However, you may want to specifically define the operation of a piece of equipment. For
example, you may have one Camera that is fixed, so you do not want to enable the “move”
functions for the operator when running AV Player. In this case you would specifically set up
and configure a named Camera. Any functions expressly defined for the named Camera will
override the global Camera information in the AV Switch configuration.
Similarly, the Camera configuration will define
global information about the Presets for the
Camera, including the number of the Presets that are to be generated in the namespace. For
example, if the Camera definition generates 20 Presets, then the 20 Presets will exist in the
namespace tagged with the namespace name. However, if you want to give a specific name
to the Presets, you would need to specifically set up and define each Preset in the CCTV/AV
Configuration window.
Namespace and Database
When you define the CCTV Server, AV Switch, and other items in the CCTV/AV
Configuration window (except for Dry Contacts), the software creates a database
table for each item, and will also create a valid entry for the AV Switch in the AV
Server namespace. If the system then uses the default settings for the DVR protocol,
as many entries are added to the namespace as there are default items, but no
database tables will be created for these items until one of the items has been
specifically created, configured, and saved. For example, if you specifically create a
Preset, a record will be created and it will contain information about the named
Preset. When you create the Preset, you will allocate the Preset a number that the
software will use to create the namespace name (OPC name) for the Preset. The
namespace entry will be updated from any information in the database when the
CCTV Server is next started.
Relationship Between the Namespace and Database
The following illustration summarizes how the various system activities relate to the
namespace and database.
