Stream settings

On the Stream Settings page, you can configure performance and bandwidth settings for C•CURE IQ.

In the performance settings, you can prioritize frame rate or resolution, depending on your bandwidth limitations. In the bandwidth settings, you can select a network type that reflects the capabilities of your network. Each network type defines a maximum bit-rate value to be received from video servers.

You can choose to preserve either frame rate or resolution by selecting the appropriate radio button. If you choose to Prefer Frame Rate, then the stream of the highest rate in the offered palette that most closely matches the desired resolution will be selected. If you choose to Prefer Resolution, then the stream that most closely matches the resolution displayed is selected and allow lower frame-rate streams are picked from the palette.

You can configure bandwidth settings to reflect the capabilities of your network. From the Stream Settings menu, you can select a bandwidth option from a list of network types. Each network type defines a maximum bit-rate value to be received from video servers. The client allocates a bandwidth limit to each individual active stream by intelligently distributing the total bandwidth limit associated with the chosen network type. The ability to change bandwidth type is based on the role allocated to the active user.

Note: The performance and bandwidth settings are global settings for C•CURE IQ.

Video bandwidth consumption is more efficient at lower stream resolutions. This is because there is a CPU penalty for every key frame decoded that also increases with resolution. This penalty is incurred regardless of FPS. With mega-pixel cameras at lower FPS it is recommended that Variable Bit Rate (VBR) is used or the CBR Bit Rate is proportionally reduced. Otherwise, the bit rate of each frame increases as the frame rate is reduced. No bandwidth savings can be achieved by reducing FPS unless this is done. This is also relevant for SD resolution cameras.

Variations in signal:noise ratio can affect bandwidth and CPU load. These variations might increase during nighttime conditions. Live frame rates might be reduced, and the CPU load can increase in such scenarios. Many cameras have functions that can compensate for these phenomena
