DW Spectrum User Manual
Lookup lists expand the functionality of Event Rules by enabling a range of values and wildcards to be applied to decision making logic. This can reduce the effort required to maintain rules and enable fewer rules to cover a greater range of conditions by managing one list instead of multiple rules.
Key Concepts:
•Lookup Lists can only be created and modified by Administrators and Power Users from within the Desktop Client.
•The contents of a Lookup List are continuously applied to all instances where the Lookup List is referenced.
•The wildcards of (?) for an individual character and (*) for all remaining characters are supported in Lookup Lists.
•Lookup Lists can be exported as a .CSV file and imported from .CSV, .TXT, or .TSV file types.
•New installations include empty, generic lists types named Allowed and Blocked that cannot be restored if deleted.
Example User Cases:
•Open a gate when a detected license plate is on an Allowed list.
•Trigger an alert when a detected license plate is on a Blocked list.
•Execute an action when an object described (size, color, shape) by an Object list is detected.
Types of Lookup Lists:
oCan be used in Analytics Events, Analytics Object Detected Events, Generic Events, and Plugin Diagnostic Events.
oAre created without association to any specific plugin, device, or rule.
oOnly contain one data field (column) and function similar to a list of keywords.
oAre tested against any entry on any word in the caption, the source, the description, and on any attribute value for an object.
oCan only be created in reference to a supported Object Detection plugin.
oAre used when there is a need to check for multiple attributes of a detected object.
oCan only be used in Analytics Object Detected Events and only for the same object type.
oA compatible camera and object must first be selected before the object list will appear as an option.
oAre checked for each attribute value from the list entry to the corresponding attribute values from the object, and they all must match.
oPermit users to select the attributes to include, all others will be ignored when testing for a match.
oWill treat all empty values as "Any" when testing for a match.
oRequire at least one attribute value to be defined and not empty nor set to any.
Lookup List Attributes:
•List name – a user defined label for the list.
•List type – select from the following list types:
•Column – user defined field ("license plate") that will contain values to be examined.
•Value – contains values for a defined column, for example the license plate values to be examined.
Import Export Considerations:
The topic pages for Generic Lists and Object Lists contain list import and export instructions.
