To ensure a reliable performance of Siveillance Control even with large data volumes, observe the following instructions when you configure data.

Computer and Network Performance

If the performance of the system becomes slow, always check the performance of the network.

The system performance is automatically optimized in the background; you need not make any specific settings. Please take into account that the computer performance and main memory are dependent on the number of configured detectors, cameras and such. If 10,000 detectors are configured additionally or the total number of detectors in a room exceeds 50,000, the system response may become slow in certain situations. In such cases the main memory of the runtime or the engineering client should be expanded to 24 GB.

Data Supply

  • Never create more than 1,000 objects under a Location Tree node.
  • No node should have more than 7 subordinate levels (hierarchy levels).
  • If the CUPS printer service is active on the engineering and the runtime server and print jobs with many pages are started frequently, the overall system performance will be affected.
  • If you create your own bookmarks in the Message List view or the System Tree, the system may be slowed down by repeated database scans. Avoid creating bookmarks that are not necessary.
  • In small systems with up to 5,000 data points, you do not have to restrict the creation of bookmarks. In case of large systems with 50,000 or more data points, this issue should be discussed with the Siemens service technician or hotline.


Graphics can contain quite a lot of detector symbols. When opening a graphic with 4,000 or more detectors, there may be a delay of 2 to 3 seconds if all detector symbols need to be loaded.

  • The loading speed of a graphic depends on the number of individual objects that have been configured. Clean up your graphics using appropriate graphic editing programs before importing them and remove any details that are not relevant to the site plan.
  • In large graphics with many detectors, the detectors should be grouped.

Video Streams

Video streams have an effect on the network and the utilization of the client. If, for example, five or more different video streams are displayed simultaneously on the runtime client, a higher-performance graphics card should be used to reduce the processor load. Use the Windows Task Manager to check if the CPU load is increased considerably when a camera is connected. If possible, use a network connection with a data rate of 1,000 Mbit/s.

Delete Data

If a large number of objects need to be deleted on the engineering client, this should be done step by step, preferably 400 to 500 objects at a time, in order not to slow down the deletion process. Delays may also occur when deleting a large number of completed messages or events. Siveillance Control can process up to 50,000 completed messages under 5 minutes.
