessing the Video Grabber via SNMP
Information available via SNMP is organized into sections that group objects of the same kind (e.g.
there is a section called ‘information’ that groups objects like ‘productName’, ‘serialNumber’ etc). In
cases when there are a lot of objects subgroups are used (e.g. section ‘status’ has subsections
‘staGeneral’, ‘staVideo’, ‘staNtp’ and ‘staRtsp’).
Each object can be accessed using any SNMPv3 capable tool using its Identifier (OID) which at the same
time defines its place within the hierarchy. The OID has a form of string of numbers that has the
following structure:
VIDEO GRABBER.SECTION.SUBSECTION.OBJECTNUMBER.0
Video Grabber supports SNMPv3 which means that user has to be authorized and the communication
is encrypted. By default there are two classes of users defined:
1)
Read-only user – this user can get information from the Video Grabber (e.g. CPU
temperature, uptime, configuration settings etc.), but cannot change the configuration. This
user is suggested for use with any kind of Monitoring systems.
2)
Read-write user - this user can not only get information from the Video Grabber, but also
can change its running parameters (e.g. set the output format, change compression settings
etc.).
While most actions do not require MIB files, there are some that do. For that reason 3 MIB files have
been created:
-
Video-Grabber
-
Video-Grabber-Status
-
Video-Grabber-Config
