IMPORTANT INFORMATION ABOUT MICRO SD CARDS

• The device comes with a 128G Micro SD card. Please format the Micro SD card before using it for the first time.
• To use a TF card, ensure that it is formatted with FAT32, has a storage capacity between 16GB and 256GB, and has a reading and writing speed no lower than U3. Please format the TF card before using it for the first time.
• Please regularly move your data from the Micro SD card to an external drive to avoid overloading the disk. We recommend reformatting the Micro SD card in this way at least once a month.

PRODUCT INTRODUCTION

The NexiGo D621 is a three-channel dash cam that uses G-sensor technology to detect and save footage in case of a collision or break-in. This footage can then be accessed wirelessly through the NexiGo Dash Cam app.
This dash cam features three different cameras to capture vital footage from every angle. No matter the time of day, the interior wide-angle camera is adaptable to your space with its infrared LEDs and 180° vertical rotation. Meanwhile, the front and rear cameras capture 2K and 1080p quality footage with their advanced sensors.

INSTALLATION GUIDE

• Before installing, test the device to ensure each component works as intended.
• Installation may require professional assistance. If you are not comfortable completing any of the steps listed, please contact a local professional for assistance.

INSTALLING THE FRONT CAMERA

The device comes with a 128G Micro SD card. Please format the Micro SD card before you use it for the first time.
Step 1: Assemble the suction cup mount
Slide the suction cup mount into the slot on the top of the dash cam.

Step 2: Clean the windshield
Clean the windshield thoroughly with water or alcohol, then wipe it dry with the included cleaning cloth.
Remove any protective film from the windshield before mounting the dashcam to ensure a secure installation.
Step 3: Mount the dash cam
Loosen the suction cup mount lock, and remove the protective film on the suction cup.

Firmly press the suction cup mount onto the windshield, then raise the locking lever to secure it into place.

Step 4: Route the power cable
Plug the power cable into the USB-C port on the side of the suction cup mount. Then, run the power cable along the following route:

1. Along the top of the windshield, towards the passenger side;
2. Down the A Pillar;
3.  Underneath the passenger dash panel; and
4. Into the auxiliary power outlet.

Optionally, you can hide the cable by using the pry tool to pry back the edges of the trim enough to tuck the cable underneath. If you choose not to hide the cable underneath your trim, you will need to tape or clip the cable into place.

• Ensure that the placement of the power cable does not interfere with your vision or impede your ability to drive in any way. If you are not sure if you can do this without risking the safety features of the vehicle, please contact a local professional for installation assistance.
• It is important to ensure that the placement of the cable doesn’t interfere with the vehicle’s airbags or other safety functions. Failure to properly run the wiring may be a violation of local regulations and can result in fines or serious injury.
• Consider using a hardwire kit instead of the provided auxiliary power cable if your auxiliary power outlet supplies a constant power source. This will prevent the dashcam from draining your car battery, as the constant auxiliary power outlet will constantly power the dashcam.

INSTALLING THE REAR CAMERA

The following steps detail how to mount the rear camera above the rear license plate. While we recommend this location because it works for most passenger vehicles, it doesn’t work for everyone. Please consult a professional to decide on an alternate solution if this placement doesn’t work for you.

Step 1: Apply tape to the mounting bracket
Remove the adhesive backing from one side of the double-sided tape. Adhere the double-sided tape to the mounting bracket of the rear dash cam as shown in the image below.

Step 2: Mount the rear dash cam
Thoroughly clean and dry the mounting surface above the license plate. Then, remove the adhesive backing from the other side of the double-sided tape, ensure the camera lens is pointed outwards, and firmly press the camera onto the mounting surface.  Alternatively, you can screw the rear camera into place using the included mounting hardware.

Ensure that you are not blocking any sensors, latches, buttons, or any other items needed for vehicle operation. Please ensure that your license plate is fully visible.
Step 3: Remove your trunk’s interior panel
Open your trunk. Using the provided pry tool, remove the interior trunk panel as shown in the image below. Removing this panel will expose one of the vehicle’s rear wiring bays so that the wiring for the rear camera can be run cleanly.

Step 4: Conceal the rear camera cable within the trunk of your vehicle
Use the pry tool to remove the tailgate trim as shown below. Then, insert the rear camera cable into the trunk of the vehicle through the holes that were underneath the trim.

Step 5: Route the rear camera cable
Route the rear camera cable to the front of the vehicle as shown below.

Replace the trim panel once you finish running the cable. Optionally, you can hide the cable by using the pry tool to pry back the edges of the trim enough to tuck the cable underneath. If you choose not to hide the cable underneath your trim, you will need to tape or clip the cable into place.
Step 6: Power and test your dash cam
Connect the rear camera power connector on the auxiliary power cable to the rear camera extension cable as shown below.

Then, start your car and turn on the dash cam. Test the device to ensure that it is functioning properly and that there are no issues with the wiring.
Step 7: Secure the angle of the rear camera
Test your rear camera to find the best angle, then tighten the hinge screw to secure the unit in place, as shown in the figure below.

MENU WALKTHROUGH

The D621 Dash Cam menu is divided into categories for Camera Settings, System Settings, and Wi-Fi Settings. In the menu, you will also find a Format SD Card tab and an About tab. The following pages contain an overview of the functions available in each category.

CAMERA SETTINGS

Resolution| Adjust the resolution of the front camera. Choose between 1440p@25fps and 1080p@25fps.
---|---
Loop Recording| Opt into recording footage from your trip in small segments rather than one continuous video. Choose between 1, 3, or 5 minute segments.
Loop Recording| When Loop Recording is enabled, the dash cam will automatically erase the oldest files to make room for new footage when the Micro SD card is full.
Video Encoding| Choose between H.264 and H.265.
Anti-Flicker Mode| Toggle between 50Hz and 60Hz power line frequency.
Audio Recording| Enable/Disable audio recording.
G-Sensor Sensitivity| Adjust the sensitivity of the G-Sensor. Choose between Low, Medium, High, and Off.
• The G-Sensor is the component that detects collision by sensing sudden changes in speed and momentum. When this happens, the dash cam will automatically save the footage surrounding the incident to a locked video directory. We highly recommend backing up this footage on an external drive as soon as possible to prevent it from being overwritten.
•   When driving, if the road is bumpy such as on gravel or dirt, please adjust the sensitivity to Low to prevent accidental emergency
recordings. When parking, we recommend adjusting the sensitivity to Medium.
• The dash cam may not save every emergency video under the locked video directory. If you are unable to locate an emergency video under the locked video directory, please check under the normal directory.

FAQ

Q: How do I format the Micro SD card?

A: To format your Micro SD card using the dash cam, open the menu of NexiGo dash cam and navigate to Settings > Format SD Card. If you are using a computer or laptop, follow the instructions provided by the operating system manufacturer to format a disk.

Q: Why won’t my dash cam turn on?

A: Most likely, your dash cam won’t turn on because it isn’t powered properly. Please try the following to fix this issue: 1. Ensure the power cable is firmly plugged into the USB-C port on the dash cam. 2. Check your vehicle's auxiliary power outlet for debris, corrosion, and other damage. If needed, clean it out or try a different outlet. 3. Ensure the power cable is firmly and fully seated in the auxiliary power outlet. 4. Check to make sure the car fuse for the auxiliary power outlet hasn’t been tripped. 5. If your dash cam still won’t turn on, please contact our support team at cs@nexigo.com.

A: There may be an issue with your Micro SD card. Please try the following to determine the source of the issue: 1. Ensure that your Micro SD card is fully inserted into the device. 2. Format the Micro SD card using your PC and then try using it with your dash cam again. 3. Try using another Micro SD card. 4. If you are still receiving the error message after trading out Micro SD cards, please contact our support team at cs@nexigo.com.

Q: Why are all of the recorded videos blurry?

A: There may be something on the lens preventing your camera from recording clearly. Please try the following: 1. Check both the front and rear camera lenses for debris and other smudges. If necessary, clean the lenses with a microfiber cloth and a lens cleaning fluid. 2. Ensure that the protective film has been removed from every lens. 3. Clean the windshield near each camera, both inside and outside of the vehicle.

Q: What is the Wi-Fi range?

A: The Wi-Fi signal range is about 10 ft when there are no obstructions.

Q: Can I change the Wi-Fi password?

A: Yes. You can change the Wi-Fi password in the NexiGo Dash Cam app by navigating to Live View > Dash Cam Settings > Wi-Fi Connection Settings. After changing the password, please restart the dash cam. You must forget the original network on your smartphone before reconnecting.

Q: How do I record clear footage at night?

A: If your dash cam isn’t capturing enough detail at night, you can adjust the Special Exposure Level to compensate for the low light. To get the most out of this setting, we recommend taking the following steps to correct your dash cam’s night vision. 1. Park so that you’re facing another car and turn on your headlights. The reflective surface of the other car’s license plate will serve as a reference point when you adjust the exposure settings of your dash cam. 2. Press and hold the OK button for entering the Set the Exposure Level (or navigate to Settings > Camera Settings > Set the Exposure Level) to adjust the exposure of the front-facing camera until you can clearly see the license plate of the vehicle ahead. 3. To avoid changing the Special Exposure Level each time you want to enable or disable this feature, adjust the time range for when these exposure changes are active using Set Special Exposure Time in the Camera Settings menu. 4. Rotate the interior camera until it faces forward, and flip the camera view under Settings > Camera Settings > Interior Camera Position so that the footage is right side up. The brighter, infrared- enhanced footage of the interior camera will capture all the detail that the front camera cannot. Now you can record normal front view footage plus license plate monitoring footage at the same time.

Q: What should I do if my latest videos are being overwritten?

A: Your Micro SD card is full. We encourage you to do the following to prevent any more data loss: Move the old files off your Micro SD card regularly. Format the Micro SD card once a month to keep the device running normally. Replace the Micro SD card with a new Micro SD card once a year.

Q: How do I transfer files from the dash cam to my computer?

A: Turn off the dash cam and remove the Micro SD card from the device. Using a card reader, insert the Micro SD card into your computer. You can then drag and drop files from the Micro SD card onto your computer. Do not insert or remove the Micro SD card while it is saving or reading data. The data may be damaged or lost. Only insert or remove the Micro SD card when the dash cam is turned off.
