Surveillance deployments and Data Center Expert server performance

[EcoStruxureIT]

The number of cameras licensed for surveillance, and the surveillance settings for those cameras, can affect server performance.

The Camera Resolution and Target Image Capture Rate (frames per second) you specify in the Surveillance Activation Settings section of the "Surveillance Settings" display determine the amount of data generated. To support a large volume of surveillance data, the maximum recommended number of cameras licensed for surveillance, and their surveillance activation settings, are the following:

• Basic server: A maximum of 15 cameras at 10 frames per second (150 fps total for all cameras) and a resolution of 640x480.
• Standard server: A maximum of 125 cameras at 2 frames per second (250 fps total for all cameras) and a resolution of 640x480.
• Enterprise server: A maximum of 250 cameras at 2 frames per second (500 fps total for all cameras) and a resolution of 640x480.

With the maximum recommended number of cameras licensed, Data Center Expert server performance can be affected when:

• SNMP or Modbus devices are also monitored by the Data Center Expert server.
• The Data Center Expert server connects to the camera using SSL, specified in the Server Settings section of the "Surveillance Settings" display.
• System activity, such as performing a server backup or purge, or exporting a large report, is occurring.
