this change and use the discover cameras CGI, the axis cameras may be added again. The
workaround would be to delete the Axis cameras and add again. Once the cameras with the
old ids are gone, the problem won‟t occur.
A PTZ preset can not be added to Q7406 encoder ( and other Axis encoders such as the
241Q and 243Q ) with American Dynamics Ultra 8 analog PTZ camera because the
Sensormatic PTZ driver does not support the query=position command.
An attempt to add a preset to Axis encoders ( with AD Ultra 8 analog PTZ camera) will result
in a “Error: query not implemented “ HTTP error being returned in response to a
“<ipaddress>/axis-cgi/com/ptz.cgi?query=position&camera=1” HTTP request. The reason for
this is that the Sensormatic driver for the AD Ultra 8 camera does not allow the position to be
queried. The parameter list retrieved from the encoder will report that absolute pan, tilt, zoom
is not supported
An attempt to add a PTZ preset for Axis Q1755 fails because the getPositionSync method
returns “Not supported” error as a result of the Axis Q1755 not returning pan and tilt position
info when PTZ position is queried. The zoom position is returned but not the pan and tilt
position. Since the Q1755 cannot pan and tilt without the motor accessory then perhaps the
need to set presets for zoom only is not critical.
Axis 212 can‟t pan/tilt if the camera is fully zoomed out. The area that can be pan or tilted
increases as the camera is zoomed in further.
When Axis 214 PTZ is zoomed out near to full out position, it will suddenly zoom in for some
amount of distance.
When Axis 212 PTZ is zoomed in or zoomed out, it stops near full position and can‟t reach to
full position.
When an Axis 240Q or 241Q four-port encoder is added to the NVR, camera slots will be
created for all four ports regardless of whether the encoder inputs are receiving analog
signals. If an analog signal is not preset, black video will be received by the NVR and
recorded/streamed to viewing clients. To conserve NVR disk space and reduce network
traffic, the camera slots associated with the unused inputs can be deleted from the NVR but
they cannot be added again unless the entire encoder is deleted and re-added.
The latest firmware ( 4.47) in the Axis 210A camera and some other VAPIX 2 camera and
encoder models have a flaw that limits the FPS of MJPEG streams to the FPS of an existing
MPEG-4 stream until the MPEG-4 stream is destroyed. For example, if the configured FPS of
two MJPEG streams are 20 FPS and 5 FPS and the FPS of the MPEG-4 stream is 15 FPS
then the actual FPS of the MJPEG streams will be 15 FPS and 5 FPS until the MPEG-4
stream is destroyed. Similarly, if the MPEG-4 stream is 1 FPS then the actual FPS of the two
MJPEG streams will be 1 FPS. A workaround is to ensure that the FPS of an existing MPEG-
4 stream is greater that the configured FPS of the MJPEG streams. Another workaround is to
revert the Axis firmware to an older version ( 4.40 for example ) which does not exhibit the
symptom.
After an Axis camera has been disconnected from the network, the handler can take up to 22
seconds to raise an alarm and attempt a reconnect after the dry contact connection to the
device is lost. However, the loss of the video stream from that camera will be detected within
a few seconds and an alarm will be raised.
If the camera‟s own web GUI is used to rotate an image ( instead of using the NVR web client
“Image Settings” screen ) then the change does not take effect on existing streams until an
FPS or resolution change causes the stream to be destroyed and recreated. It is better to use
the NVR web client “Image Settings” screen to rotate the image because that will cause the
stream to be destroyed and recreated.
When using /axis-cgi/com/ptz.cgi?camera=1&areazoom=<int>,<int>,<int less than 100> Axis
API to zoom out on Axis 214 PTZ camera, the zoom position will reverse to maximum zoom
in when the request causes a zoom out to go beyond the widest zoom out position. This,
