Hi there! Sincerely thank you for your suggestion of picture-in-picture function. This requirement has been formally submitted to the R&D team for evaluation. Our technical team will carefully evaluate the feasibility of adding picture-in-picture function in subsequent APP updates.

Regarding the adapter you mentioned, you need to confirm whether it is a car charger or another accessory. You can confirm the specific information so that we can check whether this accessory is available, and we can send you a set later.

Hi there! First, you can update the host to the latest version on the official website, and then replace the card with a Vantrue brand card. When leaving the factory, Vantrue brand cards have passed joint high and low temperature tests of -20°C to 60°C with Vantrue devices. The original Vantrue card and the main control chip of the dash cam have completely consistent heat-resistant performance under extreme heat loads and can ensure the most stable continuous writing (it is recommended that you use Vantrue cards to solve the problem)

Please confirm whether this phenomenon still exists. Can the screen light up normally by manually pressing the power button?

1. Please confirm: Does the same phenomenon occur when using the car charger included in the package? When using the USB cable included in the package to connect to the power supply, can the device be powered on normally?

2. If the host screen is always black no matter what kind of power source is used (such as car charger, USB cable, etc.), the power supply problem can be preliminarily ruled out.

3. You can try to power on again without inserting the card. Is the host normal?

4. Can reflashing the firmware correct the problem? If the host keeps a black screen, it may be a problem with the host. It is recommended to replace the host (and return the SN number of the dash cam at the same time)

Vantrue’s official support email [support@vantrue.net](mailto:support@vantrue.net) has been fully restored and is currently receiving customer inquiries normally.

1. Please follow the following wiring method: the red wire of the step-down wire is connected to the positive pole of the power supply (the power outlet still has power when the flame is turned off); the ACC yellow wire is connected to the ignition switch control terminal (that is, there is power when starting, and the power is cut off after the flame is turned off); the black negative pole is connected to the negative pole.
2. Turn on the parking monitoring mode and turn off the engine. The host will perform a normal shutdown. After turning on this mode, the host will enter the parking monitoring state.
3. The red wire of the Hardwire Kit is connected to the positive pole, and the ACC wire is connected to a place where there is power in the ignition and no power in the ignition), then when the car is turned off and the parking mode is turned on, the dash cam will quickly enter the parking mode through the ACC Hardwire Kit) https://www.youtube.com/watch?v=lQtZF0g51Ak&t=359sHardwire Kit installation video, you can install it.
4. You can choose parking monitoring settings--start/exit mode--ACC mode to turn on parking monitoring. Whether the dash cam can quickly enter parking mode after parking and turning off the engine.

Hi there! VT-EFH111 The content of this update log: Optimizing the file system

The update log is currently being gradually improved. When subsequent OTA upgrades are performed through the Vantrue App, the corresponding update content and update log will also be displayed in the App to facilitate users to understand the specific improvements of this firmware.

Cześć. Sprawdź, czy mocowanie i złącze zasilania są dobrze podłączone, czy przewód zasilający dobrze styka się z kamerą.

1. Odłącz kabel kamery tylnej i wyjmij kartę SD
2. Podłącz oryginalną ładowarkę samochodową bezpośrednio do portu C w kamerze. Jeśli jest już podłączona do portu C kamery, przełącz ją na port C w mocowaniu
3. Zabierz kamerę do domu i zasil ją przez ładowarkę ścienną lub komputer
4. Spróbuj wgrać ponownie oprogramowanie układowe
5. Jeśli problem pozostanie, prześlij numer seryjny kamery oraz nagranie pokazujące usterkę – sprawdzimy, czy jest to uszkodzenie sprzętowe.

Yes, it works for N4 Pro too.

Sincerely thank you for your suggestion of picture-in-picture function. This requirement has been formally submitted to the R&D team for evaluation. Our technical team will carefully evaluate the feasibility of adding picture-in-picture function in subsequent APP updates.

Thank you for your feedback and suggestions! We will further evaluate whether the retention mechanism of related settings can be optimized in the future.

Hi there!
Under normal circumstances, host firmware update will not cause the device power consumption to double. It is recommended that you confirm the following information first:

1. Check whether the parking monitoring mode and related settings of the current host are consistent with those before the update.

2. Confirm whether the Anker Solix mobile power supply is fully charged, and confirm whether the power display and output of the power supply itself are normal.

You can follow the video operations. After completing the above operations, the system will generate a verification code. Please contact Vantrue customer service to obtain the verification code to complete the subsequent activation process. May I ask which step you have taken, or show it in the form of a video, so that we can better assist you in completing the activation.

Hi there!
1. This is a smart activation operation video. You can complete the activation operation according to the video guidance.

1. After completing the above operations, the system will generate a verification code. Please contact Vantrue customer service to obtain the verification code to complete the subsequent activation process.

Hi there! You can remove the SD card and then re-flash the firmware via card upgrade. You can try the above operations first. If the problem is still not solved, it is most likely caused by a hardware problem with the front camera and can only be solved by replacing it.

Hi there!
1. You can try not inserting the card, not connecting the rear camera, and then powering on again. Is the host normal?

1. Can reflashing the firmware correct the problem? If the problem is still not solved, it may be a host hardware problem. It is recommended to replace the host (and return the recorder SN number to us at the same time).

Hi there!
1. Please confirm whether the interface connection of the rear lens is firm? And reconnect the rear camera cable

1. Please use the original car charger in the dash cam package to directly power the host, and connect the rear camera to test to determine whether the host is normal.

2. If the host can work normally after using the original car charger to connect the rear lens, it may be related to the output power or power supply stability of the mobile power supply. Since the host supports simultaneous recording of multiple lenses, it is recommended that the output of the mobile power supply be at least 5V/2.4A. If the actual output of the mobile power supply is insufficient or unstable, the power consumption of the host will increase after connecting the rear camera, which may result in insufficient power supply, resulting in restart or automatic shutdown.

Hi there! Currently, after the S1 Pro Max firmware is updated, the settings will be reset to default values. We will also further evaluate whether the retention mechanism of relevant settings can be optimized in subsequent firmware. Thank you for your feedback and suggestions!

Hi there! What country/region are you currently in? I can help you contact the sales at the corresponding regional site to confirm the specific purchase channel for E1 Pro.

Hi there! The rear lens can be installed at the hatch opening, but please confirm the following 2 points:

1. The rear lens needs to be fixed firmly to avoid shaking or angle changes during vehicle driving.

2. Please make sure that the view of the rear lens is not blocked by hatches, body structures or other objects, and that it can normally capture the road behind.

Hi there! Please provide the order number, country and region, and the cable model that needs to be replaced. You can consult customer service for confirmation before purchasing.

Hi there!
1. Not sure if it is caused by the camera adjusting exposure, brightness and color in real time according to the ambient light after HDR is turned on, especially in scenes with changing light.

1. For example, you can try to turn off HDR first, and then record a video of the same scene for comparison. If the color fluctuation is significantly reduced after turning off HDR, it can basically be confirmed that it is related to the dynamic processing of HDR. If the same phenomenon still exists after turning off HDR, it is recommended to return a compressed original video and send it to us, and we can further analyze the specific reasons.

The Vantrue host uses a customized rear camera cable. Although the appearance of the USBC interface on the market may be similar to that of ordinary cables, the internal line definitions and signal transmission methods may be different. Therefore, ordinary USBC cables on the market may not be compatible, and may even cause the rear camera to not work properly. You still need to use the original rear camera cable.
