The frame rate will decrease if you select a higher resolution.
■ Intra frame period
Determine how often to plant an I frame. The shorter the duration, the more likely you will get
better video quality, but at the cost of higher network bandwidth consumption. Select the intra
frame period from the following durations: 1/4 second, 1/2 second, 1 second, 2 seconds, 3
seconds, and 4 seconds.

Video quality
Constant bit rate:
• Constant bit rate: A complex scene generally produces a larger le 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, and 8Mbps. You can also select Customize and manually enter a value.
You should speciy the bit rate setting either as an Average restriction or as an Upper
bound threshold. If set to the Average, video bit rate will uctuate around the Target
bit rate setting.
• Fixed quality: On the other hand, if Fixed quality is selected, all frames are
transmitted with the same quality; bandwidth utilization is therefore unpredictable.
The video quality can be adjusted to the following settings: Medium, Standard, Good,
Detailed, and Excellent. You can also select Customize and manually enter a value.
►
Video quality and xed quality refers to the compression rate, so a lower value will produce higher
quality.
►
Converting high-quality video significantly increases the CPU load, and you may encounter
streaming disconnection or video loss while capturing a complicated scene. In the event of
occurance, we suggest you customize a lower video resolution or reduce the frame rate to obtain
smooth video.
