Enable auto stream size: The Auto Stream Size feature dynamically adjusts the stream sizes of video feeds from network cameras in order to reduce CPU load and bandwidth consumption.

It is often the case that in surveillance deployments the physical dimensions of monitors, the effectiveness of visual stimulus, and the operators' regions of interest can all be very limited. Streaming large-size videos at all times will be a waste of bandwidth and system computing power. CIF and VGA size videos are usually sufficient for the operators of a surveillance software.

When enabled, your LiveClient station automatically requests smaller-size streams as video feeds (any from streams #1 ~ #4) from the network cameras. For example, the frame size of video stream #4 will be reduced to 320x240 (CIF). Depending on the actual size of view cells on the LiveClient monitoring screen, the server automatically requests different video streams.

When the size of view cells is manually expanded, a server requests a different stream. This is called Stream Jump. Shown below are the details of the corresponding stream jumps.

View cell size

Stream jump to...

4:3 resolutions

<= 320x240

stream #4 (CIF)

> 320x240 or 640x480

stream #1

16:9 resolutions

<= 384x216

stream #4 (CIF)

> 384x216 or 640x360

stream #1

1:1 (fisheye cameras)

<= 384x384

stream #4 (CIF)

> 384x384 or 640x640

stream #1

Facts about Auto Stream Size:

The LiveClient utility automatically adjusts stream selection according to the size of view cells, no user's configuration is required.

The frame size of stream #1 is user-configurable. The server only resizes stream #4.

If a user disables the Auto Stream Size function later, the frame size of stream #4 will not be restored to the previous configuration.

Stream jump takes place on the display of all connected cameras once the function is enabled.

The Auto Stream Size function does not apply to the Matrix view.

If users configured a region of interest before the Auto Stream Size function is applied, e.g., via the ePTZ control, the view cell might display a different live view.

Enable de-interlace function: Select this option if your connected device does not support de-interlace

function. For example: VS7100.

Enable Instant Replay on video cell: Here you can change the duration of a playback that happened immediately before a user utilizes the instant playback function.
