ONVIF
33-5
Limitations
The ONVIF standard can be interpreted in slightly different ways by the various manufacturers
who provide ONVIF enabled IP Cameras. The NVR ONVIF handler has been written to
accommodate these differences but it’s been necessary to devise a number of configuration
guidelines to aid with supporting an ONVIF enabled camera.
Camera Feature Pre-Configure Camera Settings
IP Address User must pre-configure an IP address
Username NVR attempts communication using a suitable
native handler, followed by ONVIF handler
User must pre-configure the "admin" user
account and add their new password to the
NVR password group before adding the
camera to the NVR.
Multiplexed Video/Audio User should ensure the audio (if supported) is
available as main stream which is the default
setting Stream Type setting.
Dual Streaming For Dual streaming the user should pre-
configure the camera to determine the
codecs/frame rates and resolutions the primary
and secondary streams are capable of
providing.
Some cameras may require a unit reboot to
take effect of new settings
Dry Contacts Normally these must be enabled (if supported)
via the camera's web page and may entail a
unit reboot
Auto Iris/Focus If a camera supports the Iris and/or Focus
features then these settings can be either set
to auto or manually adjusted within Victor GUI.
However, disabling the auto feature is only
supported in the NVR web GUI. Therefore, if
the user is manually adjusting these settings
then the auto Iris and/or Focus settings in the
NVR GUI image settings page must be
disabled.
Known Camera Limitations
Bosch (Audodome Easy II) H264 fails to stream - known gstreamer issue
(http://comments.gmane.org/gmane.comp.vide
o.gstreamer.devel/41937)
Bosch send H264 video using a Payload Type
Number = 35 but gstreamer H264 depayloader
only accepts payload type number video in the
dynamic range (96-127)(Streams MJPEG OK )
Recommendation - Use the Bosch native
handler
HikVision Some settings need pre-configured and a
camera reboot to take effect
(Codec change, Dry contact alerts)
HikVision Motion Detection (where supported) should
NOT be enabled directly on the camera.
Motion Detection can be enabled via the web
NVR GUI for the camera
