Setting the Record Rate
In Intellex IP, camera resolution is measured in Common Interchange Format (CIF).
The higher the camera resolution, the more system resources are consumed. A camera at 4 CIF
resolution uses 4 times the system resources as a camera at CIF resolution. If all cameras are
configured at CIF resolution, you can configure an aggregate rate of 480 ips. If all cameras are
configured at 4 CIF resolution, you can configure an aggregate rate of 120 ips. If all cameras are
not at the same resolution, determine the maximum aggregate rate:
1 Divide 480 ips by the number of connected cameras.
2 For each connected camera, divide the value from step 1 by:
• 1 if the camera is in 1 CIF mode
• 2 if the camera is in 2 CIF mode
• 4 if the camera is in 4 CIF mode
3 Example: If cameras 1–8 are in CIF mode and cameras 9-16 are in 4 CIF mode:
• 480/16 = 30
• For cameras 1–8: 30/1 = 30
• For cameras 9–16: 30/4 = 7.5
• Max. aggregate = (30 x 8) + (7.5 x 8) = 300 ips
CIF Record Rate
1 CIF = 320 × 240 pixels < 480 ips
2 CIF = 640 × 240 pixels < 240 ips
4 CIF = 640 × 480 pixels < 120 ips
