How to provide redundant connection to cameras

Planning for redundant connection reservation to cameras

Planning recommendations:

• Select redundancy method.

• Plan the computing power of the servers according to the following guidelines:

  • Use CCTV system calculator.

  • When calculating, please note that the analytics modules enabled for the camera do not run on the backup server.

  • If a server that is the primary server for other cameras will be used to redundantly back up some cameras, this must be accounted for in the server's capacity planning.

• Determine the composition of license keys based on the required capabilities of the video surveillance system, the calculated computing power, and the following conditions:

  • The redundant server for a camera should be combined in a multiserver system with the primary server for that camera.

  • If the server is not the main server for any camera, but is a backup server for other cameras, it must have a license for at least one IP camera installed.

Setting up redundant connection to cameras

Warning

The instruction should be performed on the installed video surveillance system with active licenses.

The servers and cameras must also be configured.

There are two ways to configure a redundant connection:

On the Servers page

Follow the steps below to set up camera connection redundancy:

1. Launch the Eocortex Configurator application.

2. Go to the Servers page.

3. Select General settings from the list.

4. Go to the Cameras tab.

5. Assign redundant servers to the cameras.

6. Apply settings.

On the Cameras page

Follow the steps below to set up camera connection redundancy:

1. Launch the Eocortex Configurator application.

2. Go to the Cameras page.

3. Select the camera in the list and go to the Connection tab.

4. In the Backup server drop-down list, select the server that will serve as the redundant for the selected camera.

5. Apply settings.

Setting up a redundant server

For each redundant server, follow these steps:

1. Select a server in the list.

2. Scroll down the Information tab to the Backup (redundancy) section.

3. Turn on the Sending email notifications option if you want to send an email notification when redundancy is enabled.

   Warning

   When the Sending email notifications option is turned on, you need to configure the email sending settings. The settings window opens at Setup.

   

4. Set the redundancy mode to be used for all cameras redundantly reserved on this server:

   • When the Constant redundancy option is activated, the permanent-reservation mode will be used.

     Warning

     Cameras that use permanent backup will normally have two connections: from the main server and from the backup server. Thus, depending on the design of the cameras, the bandwidth may increase and/or the frame rate may decrease.

     Warning

     When permanent backup is enabled, email notifications about the backup will be disabled.

   • When the Fast redundancy option is activated, the fast-reservation mode will be used.

     Warning

     In systems where there may be intermittent, even short-term, disconnections between servers, enabling fast redundancy may result in false alarms.

Warning

The Fast redundancy option must be configured on the primary server.

If either of these options is not enabled, the normal redundancy mode will be used.

5. When all settings are complete, apply them.
