Considerations
■Clock data setting of a CPU module
Before operating a camera recorder module, set the clock data in a CPU module. If the clock data is changed after operating
the camera recorder module and the time does not match between the camera recorder module and a network camera, a
network camera communication error (error code: 1DF1H) occurs.
For details on the clock data setting, refer to the following:
MELSEC iQ-R CPU Module User's Manual (Application)
■Time synchronization using SNTP
When setting the time synchronization by using SNTP, the synchronization timing and interval depend on the specifications of
a network camera used.
■Time zone and daylight saving time
The time zone and daylight saving time are not set for a network camera from a camera recorder module.
■Time setting using a dedicated tool for a network camera
Do not use a dedicated tool for a network camera for the time setting.
If it is used, the time information does not match that of a camera recorder module.
■Synchronization with the time information of a device and label
It may take time to synchronize a time stamp of video data delivered from a network camera with the time information of a
device and label. Check the synchronization status in 'Time synchronization status' of a camera recorder module.

If the time synchronization is not completed, a video file is generated with a time when video data is received by a camera
recorder module, not a time when video data is captured by a network camera. This may cause an error due to network delay.
