LE / Public Safety Installation Instructions




These instructions provide the knowledge needed to successfully install a Pro-Vision Video Camera System into a Law Enforcement vehicle. The installer must have a minimum level of experience working in and around mobile 12VDC applications. Utilizing your experience and the information contained here, you should be able to safely and successfully install Pro-Vision Video Camera System into any public safety vehicle.

These instructions primarily reflect Pro-Vision’s newest system, the LE Ranger, however, the same concepts should be applied to the installation of older systems, such as the PD-1800-HD or PD-1900 Hybrid DVRs. Any slight differences in programming information can be found in the specific system guides for each model.


1. Go over the first vehicle with the customer. Discuss requirements and likely/desired locations for Pro-Vision components: cameras, DVR, event marker button, wireless microphone charger, and, if applicable, any specific operating or programming needs.

(A) Confirm DVR Mounting Location. The DVR must be minimally accessible to remove the SD card or SSD when needed. The location must also account for the length of the current Wi-Fi or cellular antennas, which must be window mounted and connected to the DVR. Suggested or desired mounting locations of the DVR include a trunk-mounted public safety equipment tray, the rear-side of the cargo barrier in an SUV, rear-side trim panels, the front-side of the front prisoner partition, behind the front passenger seat, the rear of the equipment console, or other customer directed locations.
(B) Confirm Camera Locations. Cameras must provide a maximum view of the targeted area, maintain safe mounting practices to avoid injury to the vehicle occupants in the event of an accident, and not interfere with existing systems. 
(C) Confirm Wireless Mic Pack Location. The usual mounting locations are on the rear of the equipment console or the passenger side of the console. Factors like computers, computer stands, rifle racks, mobile printers, moveable armrests, and radio/siren microphones must be considered. NOTE: If the LE customer has, or is getting Pro-Vision BC4 Body Cams, they may not need or want the wireless pack installed.
(D) Event Marker Location. These are usually mounted somewhere on the equipment console. Consider any mic cables, radar remotes, cellphone chargers, or other equipment when selecting a mounting location.

2. Make sure the customer understands that unless all installation vehicles are exactly the same, you may have to make changes to the equipment location to accommodate any differences in the vehicles. If the customer has multiple vehicle types, you may have to review more than one unit with a customer to make the best plan for the installation(s). 

3. Confirm with the customer the specific programming of their Pro-Vision system: 
(A) Do warning lights trigger to activate on levels 1, 2, and 3? 
(B) Is audio and video always on or set for event only? 
(C) Is EVT programmed for event or alarm recording?
For one or multiple cameras
(D) Is the customer getting SecuraMax, and do they have the SSID, password, and URL for you to complete their DVR programming? 

4. Audit the equipment sold to the customer before you start the first vehicle. Report any shortages to Pro-Vision ASAP so they can ship any missing items needed to complete all installs. 


1. Locate the required power connection points. The Pro-Vision system requires a B+/Hot source, an ignition source, and a ground connection. Most modern police vehicles will provide upfitter wiring for this purpose. It is highly recommended that you connect the specific upfit guide before making your connection. The wire connection points listed below may vary slightly from one model year to another.
(A) Ford Utility or Sedans: Consult Ford Upfitter Guide Online.
• A chassis ground and +B source in the rear or in/around the second seat area. The +B source is a heavy terminal plug enclosed in a red box. 
• The upfitter plugs in the front console area between the front seat have blunt cut leads.


(B) Dodge Charger: Consult Charger Pursuit Upfitter Guide Online.
• Ground plug in the center console area.


(C) Chevy Tahoe: Consult specific model year Guide for exact information and Owner’s Manual.
• Upfit Harness between front seats - SEQ6J1 (cable/harness number from GM).
• See X51AX, wiring diagram on page 50 (found in Chevy's Upfit Guide for the Chevy Tahoe-Police package).


(D) Dodge Durango: Consult Chrysler Upfitter Guide - wiring is similar to Dodge Charger.
• On non-standard vehicles, consult the owner’s manual. Pre-existing public safety equipment, radios, switchboxes, and computers may also affect your B+, ignition, and ground connections. Don’t overload sources.

2. Locate the source for the warning light trigger. 

There are many types of warning light systems, from basic toggle switches to modern, programmable smart siren systems. All these systems provide an active output to turn the warning lights on when activated, either singly or in progressive stages (i.e., a slide switch). Most siren/switchbox systems have progressive switching, either a slide switch or progressive buttons, usually labeled as Level 1, 2, and 3.

3. Unless otherwise specified in Form C specs, the Pro-Vision DVR T1 trigger input must be connected to an output(s) that provides the needed +12VDC during all three active levels.

(A) How to Connect the T1 Trigger with Diodes

When the warning light circuit is energized:


Correct installation of the diode:


Correct installation of the diode:


Incorrect installation of the diode:


(B) Front Mount Sirens: A front mount siren/switchbox is an all-in-one unit with controls on the front and the input/output connections on the back. Using a voltmeter, find the output on the rear that provides +12v when all three levels of the slide switch are active. 

(C) Remote Mount Sirens: These are two-part sirens/switchboxes. Locate the portion where the actual warning lights connect to. The remote unit can be in the rear of the squad, on an equipment tray, or buried in the front console. As with the Front Mount systems, locate the output(s) that provide 12 volts when all the levels are active. Verify this by using a voltmeter to confirm that it is a stable +12v output when active. Be aware that on Smart Siren systems, some outputs may be programmed to provide a pulsing/flashing signal to smart LED light heads. This is not a good signal for the T1 DVR trigger. Also, know that not all sirens may be programmed the same, even for the same customer. An output that will provide the required trigger on one squad may not provide the same on another squad. Always check and verify trigger sources with a meter on every vehicle.

(D) Special Circumstances

(D1) Some light control systems may be programmed to activate the warning lights in a non-progressive fashion. The level 1 switch output may only be active in L1, not L2 or L3. The level 2 output may be active only in L2 or progressively in L3. If you cannot find a single active (+12V) output on the siren/switchbox during all ON levels of the slide switch, it will be necessary to utilize isolation diodes for the trigger connection.

An isolation diode is a one-way switch, allowing voltage to pass through one way but not back the other way. Locate the individual outputs on the switch box that will provide the +12V during each level of activation needed. Connect a diode from each of these circuits that will tie together to provide the required trigger for the DVR. Typically, on an isolation diode, the side with the white stripe is the side that will be connected to the T1 input on the DVR.

HINT: When using a voltmeter, look for +12V on one side of the diode when the other side is connected to an active circuit. If you see +12V, the diode is correctly in the circuit. If you don’t see any voltage, reverse the diode.

Tie the unterminated legs (the white stripe sides) of the diodes together, and this will be the input to the T1 trigger. If installed correctly, each output will supply +12V to the T1 trigger when active, while the other diodes will block that voltage from feeding back into the other warning light circuits.

(D2) There may be situations where all the Smart Siren outputs have been programmed, so no usable outputs will provide +12V in any or all output levels. If this occurs, contact Pro-Vision Install-Tech support. You may be required to have the law enforcement agency contact their upfitter to provide programming changes to the Smart Siren to create the output needed to properly interface with the Pro-Vision DVR. 

4. Mount Your Cameras. 

(A) Front Window Camera Mount. Generally mounted behind the rear-view mirror on the passenger side, where it doesn’t obstruct the driver’s view. Public Safety items like radar antennas or interior lightbars must be taken into account. 

(B) Prisoner Compartment Camera. Generally mounted at the top center of the front prisoner shield. If there is no prisoner shield, the camera will mount to the center of the headliner or possibly on the driver’s side, if safe to do so.

(C) Rear-Facing Camera. If the vehicle is a sedan, affix the mount to the rear window or deck. If in an SUV, the camera would mount either on the rear hatch or inside the squad. The second location is recommended because it allows the camera to cover the rear of the vehicle, even when the hatch is open. (Hatch mounting results in the camera recording the sky if it is open.) 

(D) Outside, Driver, and Passenger Side Cameras. The side cameras mount on the roof of the vehicle, so specific mounting locations will depend on several factors. The actual footprint of the camera versus any roof structural ribs will determine the location for mounting, as will lightbars, LPR systems, and the interior edge of the vehicle, which has multiple layers of metal. You must not attempt to drill through the area that is comprised of multiple layers of metal. In some cases, outside cameras may have to be mounted in front of lightbars or at the extreme rear of the roof. Pro-Vision provides an adapter bracket solution allowing the cameras to mount more toward the vehicle's roof edge.



5. Mount your DVR.

Depending on the chosen location, utilize factory-provided screws or nuts and bolt the DVR mounting cage as needed for safe installation. The requirement is that no sharp screw ends should be exposed in areas where they can injure someone or catch on a customer's equipment, such as in the case of using #8 self-tap screws on a trunk-mounted slide-out equipment tray. 

6. Run Wires and Cabling.

(A) Wires that run in the roof/headliner area must route between the vehicle body and side curtain airbag at A, B, C, or D pillars on the vehicle to prevent Pro-Vision wiring from interfering with the side curtain airbag deployment if the vehicle is in an accident. Visualize how the airbag will deploy and ensure none of your wires/cables are in that path.

(B) Wires that run in the floor area must not be located where they will be pinched or crushed. Be aware of pinch points from prisoner seats, prisoner shields – front or rear, clips on vehicle trim pieces, or kick panel retaining clips. Take into account front seat travel if you need to route wires under the front seat and console. 

(C) Make sure you provide enough slack on the LAN Cable to consider the articulation or travel of any docking station when connecting to the customer’s PC.  

7. Excess Cable Storage. 

(A) Provide enough slack at the DVR end to allow customers to move/access the DVR as needed. Try to keep all cable lengths uniform so there are no wire bundles by the DVR. Find a location where excess cables can be safely stowed out of the way of other customer equipment. Try to organize the cables individually to avoid a “rats’ nest” of wires.

(B) Excess wires and cables should not be bunched up underneath the vehicle carpet where people put their feet or where they will be exposed to water. Storing excess cable under a factory rear seat is discouraged, as the seat itself and any passenger will crush the cables.

(C) Camera cables should be run with sufficient slack to allow service/replacement of cameras. For ceiling-mounted cameras, the excess cable can be neatly looped in the ceiling above the headliner and away from side curtain airbags.

8. Make your fused power and trigger connections to previously located sources.

9. Special Note: If required to install the wireless mic pack, you will utilize the AV1-2 cable with the breakout jack for the wireless mic audio. Tie the blue wire from this cable with the yellow T1 trigger lead. Connect the brown wire from this cable to the T3 trigger input. During programming, you will designate the T3 input as MIC and the program as an active low input.


The Pro-Vision DVR System Guide(s) provides the most detailed information needed to program the various functions for the LE video system, but in general, proceed through the following steps: 

1. Power on the DVR.

2. Locate the DVRs default SSID among the available Wi-Fi sites with your PC and connect to it. 

3. With a web browser, like Chrome, connect to IP address

(A) The Username is:  admin
(B) The Password is:  doesitall 

4. Go to the Live View page at the top of the program and verify that all cameras are working. 

5. While on the Live View page, you can adjust the aim of all cameras as needed to get the optimal camera views. If required, switch to the camera settings page under the Settings Menu to flip any camera's vertical or horizontal aspect. NOTE: The Outside Side cameras require that the horizontal setting be enabled to allow correct viewing of the video with respect to the front and rear of the vehicle. 

6. Go to the Settings Menu and proceed with the main programming of the DVR with Form C/customer specs. Remember that you must hit the Apply button (Apply=Save) on each page for the changes to take effect.

(A) First, go to the System Info page and verify that the DVR is running the latest firmware version. Install the latest firmware version if required. 

(B) On the Power Settings page, set Stop Recording and Power Off delay times. 

(C) On the Date & Time page, set the correct date and time and the correct time zone. (Make sure your PC is set to the correct time zone when you sync time on the DVR with your PC.) 

(D) On the Camera page, re-check all camera views for proper orientation. 

(E) On the Recording page, set bitrates and framerates per Form C specifications. Any special audio or video conditions will also be made on this page. An example would be when the customer wants audio to be recorded only during active event triggers.

(F) Verify that the GPS settings are correct for the customer, MPH vs. KPH, the correct baud rate for DVR. 

(G) On the G-Force settings page, calibrate and program any motion trigger per the information on the page. 

(H) On the Trigger page, the program triggers per Form C. 

(H1) Program T1 trigger for warning lights. Set T1 to display “LTS” and select which cameras will alarm record when activated.  

(H2) If a law enforcement customer has Pro-Vision BC4, Body Cams, enable the Remote Device Activation feature by checking the last box on the right side of the T1 trigger line. Enable the RDA for any other trigger as specified in the paperwork. With this activated, the DVR will signal the Body Cam to start recording when the trigger is activated.   

(H3) Advise the customer that the in-vehicle alarm trigger will start the BC4 recording, but it will NOT turn it off when the trigger is turned off. The user must physically turn off the Body Cam recording. 

(H4) If the system utilizes the Wireless Mic Pack, trigger T3 must be programmed to set the T3 level to LOW. Designate the T3 to display “MIC” when active. Select the desired cameras that need to record when activated. 

(H5) Program the EVT switch function as Event Marker, Record Control, or Alarm Recording Control. Enable the audible beep if required. If set for Alarm recording, it is highly recommended to enable the beep. 

(H6) If the system is to get a vehicle speed Alarm trigger, set the max speed and select which cameras will record. 

(H7) Program the pre-event and post-event times per Form C. These will set the time that an Alarm video will start and end before and after a trigger is turned on and off. 

(I) On the Unit Info page, set the vehicle-specific ID to identify videos from this particular vehicle. 

(J) On the Network page, match the SSID with the unit ID, and change the password as required. Hit the apply button, then reboot the DVR.  Rebooting DVR is easily achieved by navigating to the System Info page and hitting the Reboot key. If connected by Wi-Fi, you will be disconnected at this point. 

7. Reconnect to the LE DVR. You will connect to DVR under the new SSID alias and new password. 

8. Review all program settings to verify their correctness per Form C/customer specifications, unit ID, triggers, date & time, etc. 

9. Test the operation of all triggers. 

(A) Make and keep test videos of all cameras/triggers to show that they operate correctly. Recorded Alarm videos should show the correct unit ID, date & time, and the specific active trigger label. If the vehicle can acquire a GPS signal at your location, you should see the GPS coordinates and a location spot for vehicle speed set to record as MPH. During the trigger tests, the on-screen display should reflect “LTS” for the warning light trigger, “MIC” if the system is using the wireless mic pack, and “RDA” if the system has been enabled to remotely activate the customer’s BC4 Body Cams. 

(B) It is recommended that while you are performing the trigger tests, you should verbally state the customer/department name, the specific unit number, the current date and time, and which trigger you are testing. You should do this with each camera in the vehicle. Playing back the alarm test videos will prove proper audio operation and verify which unit you are testing. 

(C) If the squad is to be equipped with the wireless mic pack, test as follows: Turn on the main power switch on the bottom of the wireless mic pack and place it in the charging cradle. When the DVR system is powered on, and the mic pack is first placed in the charger, the LED on the top of the unit will blink rapidly for several seconds, showing that it is syncing with the DVR system. Once the unit stops flashing, it is synced. Take the mic pack out of the cradle and activate the Talk button on top of it. The red LED should turn on, and the mic pack trigger should be active. Walk around the vehicle to show the operational functions of the cameras designated to record Alarm video while this trigger is active. Be aware that if the system is equipped with the wireless mic feature, the audio picked up by the mic pack is the camera's #1 audio. No audio will record for camera #1 if the mic pack is not activated or if it is left in the charger.

(D) Test the warning light trigger: Activate the vehicle’s warning light system and confirm that the “LTS” trigger remains active through all the active levels of the switchbox. Besides the “LTS” marker on the video, you should also see the “RDA” indicator while the warning light trigger is active if you have set the system up to remotely activate their BC4 Body Cams. If the system has the wireless mic pack installed, activating the warning lights trigger should automatically turn on the mic pack. This should be reflected on the screen by the marker “MIC.” When you turn off the warning light trigger, the wireless mic pack should also turn off. 

(E) Test the EVT trigger: How the EVT has been programmed will determine how it will act. 

(E1) Programmed as an Event Marker. When pressed once, the DVR will record the Alarm videos the combined length of the programmed pre-event, and the post-event times. 

(E2) Programmed as a Recording Control. When no other triggers are active, the green LED on the EVT should be flashing. Pressing the EVT once should start recording the designated camera, usually the prisoner compartment camera, and the LED should turn on solid green. Stop recording by pressing the EVT a second time.

(E3) THIS WILL NOT BE AN ALARM VIDEO RECORDING. This will only be a regular video. This configuration of the EVT will allow the DVR to only record Alarm/Event trigger videos or regular video only when the EVT is activated (solid green LED).

(E4) Programmed as an Alarm Recording Control. The DVR will record regular video as programmed (green LED on solid) and switch to the Alarm recording mode of the selected cameras on the first press of the EVT switch. If programmed this way, an audible beep will be heard on the first press of the EVT. The EVT must be pressed a second time to stop the Alarm recording. At present, there is no audible deactivation verification of the Alarm video. The Alarm video will stop after the post-event time has been reached. 

10. Review all test videos. 

(A) Pull the DVR’s SD card and verify that the videos display the correct ID, date & time, active triggers, etc. Verify that cameras have audio enabled per programming. Troubleshoot any programming or hardware issues detected and resolve them. Redo the test videos after correcting the issue to confirm the correct operation. 

(B) Reformat the SD card and reinsert it into the DVR. 

(C) If the system is to include a solid state drive, SSD, now is the time to install and secure it. Navigate to the View Files page on the top bar of the program. Verify that the DVR sees the SSD and is now recording video.

(D) Try to leave the SSD installation until after completing all programming and trigger testing. Accessing your test videos is much easier from the SD card than the SSD since it requires a special adaptor cable to connect to your PC.

11. Set up the Network connection, if possible. 

(A) The customer must provide you with the name of their network (SSID), the password to access the SSID, and the URL needed to finalize connection to SecuraMax/Wireless File Transfer.

(B) You must be in an area with an access point that can physically connect to the network with at least 65% signal strength. The customer must already have the Pro-Vision program enabled for you to connect to it as well. 

(C) If the above criteria are met, you will navigate to the Network page under settings. At this point, you must be physically connected to the DVR with a LAN cable. 

(D) On the Network page, change Wi-Fi mode from Access Point to Client mode. 

(E) The DVR should begin scanning for active Wi-Fi networks. 

(F) When the DVR locates the correct SSID, select it, and enter the password. You must hit the Apply button at the bottom of the page to Save the settings.

(G) Wait 60 seconds, then switch to the System Info page and reboot the DVR. (Remember that the ignition must stay on at this point for the DVR to reboot properly.) 

(H) Depending on the customer’s network, you may be required to reboot the DVR a few times before it fully connects to the chosen network. The SSID will be highlighted in green and display “connected.” 

(I) Once the DVR is connected to the network, go to the File Transfer page, and enter the URL. If the customer system is set up correctly for auto-accept, the DVR should send and receive a unique confirmation code. Once accepted, the DVR will display “Complete” on the File Transfer page. 

12. The installation is now complete.


1. The LAN cable you installed in the vehicle will be used for connecting the DVR to the in-car PC with the PVSync program if this is what the customer wants. Connect both ends of the LAN, one end to the DVR and the other to the customer laptop/docking station, if possible. (Some computer systems may not have an open LAN port. Advise the customer if this is the case.) At this point, advise the customer that they will need their in-house IT person to set up their PC to connect to the DVR via a static IP. It is recommended to contact Pro-Vision Tech Support if they need assistance.

2. Go over the completed installation with the customer.

(A) On the first vehicle, verify with the customer the equipment locations used and the programming you performed to meet the department’s expectations. Show the videos you took to confirm they are the desired camera views.
(B) Ensure they fully understand how all the triggers will work for recording video. Make sure they understand and are satisfied with how the EVT is programmed.
(C) Provide them with the basics of extracting video directly from the SD card without corrupting video files. Basics: If the system is on and the green LED on the front of the DVR (or EVT) is on steady, they must hit the stop button next to the SD card slot until the LED flashes. It is then safe to remove the SD card from the DVR. Videos are best viewed on the Pro-Vision Player program or VLC media. The default media players found on most newer Windows computers are not recommended due to playback issues. 
(D) After completing all vehicles, provide the customer with all spare parts, documentation, and keys. Have any necessary final paperwork signed by the customer at this time. 

3. Leave your work area as clean as you find it. Dispose of garbage as directed by the customer, bagged or in a dumpster. Remember that cardboard packaging can be recycled if the customer is set up for this.
