7 CAMERA RECORDER MODULE (DETAILED SPECIFICATIONS)
Description
The number of invalid camera events among those received is
stored.
When the operating status of the recording function is
'operating' and the camera event receiving status is 'waiting
for receiving,' the number of invalid camera events among
those received is stored.
(Value to be stored: 0 to 65535)
Details are the same as network camera 1.
The operating status for video data is stored. (Page 278
Camera recording status (Un\G1650 to 1657))
0: Stopped
1: Preparing
2: No setting
3: Operating
4: File saving trigger satisfied
5: Saving
Details are the same as network camera 1.
The maximum period (seconds) during which video data can
be accumulated is stored at the current bit rate.
It is calculated with the following formula each time video data
from a network camera is accumulated.
• Accumulation period = Recording buffer size  Average bit
rate
If a period exceeds 4294967295 seconds, 4294967295 is
stored.
Details are the same as network camera 1.
Whether received video data is accumulated in the recording
buffer is stored.
0: No data
1: Data exists
'1' (data exists) is stored when video data is received and
accumulated in the recording buffer.
'0' (no data) is stored when saving a recording file starts.
When a recording startup trigger is satisfied, accumulated
data is discarded and '0' (no data) is stored.
When the operating status switches to 'operating' after starting
the recording function, '0' (no data) is stored. (It is initialized to
'0' (no data).)
Details are the same as network camera 1.
Details are the same as recording status 1.
