ADVANCED OPERATION
ALARM
Video Blind is a feature that detects when the camera is covered or is being obstructed by light with the inability to capture live camera viewing. There are 6 sensitivity settings from Lowest to Highest. You are given the option of being informed of this event through Email or with the alarm status screen displayed. Click OFF or On to enable.
Alarm ManagementDELAY setting is the amount of time that recording will continue after the alarm is cleared.
ALARM OUTPUT sets the amount of time the output relay contact will stay activated after the alarm is cleared.
Alarm Inputs:Alarm inputs are devices or switches that activate when a door, window, cabinet etc. is opened or accessed. For example, you might want to only have the camera record when someone opens a tool cabinet or when a door opens vs. recording when motion occurs around those areas. There may be people moving by those areas frequently but you are only concerned about when those areas are accessed. This saves hard drive space and makes it easier to find an event that was recorded to the hard drive.
See Alarm Inputs Configuration diagram at the bottom. Use the GND from the alarm block on the DVR and connect to Common of the sensor device. Then using the NO or NC of the sensor device and connect to the appropriate Alarm In 1,2,3,or 4.
Alarm Ouput:Alarm output is used to activate an external device such as a horn or light after an alarm is triggered. To do this the DVR uses a dry contact normally open relay. To configure alarm ouputs, connect the external device to the NO (Normally Open) and COM (Common) connections on the alarm block as required by the device. The maximum contact rating is 24 VDC @ 2 A. Alarm input can start recording only on the camera # that coincides with the alarm input # (cameras 1,2,3,on 4).
