Video

The Video window allows you to congure all video streams (the no. of stream available can be

different for different models). You can congure the following:

1. Codec: video compression codec in H.264 or MJPEG. Note that MPEG-4 is not supported for

Liveview.

2. Frame size: video resolution. Note that due to the limited CPU resources, you may not be

able to change the resolution to a very high value, e.g., 5MP in the 1920x1920 resolution.

3. Maximum frame rate: the highest frame rate.

4. Intra frame period: How often an I-frame will be inserted into the video stream.

5. Video quality: You may either select Constant bit rate or Fixed Quality as the dening rules for

video transmission:

Constant bit rate Places a packet size threshold on video frames; This guarantees

the frame rate per second performance, yet image quality can be

compromized if bandwidth is not sufcient in your network environment.

Fixed Quality Guaranteed video quality, and to ensure image quality, some frames may

be dropped.

When done with the conguration, click the Apply button.
