■ALARM Recording
The WJ-NT104 records images before and after an alarm is activated and notifies the user of alarm input. Alarm images
can be recorded in the following three modes:

●Single Frame Recording mode

When an alarm is received, the alarm image is captured and saved as a still image after the specified delay time.
• The delay time from receiving an alarm until capture of the alarm image can be specified in the range of 0 to 10 sec-
onds in increments of 100 ms.

●Continuous Recording [after alarm] mode

When an alarm is received, the specified number of alarm images are captured and saved after the specified delay time.
• The delay time from receiving an alarm until capture of the alarm image can be specified in the range of 0 to 10 sec-
onds in increments of 100 ms.
• The number of images to save can be set to between 1 and 16 (resolution 640 x 480).
• A frame rate of 1/10, 1/5, 3/10, 1/2, 1, 2, 3, 5, or 10 can be selected.
• If another alarm is received while recording an alarm, the on-going alarm processing is suspended and the new alarm
image is recorded with priority over the preceding one.

●Continuous Recording [before/after alarm] mode

Images before receiving an alarm are recorded at the preset frame rate and in the preset number of images. After an
alarm is activated, the specified number of images are continuously captured and saved.
• The total number of images to be saved before and after an alarm can be set to between 1 and 16 (resolution 640 x
480).
• A frame rate of 1/10, 1/5, 3/10, 1/2, 1, 2, 3, 5, or 10 can be selected. (Frame rate 10 is not available for recording
before an alarm event.)
• If another alarm is received while recording an alarm, the on-going alarm processing is suspended and the new alarm
image is recorded with priority over the preceding one.
Note: This mode is valid only in Fixed Input Selection
mode is selected.
