Setting Evidence Rules
An evidence rule is a function to determine access
permissions, retention period, and storage locations
of les (called Effect) by predened conditions (called
Criteria) when the les are registered in the database.
Click on [Rules]. The Rules screen is displayed.
Criteria
The meta-information of the le is used as Criteria.
Classify, Ofcer 1, Ofcer 2, Field1, Field2, Field3,
Field4, Field5 (Vehicle ID), and Bookmark Note are
specied as Criteria.
Effect
Access permission, retention period, and the storage
locations are specied as Effects. Access permission
determines whether or not the group may access the
le and its rights. The storage locations are selected
from among the locations displayed on the screen.
The retention period is determined by the evidence
rules, separated les and case les. The longest period
of the three conditions listed below will be the retention
period.
(1) When one le is applied to multiple rules but with
different retention period set, the longest retention
period will be applied to the le.
(2) When a le is a part of the separated les, the
longest period among the separated les will be
applied. .
(3) The longest period among the les associated with
the case le is applied. (This function is enabled
or disabled in System setup of the Back-End
Administrator application.)
Access permission is determined by the evidence
rules, user rights and group rights. If the rights have not
been set with the evidence rules, the rights set with the
User setting or Group setting are enabled. The Rights
that are set to be denied in the Rule Effects section are
disabled even if a user setting or group setting species
enabling the rights.
Default rule
If no rule is applied to the les, the default rule will be
applied. The default rule is created when the Back-End
Server is installed. The Effects of the default rule are as
shown below.
Access permission:
No right
Retention period: 90 days
Storage location: First storage location registered
on the Conguration Settings screen
The Default rule cannot be deleted. Only Store Days
and Storage Location in Rule Effects can be edited.
