Camera Scene Investigation – Sandbox_2025

Scene Check

Scene check allows you to compare live image alarms against a reference image and take appropriate action, if required.

Initial Setup

You will need:

Synergy 24.1.100 or higher
a Scene Validation license

to run the REST API installer (see your system administrator for access to this installer)

to run the Scene Check installer

You will need a device group containing the cameras to be used for validation. To set up a device group, go to Setup -> System Setup -> Advanced Configuration -> Users -> Setup Device Groups.

You will need to define a schedule for how often camera checking should take place. To create a schedule, go to Setup -> System Setup -> Advanced Configuration -> Setup Scene Validation Schedules

You will need a fault type specifically for scene checking. This categorizes the scene change and you can create whatever categories you require. To create these, go to Setup -> System Setup -> Advanced Configuration -> Video -> Setup Fault Types. Select the checkbox Scene Check to make this available for use in the scene check. This will display in the scene check as the 'scene change type'.

Running the Installer

Click Scene Check Setup.exe.

Click Next.

Select whether you are installing on a client or server.

Make sure that all applications are closed before continuing.

Click Next to run the Client Configurator.

Click Finish to close the client configurator.

Click Next to proceed with the server configurator.

Click Next to configure the scene validation service.

Click Next to configure the Synectics Alarm Service.

Click Next to create the scene check alarm.

Click Finish to close the configurator.

Configuring Scene Check

Go to Operation -> Scene Check.

Configuration Settings

First you will need to connect to the server used for hosting the ability to check and compare camera feeds.

Enter the IP address of the server and the username and password for accessing.

Select the device group containing the applicable cameras.

Camera Configuration

Once you have configured the device group, go to the Camera Configuration page.

Search or select a camera from the left-hand side. The camera details will display on the right-hand side. Make any applicable camera settings. These settings are set by default by the scene check installer but can be adjusted here.

Default values

Matching threshold = 0.5
Focus value threshold = 0.5
Light level threshold = 120

Select the schedule you have previously defined for the frequency at which cameras are checked.

Scene Check Alarms

Once configured, a list of the alarms from the available cameras is shown on the Scene Check Alarms page. The status of each alarm is also shown. The currently selected alarm will show as Active. Alarms that have been assigned to an operator but still require action will show with the status Review. Alarms that have not yet been looked at will have the status Unaccepted.

Click any camera alarm on the left-hand side with status Review to display and compare any changes to the reference alarm, which is shown on the right.

You can use the buttons on the right to change the layout and see when the last valid check was carried out.

For each alarm, you will be asked to validate whether the alarm is a valid one or can be ignored.

In this example, the operator has stated that the alarm coming in is a valid one. They should assign a scene change type to the alarm. They can also now determine what the follow up actions should be, for example, if a fault should be logged, if a new reference image is needed and so on. Once complete, click Resolve to mark as completed.

In this example, the operator has logged a fault. Once you have processed the alarm, it will no longer appear in the list.

In this example, you can see an alarm that can be ignored and is therefore marked as invalid.
