Focus Camera – To define the camera that will respond to this Alarm
Action. The default settings are Camera 1 for Alarm Action 1,
Camera 2 for Alarm Action 2, and so on.
Pre-record – Pre-record time to define how long (in seconds) before
the Alarm Action is triggered the Focus Camera shall be intensively
recorded (Note 2). Use the Up/Down arrow buttons to adjust the
value (0-10 seconds).
Post-record - Post-record time to define how long after the Alarm
Action is triggered the Focus Camera shall be recorded at Alarm
Recording Rate. Please refer to Camera Setup for Alarm Recording
Rate of Camera. Use the Up/Down arrow buttons to adjust the
value (5 seconds-60minutes).
Enable – Check to enable the Alarm Output when the Alarm Action
is triggered.
Alarm Out – To define which Alarm Output will be triggered when
the Alarm Action is triggered. NC and NO signals are available,
please refer to Alarm Out Setup. Click on the Down arrow button
to select one of the Alarm Outputs (AO 1-8).
Output – Alarm Out output state when the Alarm Action is triggered.
For NC signal, it’s always open, for NO signal close. The Normal
State above shows whether the selected Alarm Out is NC signal or
NO signal.
Buzzer On – To activate the internal buzzer or not when the Alarm
Action is triggered.
Note 1: When the Alarm Input that triggered the Alarm Action returns to normal,
the internal buzzer and the corresponding Alarm Output will return to
normal immediately.
Note 2: The processing power for the system is 25/50 FPS for PAL and 30/60 FPS
for NTSC(1xFPS/2xFPS model). So, if the total configured recording rate
for all the cameras is 5 FPS, intensive recording means that the actual FPS
for the Pre-record time for the Focus Camera is 5/10 times (for PAL) or 6/12
times (for NTSC) the configured normal recording rate for the Focus
Camera. The formula is:
Fp = Fn x 25(50) / Ft for PAL, Fp = Fn x 30(60) / Ft for NTSC
Fp: Pre-record FPS, Fn: normal FPS for Camera n, Ft: Total configured FPS.
