Image
The default image settings can be configured under Video> Video Stream. Select the Im age tab.
The following settings are available:
• Resolution. Select the default resolution.
• Compression. The com p re ss ion level affe cts the image quality, bandwidth and file size of saved images; the lower the
compression, the higher the image quality with higher bandwidth requirements and larger file size s.
• Rotate image. If required, the image can be rotated.
• Mirror. If required, the image can be mirrored.
• Maximum frame rate. To avoid bandwidth problems, the frame rate allowed to each viewer can be limited .
• Overlay settings.See
Overlay, on page 16

H.264
H.264, also known as MPEG-4 Part 10/AVC, is a video compression standard that provides high quality v ideo streams at low bit rates.
An H.264 video stream consists of different types of frames such as I-frames and P-frames. An I-frame is a complete image whereas
P-frames only contain the differences from previous 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 affect on ima
ge 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. CB R allow s 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 qua
lity are af fecte d negatively. To partly compensate for this, it is
possible to prioritize either fra m e rate or im age quality. Not setting a priority me ans that fram e r ate and image quality are equally
affected. You must save your se ttin g s before they ca n take effec t.
The current bit rate can be set to a ppear as text overlay. To do this, select the Include text check box option under Overlay
Settings and enter the m odifi er #b in t
he field.
MJPEG
Sometimes the image size is large due to low light or complex scenery. Adjusting the ma ximum frame size helps to control the
bandwidth and storage used by the Motion JPEG video stream i n these situations. Setting the frame size to the Default setting
provides consiste
ntly good image quality at the expense of increased bandwidth and s torage usage in low light. Limiting the frame
size optimizes bandwidth and storage usage, but may give poor image quality. To prevent i ncreased bandwidth and storage usage,
the ma ximum fram e size should be set to an optimal value.
Stream Profiles
Astreamprofile is a s et of pre-configured stream settings including resolution, compression, frame rate and overlay settings.
Stream profiles c a n be used:
• When setting up recording using action rules, see
Events, on page 26
.
• When setting up a continuous recording, see
Continuous Recording, on page 29
.
• In the Live View page — select the stream profile from the Stream profile drop-down list.
