Wake on Alarm Feature Wiring (Optional)
When the Wake on Alarm function is enabled, if alarm 0 is triggered, the system powers up and starts
recording. The system takes about one minute to power up and start recording, depending on environment
conditions. This circuit activates with the application of 12 volts to the red wire in the two pin Alarm 0
socket on the back of the DVR.
To wire the Wake on Alarm feature:
1 Connect the DVR’s back panel alarm input harness connection (2 pin) so that pin 1 (red wire) is toggled
to a 12-to-24 VDC source to trigger power.
2 Connect or remove the black wire of the alarm input harness.
3 In the DVR Alarm Settings configuration menu, configure as follows:
• Select Alarm 0
• Set the Alarm Duration (1, 5, or 10 minutes)
• Set the Alarm Input:
• If programming this line as normally open (N.O.), the red wire can attach directly to the 12V
trigger, no further connections are required.
For example, if the alarm input was connected to interior lights of the vehicle, the wake
function would occur if the lights were turned on. If the lights remain on, the DVR will still
only record for the duration specified in the Alarm menu.
• If programming this line as normally closed (N.C.) the red wire must remain at ground when
off and trigger on with 12V.
For example, if the alarm input was connected to interior lights of the vehicle, the wake
function would occur if the lights were turned on. If the lights remain on, the DVR will
continue to record, repeatedly triggering Alarm 0. Do not use this setting if e-mails are to be
sent based on Alarm 0.
This input CANNOT be left floating, and must be pulled back to a 0 VDC low condition via
external resistor or relay.
• Set the pre-alarm record duration (Off, 5 sec, 10 sec.)
• Set the Email option (On, Off)
• Set the Wake option to On
CAUTION
The Wake on Alarm starts booting up the DVR when an alarm is detected. The DVR takes about 1
minute to boot up before it can begin recording. It cannot instantly capture the alarm event.
