[Measurement] button
It is possible to check if the set recording rate and
transmission rate are appropriate for the network in use
by clicking the [Measurement] button. When the record-
ing rate or the transmission rate is displayed in red, it
may be impossible to transmit live images or record
images at the current rate. It will take around 90 sec-
onds to check.
When the result value is beyond the maximum network
speed of the recorder, 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.
The recorder may reboot.
Even when the result value is below the network speed
(128 Mbps as indication), the above problems may
occur depending on number of the connected cameras
and PCs.
