Digital Ally Inc.| DVM Configuration Overview
2-1
Section - 2: DVM Configuration Overview
Many customizable features are available for the DVM-800. The file that is used to update the DVM
configuration is named “deviceconfig”. This file contains all of the necessary wireless settings,
operational settings, and user logins. Section 3 will guide you through the process of creating the
configuration file using the Settings tab within the VuVault™ back office software. You will then save
the file using the Media Card Admin Tab within VuVault™ (Refer to Section 3-11 for details).
Once the configuration file has been created within VuVault, use one of the following methods to
update the DVM:
The DVM must be initially be configured for wireless communication using the SD card method
before Wireless Updates can be utilized.
Using your External SD Card
a. Copy the “deviceconfig” file to a SD card.
b. Install the SD card into the external card slot of the DVM.
c. The DVM will reboot and load the settings from the new configuration file. The old
configuration settings will be overwritten and discarded.
Wireless Updates
a) Once the new configuration is saved in VuVault, go to “Media Card Admin” and click
“Save to Folder”. Navigate to the local hard drive folder to which you wish to save
the “deviceconfig” file.
b) Open the WTM-Lite™program and click the “Update Devices” button, then the
“Deploy Update Files” button. (See the VuVault Wireless Server Setup Guide for
details).
c) Navigate to the hard drive location for “deviceconfig”, click on the file then press
OK.
d) Select the device or devices to update and press “Done”.
e) When the DVM reconnects to the FTP server, it will use settings from the new
configuration file. The old configuration settings will be overwritten and discarded.
If the Recording Mode of the DVM is set to ECA (Evidence Capture Assurance), the DVM will
not make any attempts to wirelessly connect to the FTP server unless there is at least one
Event Recording present on the DVM to be uploaded. In this case, you may make a quick
recording on the DVM to enable WiFi to connect. This will allow a new configuration or
firmware file to transfer from the server to the DVM.
Once the update process has started:
Do not remove power
Do not turn the ignition off
Do not remove the external SD card

Display
LCD Brightness
The LCD brightness is separately adjustable for day and night modes. To use this setting, choose
the desired brightness setting for day and night modes. A light sensor located on the front of the
DVM automatically places the system in the correct mode (day or night). This sensor uses a
sampling filter to sense changes in ambient light; therefore some delay will be present when
switching between the two modes. This is designed to prevent the DVM from switching
unnecessarily when the dome light or car door is opened, for example.
Settings: Day Mode 1-7 [Default =5]
Night Mode 1-7 [Default =5]
The LCD brightness setting can be temporarily overridden by the DVM operator. See page
5-5 for more information.
Record LED Behavior
The Red Record LED behavior is adjustable to accommodate your desired operation when the
DVM is in record mode.
Settings: Off (Stealth Mode), Slow, Medium, Fast, Solid [default]

Power
The Power operation is configurable and specifies how the DVM will operate when the vehicle ignition
is turned to the ON or OFF positions. Two parameters control the power operation in order as follows:
Ignition Shutdown Timer
The Ignition Shutdown Timer specifies the amount of time the DVM remains fully powered when
the vehicle ignition goes from ON to OFF. If set to zero (0), the Ignition Shutdown Timer is not
used and the DVM will then follow the operation for the Days in LPS configuration.
Settings: 0 to 50 minutes, 1 hr, 2 hrs, 4 hrs, 8 hrs, 12 hrs, 24 hrs, and unlimited [default = 30 minutes]
During the Ignition Shutdown Time:
1. The DVM is fully powered and operational, including all high power consumption
devices, such as; cameras (including Pre-Event), recorded audio, GPS, IF Box, LCD
monitor, and the pre-event buffer.
2. The DVM will remain fully powered until the ignition shutdown timer expires. When the
timer expires, the DVM will then follow the operation for the Days in LPS configuration.
3. If the vehicle ignition switches on before the timer expires, the Ignition Shutdown Timer
is cancelled and will start over again when the ignition is turned off.
Days in LPS (Low Power Standby)
When the vehicle ignition goes from ON to OFF the DVM will first follow the operation for
Ignition Shutdown timer and then the operation for Days in LPS configuration. The Days in LPS
configuration specifies the number of consecutive days the DVM will remain in Low Power
Standby before completely powering off.
Settings: 0 to 10 days [default = 0 days]
Using a low power standby configuration ensures the DVM is fully powered on and ready to
record within a few seconds of the vehicle ignition switching on. During LPS:
1. All high power consumption devices will be turned off, such as; cameras (including Pre-
Event), GPS, LCD monitor, ECA recording, and the pre-event buffer. If configured,
Accelerometer, External Triggers, and the Manual Record button events will trigger an
event record. All other triggers are unavailable during low power standby.
2. The DVM will remain in low power standby until the number of days expires. When the
number of days expires, the DVM will completely power off.
3. If the vehicle ignition switches to the ON position before the number of days in low
power standby expires, the DVM will wake up to the full power state and be ready to
record within a few seconds.
The DVM will draw a maximum of 170mA of current during Low Power Standby. Typically, a new
or strong vehicle battery will provide enough current to power the DVM in Low Power Standby
for 5 days without discharging the battery. The vehicle’s battery current rating, battery age, and
other equipment that remains powered on when the vehicle ignition is off will affect the
maximum consecutive days the DVM should remain in Low Power Standby. The following table
When in LPS, “Sensor Only” type IF Box sensors will not turn on the LCD.

Complete Vehicle Power Loss
During an event record, if vehicle power is completely lost to the DVM system, the DVM will
switch to the internal battery to end the event record, close any open files to prevent data
corruption, and then power off after 60 seconds. If the DVM is not recording when vehicle
power is completely lost, the DVM will power down after 60 seconds using the internal backup
battery.
External cameras on the DVM-800 rely on the vehicle power supply. Thus, during a complete
vehicle power loss to the DVM system, no video can be captured from the external cameras.
Settings
Audio Mute
Choose whether to allow or not allow the DVM user to mute the audio while the DVM is
recording.
Settings: Disabled, Enabled [default]
Login Mode
Choose how the user will log into the DVM system. User device logins are configured in the
VuVault Admin>Users tab. Users may log in using their User Name or Device sign on ID. If set to
none, no DVM login will be required (not recommended).
Settings: None, User ID; User Name [default]
Entry Timeout
Enter the number of seconds when LCD menu items timeout from no user input. This timer
applies to the Main Menu and Profile screens. When the timer has expired, the DVM will return
to standby mode.
Settings: 0 to 600 seconds [default = 60 seconds]

3.5 Record
This section defines how the DVM will record audio and video events to the storage media.
Recording Details
Your DVM-800 includes an external 32GB SD card which is normally used as the primary memory
storage. Use the following options in this section to configure your record settings.
Record Quality
The Record Quality parameter allows the video compression bit rate to be adjusted. Digital video
is compressed by taking out data that remains constant from each frame, and only storing data
that actually changes. This allows the file size of videos with still backgrounds to be much smaller
than they would be if the background had to be present in every single frame. The bit rate is the
amount of bits that can be used in one second of video.
The higher the record quality, the higher the bit rate and the size of the event files. The default
setting is “very high” for maximum video quality, but can be lowered to “standard” or “high” to
increase the compression rate and reduce the required storage space (see figure 3-9).
Settings: Standard (512Kbps), High (1Mbps), and Very High (2Mbps) [default]

Record Frames Per Second (FPS)
Sets the number of frames per second the DVM will record. The higher the setting, the better
the video quality, and the larger the size of the event files (see figure 3-9).

File size varies with the Record Quality, FPS settings, and video content. Consult the table above to
determine which settings are best for your application. The data above was extrapolated from 1 minute
video file samples, and were focused on a stationary background. The storage column represents both
channels of video combined together. This is intended as a general guideline and actual compressed video
size will vary based on subject matter.
Event Audio
The Event Audio setting determines how audio will be recorded to your DVM. If “Enabled”, audio
information is recorded both during the recorded event and during the configured pre-event
buffer time. If “Enabled (w/o Pre-Event)”, audio will be recorded during the event but not
recorded during pre-event. If “Disabled”, no audio will be recorded. If the Pre-Event Buffer Time
is set for 0, Pre-Event Audio is turned off.
Settings: Enabled, Disabled, Enabled (w/o Pre-Event) [default]
Pre-Event Buffer Time
This option allows you to set the amount of time for the pre-event buffer, in 6 second
increments. The DVM will buffer the last 6-30 seconds of video prior to the start of the recorded
event so it can be recorded as part of the event. A setting of “0 second” disables the pre-event
function and removes the pre-event audio setting from the Event Audio dropdown menu.
Settings: 6, 12, 18, 24, 30 seconds [default]

Record Mode
In addition to the external SD Card, the DVM-800 has 32GB of internal memory which is
permanently installed in the unit. Select one of the following three modes to determine how the
storage memory is utilized.
1. Internal
All triggered and manual recordings will be saved to the mirror’s Internal
Memory. These recordings will only be accessible by wireless upload to VuVault
or by using the USB cable to connect the DVM to a PC and uploading to VuVault.
In this mode, an external SD card does not need to be present in the DVM.
2. External
All triggered and manual recordings will be saved to the External SD Card. These
recordings will be accessible by wireless upload to VuVault or by manual transfer
by removing the external SD Card and using an SD Card reader with a PC.
3. ECA (Evidence Capture Assurance)
All triggered and manual recordings will be saved to the External SD Card as
above, but, the DVM will also continuously record from the default cameras
(Source 1 and Source 2 as configured in the Record tab) to the Internal memory.
ECA recording will be temporarily suspended during any of the following:
A triggered or manual event is recording.
When the DVM is wirelessly transferring files.
The video playback screen is on or video is being played on the DVR.
ECA will always record in “Loop” mode: When the internal memory is completely
filled, the earliest recording will always be deleted to free up memory for new
recordings.
Settings: Internal, External, ECA [default]
Retrieving ECA Recordings from Internal Memory
Using the supplied USB cable, connect a PC to the USB/WiFi Port on the back of
the DVM and restart the system. Recordings can be selected and uploaded to
VuVault using the Upload feature. Alternatively, the files can be copied to the PC
using Windows Explorer.
If the decision is ever made to switch from ECA mode to Internal Memory mode after having already
used ECA, be sure to upload or manually delete the existing ECA recordings from the internal memory
via USB cable connection to a PC. Failure to do so will cause the DVM to wirelessly upload all of the
existing ECA recordings, which would take many hours to complete.
Event Loop
Use this setting to determine how the External SD Card memory is handled.
1. Select Off (Default setting) to allow the DVM to make triggered and manual recordings
only until the External SD Card is full. No further recording will be possible until existing
recordings are uploaded to VuVault or the full SD card is replaced.
2. Select On for the DVM to operate in “loop” mode. When the external SD Card memory
is full, the DVM will delete the earliest recording to free up memory for new recordings.
In this mode, the DVM will always be able to make new recordings, but will risk the
possible overwriting of an important recording if it has not been uploaded by the time
the SD card becomes full.
Settings: On, Off [default]

Number of Channels
1. Select Dual to configure the DVM to record two camera sources simultaneously when a
recording starts. Both record status icons on the DVM display will be activated when
recording.
2. Select Single for triggered and manual recordings to initially record from only one
camera (Indicated by the upper record status icon on the DVM display). The second
channel recording can then be manually started by pressing the Play/Stop button on the
DVM (Channel 2 recording is indicated by the lower record status icon).
Settings: Single, Dual [default]
Pressing the REC button while 2 channels are recording will stop both channel recordings.
Cameras
The DVM contains two internal cameras and also supports two external cameras. The DVM can record
two video sources simultaneously. You may choose one of the four camera inputs to assign to each
source. The selection you make here will become the default camera selections for all recorded events.
IF Box Input Sensors and the optional backup camera may have their own separate camera
configuration if desired. Consult section 3.8 to review your IF box input sensor configuration.
Source 1
This is the main video channel available for display on the LCD during a recorded event,
and is typically reserved for the 12XC external front facing camera attached to the
External #1 (CAM 1) port on the back of the DVM. Choose one of four available camera
inputs for this source.
Settings: Internal Passenger, Internal Road Facing, External #2, External #1 [default]
Source 2
This is the secondary video channel and is not displayed on the LCD during the recorded
event. If a backup camera is not utilized, choose External #2 to record the external back
seat camera attached to the CAM 2 port on the back of the DVM. If a backup camera is
utilized, choose either the Internal Passenger or Internal Road Facing camera so that the
backup camera image will be switched correctly. Choose one of the three remaining
camera inputs for this source. For more information on backup camera configuration,
see how to configure a backup camera.
Settings: Internal Passenger, Internal Road Facing, External #1, External #2 [default]
IR LED
Choose whether to enable the infrared LED’s on the DVM front panel to aid in the illumination of
the internal passenger facing camera. If set to AUTO, an ambient light sensor located on the
front of the DVM automatically turns on the IR LED’s during low light conditions. Choose OFF to
disable the IR LED’s.
Settings: Off, Auto [default]

3.7 Motion
Accelerometer
The DVM-800 has a built-in accelerometer which can be used to trigger an Event Record when the set
G-Force levels are exceeded. The accelerometer can be used to activate an event recording based on
the independent G-force levels for acceleration, braking, cornering, collision, and vertical movements.
Accelerometer event triggers can be disabled by setting the G-force levels to zero (0) in the
configuration of the DVM. Setting the G-force level greater than zero (0) will set the event trigger
threshold. When the event trigger threshold is met or exceeded, an event trigger will occur and the
DVM will begin an event record. The accelerometer duration parameters determine the amount of time
the G-Force level must be present before triggering an event.
Settings: Low, Normal, High, Disabled [default], Custom

Vehicle Speed
Speed Source
The vehicle speed can be used to trigger an event record. Vehicle speed can be calculated
through the use of the supplied GPS antenna, or by utilizing the Vehicle Speed Sensor (VSS)
signal. The Vehicle Speed Limit can then be adjusted to the speed at which an event record
should occur. Select None if an event record is not required when the vehicle exceeds the speed
limit.
Settings: None [default], Sensor 4 VSS, GPS
When Sensor 4 VSS is selected as the Speed Source, the Sensor #4 settings will automatically be
configured as an Event Trigger as shown in the IF Box Input Sensors screen below. The IF Box
Sensor 4 input wire must be connected to the Vehicle Speed Sensor output to utilize VSS.
When the Speed Source is set to None, no event trigger will occur when the Vehicle Speed Limit is
exceeded, however the vehicle speed is still calculated using GPS and is logged into the metadata
for all events that are recorded.
VSS Pulses per Mile
Input the number of VSS pulses that are generated during one mile of vehicle travel. This varies
by the make and model of the vehicle.
3.8 Sensor
The Interface Box (IF Box) is an external module that allows connection to vehicle sensors and triggers.
The IF Box provides the DVM system with the capability to add common event record triggers such as
emergency lights, reverse, vehicle speed sensor (VSS), brakes, or other sensors. In addition, the IF Box
provides connectivity from the vehicle power system to the mirror, communicates with the mirror using
a CAN bus interface, and provides external connection for extending the CAN bus to other Digital Ally
devices.
When adding a new DVM or IF Box, or when either is replaced, always perform a firmware update. The
firmware update will ensure that the IF Box has the correct version installed. Refer to Section 10 for
firmware update instructions.
