In AutoDomes, blanked sector may trigger a “too dark” alarm.
On AutoDomes, privacy masking does not cover the complete configured area if privacy mask
is placed too close to the edge of a scene. Move the target position to the center of the scene
before creating a privacy mask.
If a local media is exchanged, existing former recordings are only discovered after rebooting
the device.
AAC audio timestamps for UDP live video streams as well as for recording streams are based
on 90 kHz instead of 16 kHz to ensure compatibility with VideoSDK.
AAC audio timestamps for TCP live video streams are based on the standard 16 kHz
timestamps. Standard players should connect to live video with AAC audio using TCP.
If LIVEPAGE is refreshed during recording of Tour A/B on AutoDomes the button “Stop
display” will falsely display “Start recording” but still continue tour recording.
There is only one configuration for IVA. When analysis type is changed, e.g. from IVA to IVA
Flow, the former configuration is lost. Due to this, it is not possible to change the analysis type
in a VCA profile switch.
If FTP export files contain only a few frames some players might not correctly replay such a
file, or the replay is too quick to recognize something. The exported file is not corrupt though it
might seem so.
After a firmware upload it may happen that the Privacy Masks and settings from Installer Menu
are set to default. Make sure to check if Privacy Masks and Installer Menu settings are still
valid after uploading new firmware.
Due to a limitation of the script language that is used in the background, the delay timer for
event-triggered VCA starts immediately when the configuration is set. A trigger event during
this period does not restart the timer. Once the timer has elapsed, operation is as desired.
On devices with VCA FPGA an outgoing IPv6 connection fails when device is initiator, e.g.
trying to resolve a time server domain name,
Files exported using continuous FTP backup for Rec. 2 where stream 2 is set to I-frames only
mode contain wrong timing information and play back too fast.
Some online help files describe a tracking icon which is not visible, documentation obsolete.
IP addresses 172.20.1.0/30 which include 172.20.1.0 to 172.20.1.3 are reserved for internal
communication and must not be used as device addresses. Products without internal
communication ignore this restriction and allow the use of this range.
For stream setting “Dual ROI” the maximum resolution of stream 2 is 288p regardless of a
higher resolution selected in the encoder profile.
After changing the selectable camera mode via alarm input the switch back to a previous
mode doesn't work anymore.
Firmware upload stops recording when it fails or is terminated.
FTP export file size is always 100 MB if resolution change occurred in exported time span.
After downgrade configuration integrity cannot be ensured and settings need to be checked or
re-configured.
Google Chrome requires a plug-in for displaying TIFF images to properly show the reference
image.
