DVR Installation
DVR Unit Mounting
The DVR unit is the core of the Recording System. All system connections go to the DVR unit. The storage device (SD
Card or SSD) is located inside the DVR unit. A good mounting location is important for the DVR unit as its location should
be readily accessible for viewing status, removing the disk, and ideally for reducing system installation time.
Choosing Mounting Location:
The DVR unit itself is small and can be mounted in varied locations. The black lockable mounting cage has four (4) pre-
drilled holes for mounting; however, additional holes can be drilled in the mounting cage to provide better attachment to
the mounting surface.
Things to consider when choosing mounting location:
•Access to the front of the DVR to view lights and/or remove storage media.
•Access to insert and turn the key to remove cover, should test for accessibility as necessary.
•Access to the rear of the DVR for service purposes.
•Locate all structural elements that may make it difficult to run wires. Avoiding these by choosing a good mounting
location saves installation time in addition to better usability.
•Proximity with other Radio Frequency (RF) devices, such as two-way radios and computers, must be 6” or more.
•Cable routing for power, GPS, Event Marker Button, triggers, and cameras.
•Fastening to mounting surface and what is behind it.
Recommended Mounting Locations:
•Front overhead compartment above windshield: Mount to the driver’s
side for easy cable routing.
•Compartment above the driver: Place locking enclosure and use the
key to ensure easy access.
•Under the first seat behind the driver: Mount inverted directly to the
seat bottom.

Installing Power Cable
The power cable provides power to the unit and controls when it is on or off. Make sure the primary battery power
connection is to a reliable 12V-24V DC power source. The cable may be routed from either direction.
RED
Fused 12-24V DC Battery Power: The battery power wire should be connected to an
always-on power supply on the vehicle. The connection should include a 3A fuse and
be on its own dedicated circuit. If possible, connect the unit directly to the positive
terminal of the vehicle’s battery through a 3A fuse.
GREEN
Key ON Ignition Signal: Signals the unit that the vehicle is ON. It can be connected to
a 12-24V DC ignition source (Fused), or to a ground level ignition source. If using a
ground level ignition source, the wire must first be connected to a 12V source and the
setting for “Ignition Level” changed to LOW in the power menu.
BLACK
Chassis or Battery Ground: The ground wire connects directly to a clean grounding
stud/screw or directly to the negative terminal of the battery.
IMPORTANT: Do not connect the red battery power wire to a battery drain protection device such as a ChargeGuard®; this can cause abnormal
performance and/or damage the electronics inside the recording unit. The unit itself has a battery drain protection function built in.
You must use fuses that can handle the current draw of the unit with all cameras and accessories. With the DVR unit, 8 cameras,
GPS, Event Marker Button, and a Solid-State Disk (SSD) the current draw is ~3A at 12 VDC.
The power cable includes (2) fuse holders with 3A fuses that are intended for use when making final connections to the vehicle to
protect the power cable and the drive recorder unit. Other suitable fusing methods with appropriate amperage fuses may be used
instead of the included fuses.

Analog HD Side Camera Installation
The AHD Side Camera (Kit P/N: DVR-920, Camera P/N: PC-1920) is designed to
provide coverage around the outside of the vehicle. The camera is waterproof rated IP-
67 and has a wide-angle lens that can capture a wide area around the outside of the
vehicle. The camera is designed to be mounted directly to a vehicle exterior body panel.
The camera has six (6) infrared (IR) LED’s that provide illumination during low light/dark
conditions. The camera also has a waterproof microphone built into the camera housing.
The camera lens has a wide 145° horizontal and 80° vertical coverage.
Mounting Locations:
The camera’s wide field-of-view allow flexible mounting in either a down facing
or rear facing configuration while still providing very good coverage of the side
of the vehicle. For down facing general recording applications, the camera is
typically mounted directly to the roof or side of vehicle body near the roof
facing outward perpendicular to the direction of vehicle travel at a downward
angle. The camera should be mounted as close to the outside edge of the
roofline as possible to prevent blind spots directly next to the vehicle. For rear
facing applications utilizing the camera to cover blind spots in combination
with a monitor, the camera should be mounted as far toward the front of the
vehicle as possible. When mounting to the vehicle, consider spray and debris
from the tires could affect the camera image, so it is recommended to mount
the camera a minimum of 3 feet off the ground to help prevent this. Always
check the mounting structure under the camera for proper access to route the
cable.
Installation:
1. Remove the four (4) Allen head cover mounting screws from the camera and then remove the camera ball and
cable.
2. With just the camera base and gasket, hold in desired mounting location and mark the three (3) camera base
mounting screw locations and the center of the cable exit hole in the base.
3. It is recommended to power on the DVR unit, temporarily connect the camera to it, set the camera in the
mounting base (with gasket attached), and observe that the view in the desired mounting location is satisfactory
before permanently attaching the camera and routing the cable(s).
4. Before drilling holes, ensure there is adequate clearance for mounting screws and cable routing clearance.
5. If you are certain of the cameras mounting location, drill the center cable hole with a 3/4” or 7/8” drill bit, and it is
also recommended to predrill the three (3) mounting screw holes with an 1/8” drill bit.
6. Route the camera cable through the base and gasket, and then through the cable hole in the mounting surface.
7. Use the mounting hardware provided to attach the camera base to the mounting location.
8. Attach the camera cover to the camera with the four (4) Allen head mounting screws. Leave the screws slightly
loose until the camera is aimed.
9. Power on the DVR unit and connect to the Wi-Fi to view the live camera image to properly aim it on the view
page. (See Viewing Cameras on a Smart Device for connection details)
10. After the camera is aimed, tighten the four (4) Allen head mounting screws to lock the camera aim.

Analog HD Marker Light Camera Installation
The AHD Flush Mount Camera (Kit P/N: DVR-910, Camera P/N: PC-1910) is designed to be
mounted in an existing 2” or 2.5” marker light hole in the rear body of the vehicle to replace a
standard 2” or 2.5” marker light. The camera is used most often as a backup camera and replaces
a marker light in the rear bumper. This camera is primarily used because it does not require any
holes to be drilled in the vehicle body and is typically very durable because the marker lights are
typically mounted in a protected area on the rear of the vehicle. The camera lens has a wide 145°
horizontal and 80° vertical coverage.
Mounting Location:
The camera mounts in an existing marker light hole. The camera can be rotated 360°
for proper aim but cannot be tilted at an angle. If possible, the camera should replace
the center most marker light to provide the driver with the most natural view.
Installation:
1. Locate the desired mounting location, remove the existing light to check for
proper clearance for the camera body.
2. Disconnect the wiring from the original light, then remove it and the grommet.
3. Assemble the camera to the light assembly using the 4 mounting screws.
4. Install the new grommet into the hole. For 2.5” light applications, first install the larger
grommet into the hole, then install the smaller grommet. (As shown below right)
5. Connect the red 12V LED power wire and black ground wire from the light assembly to
the existing wiring through the grommet.
6. Slide the camera cable into the hole in the back of the grommet.
7. Connect the camera connector to the cable running to the DVR unit, if it is not yet
installed, install the cable at this time.
8. Press the camera light assembly into the grommet and rotate the camera until the white
dot is at the top.
9. Power on the DVR unit and connect to the Wi-Fi to view the
live camera image so it can be properly adjusted to level by
rotating the light in the grommet. (See Viewing Cameras on
a Smart Device for connection details)

Analog HD Low Profile Camera Installation
The AHD Low Profile Camera (Kit P/N: DVR-912, Camera P/N: PC-
1912) is designed to be mounted in the rear of the vehicle. It is very low
profile, allowing it to be mounted at the top of the rear for easier wiring
and better field of view. The camera mounting hole pattern matches
that standard 7” on center spacing of US license plates for easy
mounting over license plates for light duty vehicle applications where
space is limited, or drilling holes is not desired. The camera has four (4)
infrared (IR) LED’s that provide illumination during low light/dark conditions. The camera also has a waterproof
microphone built into the camera housing. The camera lens has a wide 145° horizontal and 80° vertical coverage.
Mounting Location:
This camera is often used on the outside rear of light duty vehicles like cars, vans, and SUVs to provide video capture of
backup incidents and observation behind the vehicle. The camera can only be mounted to a horizontal surface, it is
designed to be mounted directly to the mounting surface and can adjust up and down for proper aim. The camera
mounting screw holes spacing allows direct mounting to US license plate bolt pattern.
Installation:
1. Locate the desired mounting location of the camera. It is
recommended to power on the DVR unit and temporarily
connect the camera to it and observe that the view in the
desired mounting location is satisfactory before
proceeding to the next step.
2. When the desired mounting location is found, mark or
measure the two (2) mounting screw hole locations in the
camera. If license plate mounting, skip this step.
3. If the cable will be routed through the vehicle body, it is common to drill a ¾” hole behind the camera where the
cable exits the camera body, mark and drill this hole if needed. Remove any burrs from the hole to prevent
damage to the cable. If license plate mounting, there is a notch in the top left of the camera for the cable to exit
and then route into the body of the vehicle.
4. Route the camera cable into the hole and then install the camera to the marked locations from step 2. Attach the
camera with the supplied mounting hardware.
5. Route and install the extension cable(s) to the cameras final
mounting location and connect it to the camera. Leave enough
slack to allow removal of the camera to simplify service in the
future (typically 4”-6”).
6. Power on the DVR unit and connect to the Wi-Fi to view the
live camera image to properly aim it on the view page. (See
Viewing Cameras on a Smart Device for connection details) To
adjust the camera aim, loosen the two (2) small Phillips head
screws on either side of the camera assembly.
7. After the camera is aimed, tighten the two (2) Phillips’s head
adjustment screws.
