BlackVue Voice Call: setup and compatibility
Our guide to speaking through a compatible dash cam, checking audio and choosing the right connection
What Voice Call does
We recommend setting up and testing Voice Call while the vehicle is parked. On a compatible BlackVue Cloud setup, it lets someone using the app or supported web viewer speak with the people in the vehicle through the dash cam. The camera needs power and an internet connection, and the relevant account and service must support the feature.
We recommend testing the picture and both directions of audio before depending on the connection. If either fails, our team can help you distinguish a nearby Wi-Fi issue from a remote Cloud or call-setting problem.
Keep the driver's attention on the road. A conversation can still be distracting even when nobody holds a phone. Arrange a safe time to talk, and pull over safely before operating the app or changing settings.
Voice Call and Two-Way Voice Communication
BlackVue introduced Voice Call for selected X Plus models in August 2022. It allows a back-and-forth conversation, replacing the older walkie-talkie style Two-Way Voice Communication on compatible cameras. The older feature sends short voice messages a few seconds at a time. In BlackVue's 2022 comparison, Two-Way Voice Communication worked in the app, while Voice Call supported both the app and Cloud Web Viewer.
That distinction matters when helping an owner of an older X or S series camera. Do not expect a Voice Call control just because the camera supports Cloud access. Match the exact model and firmware first; the launch compatibility table below identifies the four series covered by the 2022 announcement.
Start and end a call in the app
For a compatible setup, begin with the camera online in your BlackVue account. The 2022 BlackVue tutorial uses this sequence:
- Open the BlackVue app, select the intended camera in your account and open Cloud Live View. The 2022 screens call the entry menu Connect to Cloud.
- Allow microphone access if you intend to speak, then select the microphone-shaped Voice Call control.
- Wait for the connection check. In those tutorial screens, the control slides and turns blue when the conversation can begin.
- Select the Voice Call control again to finish, or exit the screen.
Current screen labels can differ. Use the instructions for your installed app and camera; a local camera Wi-Fi connection alone does not establish a remote Cloud call.
Check both directions of the conversation. BlackVue's tutorial says that if the camera microphone is off, the app user can speak into the vehicle but will not hear a reply. Review the camera microphone and speaker settings while parked, set an audible speaker level and make a short test call with the other person's knowledge.
If you can hear only one side, start with microphone permission at the calling phone or browser and the camera's audio settings. These checks are more useful than assuming that a live picture proves that both audio paths work.
Android and iPhone tutorials
These BlackVue tutorials accompany the app workflow. They show the interface used when the feature launched, so they do not establish today's minimum Android or iOS version. Check the current app listing for your phone before installing or updating.
The 2022 iOS instructions also described a repeated browser microphone prompt on devices running software earlier than iOS 15. That is historical troubleshooting advice, not a recommendation to install iOS 15 today. Review the microphone permissions for the app and the calling website on your own device. If you do not intend to use Voice Call, you can decline microphone access; allow it when you want to speak.
Using a web viewer
In the original Cloud Web Viewer tutorial, open the viewer, select your camera and start its Live View. Then use the top-right Voice Call button. Grant browser microphone access only when you intend to make the call, and finish with the same button or by leaving the screen. The camera's microphone must be enabled if you want to hear the people inside.
BlackVue now also documents Voice Call in FLEETA Live View. FLEETA is a separate app and web-viewer context. For fleet use, confirm which service and account your team uses before following a tutorial. Follow the instructions and service terms for the account you actually use; do not assume that an older BlackVue Cloud tutorial, a FLEETA plan and a local Wi-Fi screen are interchangeable.
Which cameras support it?
BlackVue's August 8, 2022 firmware release added Voice Call to these series. Use this table to understand that release, then confirm the latest correct firmware and current service support for your exact camera.
| Camera series | Firmware listed at launch |
|---|---|
| DR900X Plus Series | 1.009 and later in the announcement |
| DR750X Plus Series | 1.011 and later in the announcement |
| DR750X-3CH Plus Series | 1.005 and later in the announcement |
| DR750X-2CH LTE Plus Series | 1.006 and later in the announcement |
On a small screen, swipe the table sideways if needed.
The table does not mean that those old firmware versions are the latest available, or that every newer camera, account or plan has the same features. We recommend sending us the complete model name when checking an existing system, especially where Plus, LTE and three-channel versions have similar names.
Questions about connection and audio
Why is the Voice Call control missing?
Check the complete model name, its appropriate firmware and the app or viewer you are using. Confirm that the camera is online through the intended Cloud service. The presence of local Live View or an older Two-Way Voice Communication feature does not establish Voice Call support.
Why can I speak to the vehicle but hear no reply?
BlackVue's tutorial identifies the camera microphone as one cause. Check that setting and the phone or browser microphone permission while parked, then test each direction. Avoid changing several settings at once; it makes the cause harder to identify.
Do I need to be near the car to use Voice Call?
The documented Voice Call workflow uses Cloud Live View, so the remote user does not have to be beside the camera. The camera still needs power and an internet connection, and your compatible account and service must be working. Local camera Wi-Fi access is a separate connection.
Let us help check your BlackVue setup
Tell us your full camera model, installed firmware, phone platform and whether you use BlackVue Cloud or FLEETA. If Live View works but Voice Call does not, include what you see at the microphone control and which direction of audio is missing. That gives our team a useful starting point.
For a new system, browse our BlackVue dash cams and ask us to confirm Cloud features for your exact model. We will help you match the camera, parking power and connection to how you use your vehicle.
