Evidence locks

You can add, edit, and delete evidence locks, but you can also export them and play back video with evidence locks.

Evidence locks (explained)

With the evidence lock functionality, you can protect video sequences from being deleted, for example while an investigation or trial is ongoing. This protection also covers audio and other data from devices related to the selected cameras.

Once an evidence lock is in place, the system prevents the data from being deleted automatically based on the retention time of the system.

Depending on the user rights defined by your system administrator, you may or may not be able to create, view, edit and delete evidence locks.

Description and result

Scenarios and solution
Succeeded

All went well.

Result:

The evidence lock is created/updated/deleted.
Only partially successful

If the creation, update or deletion of an evidence lock was not entirely successful, an only partially successful message is shown and the progress bar is yellow. Click Details to see what went wrong.

Result:

The evidence lock is created/updated/deleted but without including some of the selected cameras and/or their related devices.

Additionally, this can be because a recording server is offline, in which case the evidence lock is configured, but not yet applied on the actual video. In this case, the evidence lock will be applied to the video when the recording server becomes available. You can verify that the locks are applied by looking at the size of the lock. An indication of size means that the lock is applied.

Scenario: Some of the recording servers with devices included in the evidence lock are offline.

Solution: Wait for the recording server to come online.

Scenario: One or more devices have recordings on recording servers that are not upgraded to 2020 R2 or later.

Solution: Upgrade the recording servers to version 2020 R2 or later.

Scenario: Your system administrator has changed your evidence lock user rights after you logged into XProtect Smart Client.

Solution: Contact your system administrator.
