CAUTIONS & NOTES
Please read and follow the instructions and precautions in this installation guide when installing
the DVM-750 system.
For assistance, a qualified installation technician or mechanic should be consulted.
Do not route wiring and cabling over sharp metal edges where they may become
damaged or cut.
To prevent electrical shorts or breakage in the wiring and cabling, do not allow wiring
and cabling to be pinched behind trim pieces, panels, etc.
Do not run wires or cables in areas where they become damaged by heat from the
engine or the exhaust system.
Do not install any in-car video system components or wiring in the deployment path of
the air bag(s).
Do not connect any Digital Ally wiring to a charge guard or battery saver system.
When installing the cables or making wire connections, it is recommended you allow for
service loops and leave a little ‘slack’ in the cable connections to allow for service loops
and to allow for movement of the mirror so the connections do not get pulled or
accidentally disconnected.
Avoid running cables parallel to other wiring and/or antenna coax of other systems that
may be installed in the vehicle and do not leave excessive cable above the headliner.
Doing so may cause Radio Frequency (RF) interference in the video or audio recordings
of the DVM system.
If installing the optional wireless transfer module or VuCommand MDT interface,
consult the WTM-555 installation instructions, and the VuCommand installation
instructions located on your product DVD.
DVM-750 Interface Box Backup Battery
This system is equipped with a Backup Battery that is located in the Interface Box (pictured on
page 16 of this manual). In case of vehicle power failure, the Backup Battery will maintain power
to your DVM-750 system for 30-90 minutes. If the Backup Battery does not have a high enough
charge at the time of installation, the DVM-750 system may not turn on correctly the first time. It
may be necessary to charge the Backup Battery.
**To charge the Backup Battery, install your DVM-750 system, but do not turn it on. Start
the vehicle and allow the vehicle to idle for 5-10 minutes.

SYSTEM INSTALLATION
The current factory rearview mirror must be removed from the windshield mounting plate. There
are several versions of mirror mounting systems. Below are the most common methods of
rearview mirror removal. Do not use excessive force when removing the mirror from the
windshield. The mirror mounting plate may become separated from the windshield and/or the
windshield may break if excessive force is used.
Use one of the following methods below that matches the mirror mounting configuration of your
vehicle:
1. Using a Philips screwdriver or #20 Torx bit, loosen the screw in the base of the mirror.
2. After loosening the screw, gently lift upward to slide mirror off of mirror mount.
2011-2012 Dodge Charger Rearview Mirror Removal
1. With your right hand, grip the mirror and keep it stabilized.
2. With your left hand, grip the base of the factory mount where it meets the glass.
3. Gently apply a small amount of additional inward force toward the glass and rotate the
base clockwise.
4. The spring loaded factory mount should release from the windshield4 puck. See picture
below.
1. Remove front passenger side threshold.

2. Pull the door seal away and carefully remove any side trim pieces.
3. Remove the passenger side front interior A-pillar cover.
4. Remove the passenger visor clip with #20 Torx screwdriver or Phillips screwdriver
depending on your vehicle.

DVM-750 Installation Guide 860-0008-00 Rev C
Digital Ally, Inc |DVM-750 Installation Guide

5. Remove the passenger side kick panel & pull back the carpet to expose the vehicle
chassis.
1. Attach the mirror mount directly to the back of the DVM with four #4-40 x ½” pan head
screws and four #4 split lock washers shown below. Attach the lanyard to one of the top
two screws and attach the other end to a structural rib underneath the headliner of the
vehicle.
2. To tighten the Big Ball DVM Mount, use a 7/64" hex key wrench or driver to tighten the
two screws on the socket that are loose.Start by tightening one screw 1/8" of a turn
maximum. Warning: Do not over tighten the hex locking screws in the middle of the Big
Ball mount or the DVM may break off the windshield when adjusted, possibly causing
damage to the windshield.
3. Check how tight the DVM mirror mount feels. If it is still loose, tighten the other screw
another 1/8" turn. Continue this process until the DVM has the correct feel. If the other
socket is also loose, perform this same procedure on the other socket. The socket
nearest the windshield should be tighter than the socket nearest the DVM, i.e. the socket
nearest the DVM should move before the socket nearest the windshield moves. Also
keep in mind that if you are making this adjustment when the ambient temperature is
high, the mount will become tighter as the temperature decreases.
Step 3: Attach the Big Ball Mount

DVM-750 Installation Guide 860-0008-00 Rev C
Digital Ally, Inc |DVM-750 Installation Guide

1. Attach the following cables to the back of the DVM: GPS, I.F. BOX, CAMERA 1, AV,
and CAMERA 2 (if purchased). Also, connect the USB if the wireless option was
purchased or if manual download to laptop is desired, and connect the ETHERNET
adapter cable if the “VuCommand MDT interface” option was purchased.
2. Attach the mirror to the windshield. Secure your DVM to the vehicle windshield. For 2011
or 2012 Dodge, attach and orientate the adapter to factory windshield as shown below.
Use Loctite™to secure the adapter to the factory windshield mounts. Attach optional
drop down bracket as shown.
In some vehicles, the factory position of the manufacturer’s windshield
mounting plate may not allow for proper rearview DVM adjustment. The
mounting plate included with the DVM-750 package can be glued to the
windshield in a location that will allow proper adjustment. We
recommend Loctite 03346 for installation of the mounting plate.
DO NOT glue mounting plates to the black coated portion of the glass.
3. Route cabling along the roofline and down the A-pillar. Leave enough slack in the cables
as a service loop for the rearview mirror adjustment. Then you can begin routing the
cables under the front edge of the headliner towards the passenger side of the vehicle.
Continue routing the cables down the windshield pillar below the dash. Secure the
cables together with tie wraps every 8 to 12 inches. To conceal the cable it may be
necessary to loosen the sun visor mounting bracket and/or other trim pieces to allow the
cable to be tucked in behind the headliner.
Step 4: Mirror Connections

Front Camera
Install the visor mounting plate and then re-install the sun visor clip which holds up the
visor mount. The visor mount has a slot and three sets of screw holes for various
adjustments if necessary. Attach the camera to the plate. The camera can also be
installed onto the windshield by gluing a mounting puck to the windshield.
Rear Seat Camera (optional)
1. Determine a mounting location for the auxiliary rear seat
camera. The example below has the camera mounted in the
center of the cage along the roofline. This gives a wide
angle view of the entire back seat.
2. Route the remaining portion of the camera cable to the
external surface mount camera and connect. Secure extra
cable in the headliner away from any other existing cabling
and/or airbags.

Backup Camera (optional)
Digital Ally offers two different backup camera models for you to choose depending on
your application and/or vehicle. The camera may be connected to the back of the DVM
either by using the CAM2 port, or the A/V input through the dongle cable. Refer to the
diagram below for cabling options. You may also need to use an extension cable
depending on your vehicle. Cable part numbers are located on page 5. In order for the
backup camera to function correctly, you must also connect to the vehicle’s reverse gear
signal (see Step 7).
Cabling OPTION 1: Using the CAM2 input Cabling OPTION 2: Using the A/V input
1. Route the Camera Cables
a. Review the diagrams above depending on which camera and cabling option you
have purchased. Start routing the cable from the DVM and work your way back to
your designated camera location.
b. Leave slack in the cable as a service loop and for DVM adjustment; then begin
routing the cable to the rear of the vehicle.
c. Depending on your vehicle you may be able to route the cables down the side of the
headliner to a rear compartment of the vehicle. Otherwise find a suitable route on
the floorboard of the vehicle.
d. To conceal the cable it may be necessary to loosen interior trim and other
components within the vehicle.
e. Secure the cables using Velcro or standard tie wraps as required.

It may be illegal in your local area or state to cover up the State, County, Year, etc. on the vehicle
license plate. Depending on the design of the license plate for your particular state, you may need
to use the Side Mount camera bracket included in the kit in order to ensure compliance with your
local and state laws. This bracket is designed so it can be mounted behind the license plate
when installing the backup camera.
EXTERNAL MOUNT BACKUP CAMERA
a. Identify a flat surface to attach the mounting bracket.
b. For exterior mounting where the cable must be routed through a
panel to the interior of the vehicle:
i. Position the mounting bracket, locate the ¾” hole in the
bracket, and mark the center on the mounting surface.

DVM-750 Installation Guide 860-0008-00 Rev C
Digital Ally, Inc |DVM-750 Installation Guide
15
ii. Place the bracket aside. Prepare the center mark on the mounting surface
using a hold punch, and then drill the hole using a ¾” drill bit.
c. Using the camera hardware provided:
iii. For installations with a ¾” cable hole drilled through from the exterior to the
interior of the vehicle, the black mounting grommet and gasket should be
used to provide a weather resistant seal between the vehicle surface and the
camera’s mounting bracket.
iv. Install the camera bracket to the vehicle (see picture below).
v. Attach the camera to the mounting bracket.
3. Connect the Backup Camera
a. The pigtail from the Backup Camera will connect to the camera cable routed from the

The external Rear Microphone cable should be routed to the rear of the vehicle and is usually
placed covertly on the roofline door seal near the cage. Connect the External Rear Microphone
to the Input labeled “EXT MIC” on the 24” AV Dongle Cable and wrap the connection tightly with
electrical tape.
Rear Microphone AV Dongle Cable
The magnetic GPS antenna/receiver can be placed in the corner on the front or rear dash of the
vehicle, or mounted externally if desired. Use high quality Velcro or double-sided tape if
mounting internally. Connect the GPS antenna cable to the GPS INPUT connector on the back
of the DVM system. Optionally, the antenna/receiver can be mounted on the outside of the
vehicle if better reception is required.
GPS antenna
Connect the power and sensor input wiring harness (11-wire, 14-pin, multicolored) to the
interface box and follow the included wiring chart on page 14 to connect the desired optional
inputs and record triggers. Insert the two 7.5 AMP fuses into the slots located on the side of the
interface box, as shown in the picture below.
It is recommended that these connections are made
directly to the police package accessory harness or engine
compartment battery wiring harness for best results. These wires
should be used ONLY for the DVM system and not be tapped
into for installation of any other equipment in the vehicle. Doing
so, could result in possible radio frequency interference from the
other equipment. Do not connect to a charge guard or battery
saver system.
It is highly recommended to install the provided 7.5 Amp fuse
and holder on the Red +12V power source wire. Doing so will
provide the proper protection for the wiring between the source and the
device.
