This Network Camera offers real-time H.264, MPEG-4 and MJEPG compression standards (Triple

Codec) for real-time viewing.

If H.264 / MPEG-4 mode is selected, the video is streamed via RTSP protocol. There are four parameters

for you to adjust the video performance:

■ Frame size

You can set up different video resolution for different viewing devices. For example, set a smaller

frame size and lower bit rate for remote viewing on mobile phones and a larger video size and a higher

bit rate for live viewing on web browsers. Note that a larger frame size takes up more bandwidth.

■ Maximum frame rate

This limits the maximum refresh frame rate per second. Set the frame rate higher for smoother video

quality.

■ 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

A complex scene generally produces a larger le size, meaning that higher bandwidth will be needed

for data transmission. Therefore, if Constant bit rate is selected, the bandwidth utilization is xed at

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, 12Mbps, 14Mbps, and 16Mbps. You can also select

Customize and manually enter a value.

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.
