AXIS P3304-V Fixed Dome Network Camera

Video and Au dio

To avoid bandwidth problems on the network, you can limit the frame rate allowed to each viewer. The maximum frame rate can be

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

An image or text can be superimposed over the image as overlay. See Overlay, on page 19.

Save your settings befo re they can take effect.

H.264

H.264, also known as MPEG-4 Part 10/AVC, is a video compression standard that provides high quality video streams at low bit rates.

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

whereas P-frames and B-frames only conta in the differences from previous/future frames.

The GOV length is the number of frames between two c onsecutive I-frames. Increasing the GOV length may save c onsiderably o n

bandwidth requirements in some cases, b ut ma y also have an adverse affect on image 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 increased activity in the image, and less for lower image activity. CBR allows you to set a

ﬁxed Target bit rate that consumes a predictable amount of bandwidth. As the bit rate would 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, select the Include text check box option under Overlay Settings

and enter the code #b in the ﬁeld.

MJPEG

Sometimes the image size is large due to low light or complex scenery. Adjusting the maximum frame size helps to control the

bandwidth and storage used by the Motion JPEG video stream in these situations. S etting the fram

esizetotheDefault setting

provides consistently good image quality at the expense of increased bandwidth and storage usage in low light. Limiting the frame

size optimizes bandwidth and storage usage, but may give poor image quality. To prevent increased bandwidth and storage usage,

the maximum frame size should be set to an optimal value.

Stream Proﬁles

There are four pre-programmed stream proﬁle s ava ilable 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 sel ect the default stream proﬁle go to Live View Conﬁg > Stream Proﬁle and choose the proﬁle from the drop-down list.

Camera Settings

The Video & Audio > Camera Settings page provides access to advanced image settings for the Axis product.

Image Appearance

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

black and white image.

The image Brightness can be adjusted in the range 0–100, where a higher value produces a brighter image.

Increasing the Sharpness can increase bandwidth usage . A sharper image might increase image noise especially in low light

conditions. A lower setting reduces image noise, but the whole image will appear less sharp.
