Video data reception and accumulation
Video data delivered from a network camera can be received and accumulated.
Based on information set in the following section, video data is delivered from a network camera.
Page 237 Video data delivery setting
For details on video data reception and accumulation, refer to the following:
Page 16 Recording Function
When using multiple recording settings in one module, a frame of video data being received may be lost if the
video data is saved and received at the same time. To reduce the number of lost frames, refer to the following:
Page 101 Operation setting at video data saving
Time synchronization control
The time can be synchronized between a camera recorder module and a network camera.
For details, refer to the following:
Page 240 Camera time synchronization function
PTZ control
PTZ control can be performed on a network camera if it is supported by the network camera.
For details, refer to the following:
Page 245 Camera adjustment function (PTZ)
Alive check
Whether the communication is established with a network camera can be monitored periodically.
If the communication is interrupted, retries are performed every one second.
If 10 seconds elapse for a retry, a network camera communication error (error code: 1DF1H) occurs.
The retry continues even if an error occurs, and video data reception from a network camera restarts when the retry is
successful.
In addition, a communication retry start (event code: 00600) and communication retry recovery (event code: 00610) are
registered in the event history.
The connection status can be checked for each network camera in 'Network camera connection status'
(Un\G34300, Un\G34800, Un\G35300, Un\G35800) of a camera recorder module. (Page 282 Network
camera status area (Un\G34000 to 37999))
Precautions
• When replacing a network camera with one with the same IP address, the communication restarts if the new network
camera can operate with the same network camera setting.
• Some network cameras stop delivering video data if disconnected for a long time. In this case, it may take a long time to
recover by a communication retry.
