3 Restrictions; Known Issues
• 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.
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 2.10 or higher is required.
• In some cases formatting errors on external iSCSI drives may occur, which might need
• VRM version 2.10 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 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.
• With streaming set to 1080p or 720p50/60, AES encryption is not possible.

• For HD cameras the encoder property setting “H.264 BP+ (bitrate limited)” can only be
selected for the downscaled second stream.
• For standard definition devices the encoder property setting “H.264 BP+ (HW Decoder)” can
only be selected for one stream. If the second H.264 stream is configured for this property, the
selection of the other stream will be changed to “H.264 MP Low Latency”.
selection of the other stream will be changed to “H.264 MP Low Latency”.
• Encoding bit rate for Baseline Profile plus (BP+) is limited to maximum 1.2 Mbps, regardless
of any other setting in the encoder profile, without the special Global License Key applied.
Additional delay will also be applied; maximum end-to-end delay might be up to 400 ms.
