5 Restrictions; Known Issues
• If UAC is set to default in Windows 7, no snapshot or recording via LIVEPAGE is possible.
• Only H.264 Main Profile using CABAC is supported. CAVLC is not supported.
• The camera date/time will be set to default (Year 2000) after power loss exceeding the buffer
period. It is important to ensure that the date/time is correct for recording. An incorrect
date/time setting could prevent from correct recording.
• After firmware upload while daylight saving time checkbox is activated the time zone must be
adjusted.
• After reboot, the system time re-synchronisation may be delayed up to 9 seconds for SNTP
respectively up to 14 seconds for time server protocol.
• LUN size for local recording via “Direct iSCSI” is limited to 2 TB.
• VRM version 2.12 or higher is required.
• In some cases formatting errors on external iSCSI drives may occur, which might need
multiple tries to overcome.
• In rare cases it may happen that the owner of an iSCSI LUN is not displayed correctly.
Recording is not affected, just previous owner remains displayed.
• If a device had primary and secondary recording running on SD card and is then added to a
VRM system, the blocks used for primary recording will not be re-used, reducing the available
recording space for the ANR recording. This can be solved by re-formatting the SD card.
• Throughput limit for simultaneous recording and local replay at 100% playback speed is:
o maximum total recording bit rate of 7 Mbps for external iSCSI recording
o maximum total recording bit rate of 10 Mbps for SD card recording, depending on
SD card performance
• SD card recording performance is highly dependent on the speed (class) and performance of
the SD card.
• FTP exported files which include audio in a format other than AAC must be renamed from
.mp4 to .m4a to allow correct playback in QuickTime.
• If the memory protection inside the Internet Explorer is enabled (default setting), the automatic
installation of Autoload Decoder will fail without producing an error message.
Consequently, the replay page will not show video.
As a work-around, two options are available:
o Disable memory protection in Internet Explorer and re-connect to the device.
o Manually download the Autoload Decoder installer from the device.
The installer can be downloaded via http://<ipaddress>/setup.exe and started manually.
• With I-frame-only recording and audio also enabled for recording, audio will be fragmented or
not audible during replay. Please disable audio recording in case of I-frame-only recording.
• With JPEG Posting active when device is booting, the first posted JPEG image may be a no-
cam logo.
