Limitations

All 1 For cameras that claim to support absolute and auto

focus but fail to provide minFocus and maxFocus (the

focus range), the NVR web page (Image Settings ->

Lens/Sensor) will display the Auto-Focus option but will

not display the focus range when Auto-Focus is disabled.

The AXIS 215 is an example of such a camera.

2 Older versions of the AXIS handler may have set the

“exposure”, “input gain”, “WDR” and other parameters on

some AXIS cameras to invalid values.

3 The camera’s web interface can be used to determine

whether the camera parameters have been set to invalid

values. Click “Setup->System Options->Advanced-

>Plain Config” and then select the appropriate parameter

group (image source, PTZ, etc). The invalid values will

be displayed but will be appended with “(not

supported?)”. The AXIS handler will also see the “(not

supported?)” in the parameter value strings it reads from

the camera. If any invalid values are found then use the

camera’s web interface to change invalid settings to valid

settings.

4 After an AXIS camera has been disconnected from the

network, it 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.

5 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

recommended to use the NVR web client “Image

Settings” screen to rotate the image because that will

cause the stream to be destroyed and recreated.

6 If the customer needs to change the active state of a dry

contact input then it should be changed before adding a

corresponding alarm sensor otherwise an alarm/alert

may be caused as a result of changing the active state.

7 H264 VBR bitrate settings are not supported or available

on the NVR. If the VBR bitrate settings have been

changed via the camera web interface, the settings will

not impact the NVR configured streams.

8 The AXIS API does not provide the same functionally

across different cameras. When lens WDR property set

to “1”, the AXIS camera’s wide dynamic range settings

will be set to “on” for some cameras and for others to

WDR”3”. Setting to “0” will turn all to “off”.
