Metadata Extensions Configuration
Extended metadata searching in the Surveillance Video Manager requires metadata that can be
collected at ingest only if MetadataExtensions.cfg is configured correctly for Camera policies.
In short, the metadata you ingest using Camera policies will be searchable using the
Surveillance Video Manager. Therefore, metadata extensions for Camera policies and the
Surveillance Video Manager are all covered here together.
The Metadata tab and metadata search options will appear in the Camera Policies
application and the Surveillance Video Manager respectively only if there is a
MetadataExtensions.cfg file in <install-dir>
\Config .
The MetadataExtensions.cfg file must be on every computer on which a user would edit
or modify the recording policy. If not, the metadata values could be lost.
When you create, configure, and implement a MetadataExtensions.cfg file, the Metadata tab
will appear in Camera Policies. It will contain the Query blocks listed in the IngestMdExt block
(see details below):
Metadata search options will be available in the Surveillance Video Manager to enable searches
using metadata associated with already captured videos.
When you ingest metadata, special characters normally interpreted as wildcards (?, *, #,
!, ~, ^, &, [ ], { }, \, ") are not interpreted as wildcards. When you search for metadata,
however, wildcards are recognized. Consequently, if metadata that you ingest contains
characters that are normally interpreted as wildcards, when you search for metadata you
need to use the escape character (\) to denote that the wildcard is intended literally, not
as a wildcard. For example, if you ingest 16*37 as metadata, and you then want to
search for this expression, you would search using 16\*13.
The search type options will be identical to those you defined in the ModMdExt block
(see details below).
