Image

You can modify the image resolution and compression, and rotate the image fro m the Image tab (Video & Audio > Video Stream).

The image can also be mirrored from the Image tab.

Setting the compression level affects the image quality and bandwidth; the lower the compression, the higher the image quality

with higher bandwidth requirements.

To avoid bandwidth problems on the netw ork, you can limit the frame rate allowed to each viewe r. The maximum frame rate can be

set to Unlimited, or you can limit the frame rate to a v alue.

An image or text can be superimposed over the image as overlay. See

Overlay, on page 19

Save your settings before they can take effect.

H.264

H.264, also known as MPEG-4 Part 10/AVC, is a video compression s tandard that provides high q uality video streams at low bit r ates.

An H .264 video stream consists of different types of frames such as I-frames , P-frames and B -frames. An I-frame is a complete image

whereas P-frames and B-frames only contain the differences from p re vious/future frames.

The GOV length is the number of frames between two consecutive I-frames. Increasing the GOV length may save considerably on

bandwidth requirements in some cases, but may also have an adverse a ffect on imag e quality.

ThebitratecanbesetasVariable Bit Rate (VBR) or Constant Bit Rate (CBR). VBR adjusts the bit rate according to the image

complexity, using up more bandwidth for incre ased a ctivity in the image, and less for lower image activity. CBR allow s you to s et a

ﬁxed Target bit rate that consumes a predictable amount of band width. As the bit rate wou

ld usually need to increase for increased

image activity, but in this case cannot, frame rate and image quality are affected negatively. To partly compensate for this, it is

possible to prioritize either frame rate or image quality. Not setting a priority means that frame rate and image quality are equally

affected. You must save your settings before they can take effect.

The current bit rate can be set to appear as text overlay. To do this, selec

ttheInclude text check box option under Overlay

Settings and enter the modiﬁer#b in the ﬁeld.

Stream Proﬁles

There are four pre-programmed stream proﬁles available for quick set up. The settings for these can be adjusted. New customized

proﬁles can also be created. Each proﬁle has a descriptive name, indicating its purpose.

•Thestreamproﬁles can be accessed from the Stream proﬁle drop-down list in the Live View page.

• To add, copy, modify, and remove stream proﬁles go to Video & Audio > Stream Proﬁles.

• To select the default stream proﬁle go to Live View Conﬁg > Stream Proﬁle and choose the proﬁle from the drop-down list.

Image Appearance

Increasing the Color level increases the color saturation. The value 100 gives maximum color saturation. The value 0 gives a

black and white image.
