Notes:
• Click the [Measurement] button after setting the recording rate/transmission rate by clicking the [SET] button.
• Do not change the settings in the process of the measurement.
• In the process of the measurement, recording, playback and live image display will stop. Other users currently
accessing the unit will forcibly be logged out.
• They need to log in the unit after the measurement. The result value is the reference value.
• Depending on the network traffic, different result value may be displayed even when the [Measurement] button is
clicked without changing the settings. Depending on the network traffic or other causes, the following may occur.
• Live images are not transmitted as configured
• Images are not recorded as configured
• Response of the web browser becomes slow
• The web browser is disconnected
• Recording is not carried out
We make no guarantee for any damages incurred by recording malfunction or error occurrence regardless of
what the cause may be.
[Measurement] button
It is possible to check if the set recording rate and trans-
mission rate are available for the network in use by
clicking the [Measurement] button. It will take around 90
seconds to check. In the process of the measurement,
recording will stop. When the set rate is displayed red,
recording/transmission may be failed with the set rate.
Check if the result value (total value of the maximum
network speed of each camera) is below the maximum
network speed of the unit (30 Mbps as indication).
When the result value is beyond the maximum network
speed of the unit
(Example: 30 Mbps < 50 Mbps (result value))
When the result value is beyond the maximum network
speed of the unit (30 Mbps as indication), refer each
rate for "LIVE VIDEO", "MANUAL REC", "SCHEDULE
REC" and "EVENT REC". Then, lower the higher rate
among them or lower image quality to diminish the net-
work traffic from the camera. Click the [Measurement]
button to check if the result value is below the maximum
network speed. Repeat this procedure until the result
value becomes less than 30 Mbps (as indication).
Important:
• When the result value is beyond the maximum net-
work speed of the unit, the following may occur due
to the heavy network traffic:
• Some images to be recorded may not be done.
• Some live images to be displayed may not be
done.
• Some alarms to be issued may not be done.
• Operational response may become slow.
• Even when the result value is below the network
speed (30 Mbps as indication), the above problems
may occur depending on number of the connected
cameras and PCs. The following table shows the
reference values.
• Network traffic changes every moment. In any cir-
cumstances, the result value should be less than the
maximum network speed of the unit (30 Mbps).

*1: Each recording rate for "MANUAL REC", "SCHEDULE REC" and "EVENT REC"
*2: When images from 5 camera channels or more are simultaneously displayed on the currently accessing PCs,
transmission rate of "LIVE VIDEO" will be controlled in order to put a high priority on recording.
