Problems with AXIS Media
Control (
Internet Explorer
only
)
To enable the updating of video images in Internet Explorer, set the browser to allow ActiveX
controls. Also, make sure that AXIS Media Control is installed on your computer.
No H.264 displayed in the
client
Check that the relevant H.264 connection methods and correct interface are enabled in the AMC
Control Panel (streaming tab). See
AXIS Media Control (AMC) on page 11
.
In the AMC Control Panel, select the H.264 tab and click
Set to default H.264 decoder
.
Check that RTSP is enabled under
System Options > Network > TCP/IP > Advanced
.
Multicast H.264 only
accessible by local clients
Check if your router supports multicasting, or if the router settings between the client and the
product need to be configured. The TTL (Time To Live) value may need to be increased.
No multicast H.264
displayed in the client
Check with your network administrator that the multicast addresses used by the Axis product
are valid for your network.
Check with your network administrator to see if there is a firewall preventing viewing.
Installation of additional
ActiveX component
restricted or prohibited
Configure the Axis product to use a Java applet for updating video images in your browser. Go to
Setup > Live View Config
and select Java applet under
Default viewer
.
Poor rendering of H.264
images
Ensure that your graphics card is using the latest driver. The latest drivers can usually be
downloaded from the manufacturer’s website.
Lower frame rate than
expected
See
Performance Considerations on page 57
.
Reduce the number of applications running on the client computer.
Limit the number of simultaneous viewers.
Check with the network administrator that there is enough bandwidth available.
Check in the AMC Control Panel (H.264 tag) that video processing is NOT set to
Decode only
key frames
.
Lower the image resolution.
The maximum frames per second is dependent on the utility frequency (60/50 Hz) of the Axis
product. See
Technical Specifications on page 53
.
Video and image problems, general
Image unsatisfactory
Check the video stream and camera settings under
Setup > Video > Video Stream
and
Setup >
Video > Camera Settings
.
Motion Detection triggers unexpectedly
Changes in thermal radiation
Motion detection is based on changes in thermal radiation in the image. This means that if there
are sudden changes in the ambient temperature, motion detection may trigger mistakenly. Lower
the sensitivity setting to avoid problems with thermal radiation.
Storage and disk management problems
Storage disruption
A storage disruption alarm is sent if a storage device is unavailable, removed, full, locked or if other
read or write problems occur. To identify the source of the problem, check the
System Log
under
System Options > Support > Logs & Reports
. Depending on the problem, it might be necessary to
re-mount the storage device.
For information on how to set up a storage disruption alarm, see
Events on page 31
