POWER INPUT AND RELAY CONTACT
These connectors are used to connect the input power and the event
marker to the DVR400 system.
The Event Marker connector is used to connect the event marker
box which 247 Security Inc. has available. This contains 2 LED’s to
indicate “Video Lost” and “Recording.” The event marker also has a push
button, which can be pressed to mark the video files at that specific moment. Pre and Post-
locking is controlled by the DVR configuration within the Client software.
DC IN: This signal supplies the main power to DVR400. The input DC voltage
operates from 8V to 26V maximum. Please ensure that you do not exceed this range.
ON/OFF: Typically this line connects to the vehicles ignition. The DVR400 uses this
line to trigger the power shut-off delay and the timing circuitry. The DVR400 will remain ON
until the shut-off delay time has been reached. The system will then go through its normal
shutdown procedures before completely powering down.
GND: Common DC ground. Please make sure that all “GND” get the same common
ground from the vehicle.
