Troubleshooting For Recording - Canon VK-16 v2.0 Administrator's Manual

Troubleshooting for Recording

When a recording trouble occurs when playing back recorded vide data (e.g., data is not
found), you can guess the cause by checking the Event Logs of the VK-64/VK-16 and
Storage Server Log (re_log) .
Log
Event Storage Server
Connection to ERROR (connect) : socket type=
<Camera Server's IP (IMAGE/EVENT/COMMAND),
address> error: Error cameraserver= (<host>:<port>)
occurred (<Error No.>: win32_error= (<Winsock Error
<Description>) Code>:<Error Message>)
Ex. Connection to

Camera <camera> Effective recording
Effective recording
rate (y%->z%)
rate (<Recording rate

before change>
If the following message is also
<Recording rate after
recorded, a large amount of captured
change> %)
data may have been discarded:
Ex. Effective recording
➝
· Camera <camera>: <x>/<y> frames
rate (100 90.0%)
discarded due to busy frame queue in
last 1 minutes.
Camera <camera>: <x>/<y> frames
N/A
discarded due to busy drive thread in
last 1 minutes.
Camera <camera>: <x>/<y> frames
N/A
discarded due to busy frame queue in
last 1 minutes.
Error writing frame for camera <camera>:
N/A
<error message>
If the following messages are also
recorded, a large amount of captured
data may have been discarded:
· Camera <camera>: <x>/<y> frames
discarded due to busy frame queue in
last 1 minutes.
· Camera <camera>: <x>/<y> frames
discarded due to busy drive thread in
last 1 minutes.
No Storage Server Log
Recording to E:\drive is on
standby due to shortage
of free HDD space.
Cause
Error No. Description
10050 Network may be out
of service.
A Camera Server's
10054
network problem or
10060
session
disconnection due to
10061
Camera Server's
10064
reboot has occurred.
The effective recording rate is too low
(below 50 %).
· Sensor and motion detection events
occur too frequently, exceeding the
standard given by the guideline.
· CPU load of the Storage Server PC
may be high.
Load due to writing recorded video
data onto HDD may be too high.
CPU load of the Storage Server PC
may be too high.
· The specified drive may be unable to
be written.
· The time setting of the VK-64/VK-16
Storage Server PC may have been
changed to the past (in the NTP
operation environment).
Load due to writing recorded video
data onto HDD may be too high.
Countermeasure
Check the network (HUB, cables,
etc.) for any problem and confirm
that the Camera Server is
operating normally.
· Adjust the recording schedule and
sensitivity of motion detection.
· Check the CPU usage and
terminate any applications which
are putting heavy loads to the CPU.
Use the Windows' Performance
Monitor to check the writing status of
HDD. Review the recording
schedule or add servers as required.
· Use the Task Manager to find out
the application causing the problem.
· If the VK-64/VK-16 module
(AE.EXE) is causing the problem,
the event generation frequency
may be too high. Try the following:
- Shorten the Maximum retained
history setting for the recorded data
- Reduce the number of events to
generate
- Add servers to distribute the load.
· Check the drive for recording
video data.
· If you are using NTP to adjust time,
shorten the synchronization interval
➝
with NTP (e.g., 7 days 1 day).
Shorten the Maximum retained
history or add HDD. Also, review
the recording schedule.
