■If the communication with a network camera is disconnected
Video data cannot be received or accumulated.
Receiving and accumulating video data restart when a retry is successful.
If there is a period during which the communication is disconnected in a saving period, only video data in the period during
which the communication is established can be saved.
The following shows the flow of receiving and accumulating video data if the communication with a network camera is
disconnected.

 The communication is disconnected, and data reception and accumulation stop.
 A retry is successful, and the data reception and accumulation restart.
 The communication is disconnected, and the data reception and accumulation stop.
 The communication is disconnected; therefore, the data accumulation does not start even after the saving is completed
(there is no video data, because accumulated video data is deleted when a recording file is saved).
 A retry is successful, and the data reception and accumulation restart.
• If the communication is disconnected, a communication retry start (event code: 00600) occurs.
• When a retry is successful, a communication retry recovery (event code: 00610) occurs.
• If the communication is disconnected for 10 seconds, a network camera communication error (error code:
1DF1H) occurs.
• Some network cameras stop delivering video data if disconnected for a long time.
In this case, video data accumulated before the disconnection is discarded and video data accumulated
after reception and accumulation restart is saved as a video file.
