Bit rate control
Constrained bit rate:
A complex scene generally produces a larger file size, meaning that higher bandwidth
will be needed for data transmission. The bandwidth utilization is congurable to match a
selected level, resulting in mutable video quality performance. The bit rates are selectable
at the following rates: 20Kbps, 30Kbps, 40Kbps, 50Kbps, 64Kbps, 128Kbps, 256Kbps,
512Kbps, 768Kbps, 1Mbps, 2Mbps, 3Mbps, 4Mbps, 6Mbps, 8Mbps, 10Mbps, 12Mbps,
14Mbps, ~ to 40Mbps. You can also select Customize and manually enter a value up to
40Mbps.
• - Target quality: Select a desired quality ranging from Medium to Excellent.
- Maximum bit rate: select a bit rate from the pull-down menu. The bit rate ranges from
20kbps to a maximum of 40Mbps. The bit rate then becomes the Average or Upper bound
bit rate number. The Network Camera will strive to deliver video streams around or within
the bit rate limitation you impose.
- Policy: If Frame Rate Priority is selected, the Network Camera will try to maintain the
frame rate per second performance, while the image quality will be compromised. If Image
quality priority is selected, the Network Camera may drop some video frames in order to
maintain image quality.
Smart Q: Select ON or OFF to enable or disable the feature. Smart Q is scene-aware. The
Smart Q reduces frame size and bit rate consumption through the following:
■
Dynamically adjusting the image quality for scenes in different luminosities in low light
frames. Less noises means less of the bandwidth consumed.
■
Endorsing different qualities for the I frames and P frames, and hence reduces the
frame size.
■ Dividing a single frame into different sections, and giving these sections different
qualities. For a highly complex area, such as an area with dense vegetation, screen
windows, or repeated patterns (complex textiles patterns like wall paper), having a
lower quality value actually poses little effects on human eyes.
Unnecessary quality is unrecognized by human eyes and wastes the bit rate.
The Smart Q streaming can save up to 50% to 80% of bandwidth in different illumination
conditions while keeping the same imaging quality. These numbers come from the
comparison between Smart Stream II and Smart Stream III streamings.
