UDP multicast: This protocol allows multicast-enabled routers to forward network packets to all clients requesting streaming media� This helps to reduce the network transmission load of the Network Camera while serving multiple clients at the same time� Note that to utilize this feature, the Network Camera must be configured to enable multicast streaming at the same time� For more information, please refer to RTSP Streaming on page 69�

TCP: This protocol guarantees the complete delivery of streaming data and thus provides better video quality� The downside of this protocol is that its real-time effect is not as good as that of the UDP protocol�

HTTP: This protocol allows the same quality as TCP protocol without needing to open specic ports for streaming under some network environments� Users inside a firewall can utilize this protocol to allow streaming data through�

several 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 and for recognizing moving objects in the eld of view.

If the power line frequency is set to 50Hz, the frame rates are selectable at 1fps, 2fps, 3fps, 5fps,

The rmware will try its best to contain the size of video packets within the limitation

of a constant bit rate� This methodoloy enables easier calculation of the network bandwidth and storage space required for live viewing or video recording�

Policy:

- Frame rate priority - Firmware will try to maintain the target frame rate per second, while the image quality will more or less be compromised�

- Image quality priority - Firmware will try to maintain the quality of the video while the frame rate (no� of frames per second) may decrease�

The bandwidth utilization is configurable 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�

• Fixed quality: On the other hand, if Fixed quality is selected, all frames are transmitted with the same quality; bandwidth utilization is therefore unpredictable�

When so congured, the frame-rate-per-second performance can be compromised

in the event of insufficient bandwidth or network clogs� The video quality can be

adjusted to the following settings: Medium, Standard, Good, Detailed, and Excellent.

You can also select Customize and enter a number to designate image quality� The larger the number, the higher the compression rate, and hence image quality is lower� A small customized quality number means a low compression rate, and a high quality image�

- Maximum bit rate - While you want to ensure a reasonable image quality, you can still impose an upper threshold on the bandwidth taken for the video transmission�

The congurable bit rate ranges from 1mbps to 40mbps.

VIVOTEK

If JPEG mode is selected, the Network Camera sends consecutive JPEG images to the client,

producing a moving effect similar to a lmstrip. Every single JPEG image transmitted guarantees

the same image quality, which in turn comes at the expense of variable bandwidth usage� Because the media contents are a combination of JPEG images, no audio data is transmitted to the client�

There are three parameters provided in MJPEG mode to control 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�

If the power line frequency is set to 50Hz, the frame rates are selectable at 1fps, 2fps, 3fps, 5fps, 8fps, 10fps, 15fps, 20fps, and 25fps� If the power line frequency is set to 60Hz, the frame rates are selectable at 1fps, 2fps, 3fps, 5fps, 8fps, 10fps, 15fps, 20fps, 25fps, and 30fps� You can also select Customize and manually enter a value� The frame rate will decrease if you select a higher resolution�

■ Video quality 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�

• Constant bit rate: A complex scene generally produces a larger le size, meaning that

higher bandwidth will be needed for data transmission� To regulate the bandwidth consumption and storage space for recording videos, you can select the Constant bit

rate methodology. The rmware will try its best to contain the size of video packets

within the limitation of a constant bit rate� This methodoloy enables easier calculation of the network bandwidth and storage space required for live viewing or video recording�
