This is the setting menu screen for alarm-activated recording.

Camera
Select an alarmed camera for the alarm.
Alarmed camera will be recorded when corresponding sensor is activated.
Note
Even if a camera is not set to record according to the schedule, it can be recorded by means of sensor-activated
recording.
Note
Each camera belongs to one and only one group and can share the total frame per second of the group up to
25/PAL (or 30/NTSC). In case of alarm recording, the recording speed of alarmed camera is automatically increased
to a possible maximum value. The value can be calculated as follows: If the number of alarmed cameras is
n
and
the signal system is PAL, then the recording speed of alarmed camera is

. For example, if
there is one alarmed camera, the channel will be recorded at the speed of 22 fps while other 3 channels will be
recorded at the speed of 1 fps. Likewise, if there are two alarmed cameras, those channels will be recorded at the
speed of 11 fps each while other two channels will be recorded at the speed of 1 fps.
The connecting channels of each group are as shown below.
Group 1=Channel number 1,5,9,13 / Group 2= Channel number 2,6,10,14
Group 3=Channel number 3,7,11,15 / Group 4= Channel number 4,8,12,16
Setting value will not be saved if the frame number setting exceeds 25 fps. The remaining frame number at the left
bottom of the screen is displayed as [-] if the frame number setting exceeds 25 fps. In this case, error message
appears, and frame number will not be saved even though [Save] button is pressed. Set the frame number so that
the total frame number does not exceed 25 fps.
To set frame number by each group, check the remaining frame number after setting the frame number for each
group, then press the [Save] button. The setting value will not be saved if there is wrong setting for any group.
