status area
Network camera 2 status area
Network camera 3 status area
Network camera 4 status area
*1 A unit that indicates the maximum number of frames delivered from a network camera per second.
*2 Supported for ONVIF supported network cameras only.
*3 The maximum bit rate depends on the performance of a network camera used; therefore, a setting value and an actual bit rate may
differ.
For details, refer to the manual for a network camera used.
*4 The setting is applied when '1: supported' is stored in 'Video rotation angle support' (Un\G34237).
*5 For details, refer to the following:

*6 For details, refer to the following:
Page 286 Error log area (Un\G34311 to 34472)
*7 An average value calculated based on eight moving averages is stored.
It is not stored in the buffer memory before eight values are sampled.

Description
The total number of times an error log is registered in the
error log area is stored.
An error log number in which the latest error log is
registered is stored.
0: No error
1 to 16: Error log number
The code of an error occurred for a network camera is
stored.
b0 to 7: Time zone and summer time flag
b8 to 15: System area
b0 to 7: Last two digits of the year
b8 to 15: Month (01 to 12)
b0 to 7: Day (01 to 31)
b8 to 15: Hour (00 to 23)
b0 to 7: Minute (00 to 59)
b8 to 15: Second (00 to 59)
b0 to 7: Day of the week (0: Sun, 1: Mon, 2: Tue, 3: Wed,

b8 to 15: First two digits of the year
b0 to 7: First two digits of the millisecond
b8 to 15: Last two digits of the millisecond
Details are the same as error log 1.
An average bit rate value (kbps) in communication with a
network camera is stored.
The total number of frames lost while receiving video data
for the past 60 seconds is stored.
If incomplete data due to packet loss, etc. is included in a
frame that configures video data received from a network
camera, it is deleted for each frame and the cumulative
number of deletions is stored.
The status of time synchronization between a camera
recorder module and a network camera is stored.
0: Time not synchronized
1: Time synchronized
Time is synchronized when the time stamp of video data
delivered from a network camera and the time information
of a device and label are synchronized. It may take time to
complete.
The video data receiving status of a camera recorder
module is stored.
0: Not receiving
1: Receiving
Details are the same as network camera 1 status area.
