Back up recordings before changing settings
On a computer, open BlackVue Viewer and select Settings to change firmware settings. Use the manual for your camera's firmware if an option looks different. Check a saved front and rear clip after making changes.
DR770X-2CH sample footage
Video quality, sound and GPS
The original DR770X-2CH records 1080P FHD at 60 FPS from the front and 1080P FHD at 30 FPS from the rear. Resolution and frame rate are fixed, and each video segment is one minute. Frame rate can vary during Wi-Fi streaming. Older playback devices may also struggle with 60 FPS footage. The original manual lists STARVIS CMOS sensors for both cameras.
We suggest High as a starting point for image quality. Choose a higher tier when detail matters more than retention, or a lower tier when card space matters more. Higher bitrates create larger files. Compare saved footage before settling on a setting. The original manual lists these front and rear bitrate pairs:
Swipe or use the Left and Right arrow keys to read the bitrate table
| Quality | Front bitrate | Rear bitrate |
|---|---|---|
| Highest (Extreme) | 25 Mbit/s | 10 Mbit/s |
| Highest | 12 Mbit/s | 10 Mbit/s |
| High | 10 Mbit/s | 8 Mbit/s |
| Normal | 8 Mbit/s | 6 Mbit/s |
Higher quality creates larger files and takes longer to load or copy. If your phone cannot stream Highest (Extreme) recordings, the manual suggests downloading the file for playback from internal memory or using Quick playback. Back up footage before saving a quality change.
Audio recording controls whether sound is included. Leave it on if you want cabin audio in your clips, or turn it off if you do not. Play a saved file to confirm your choice.
GPS location recording is a separate choice. Turning it off stops location from being recorded or sent to the Cloud and affects location-based features. The original manual says time correction, speed display and speed-related events still work. Location tracking and geofencing need location data; verify any Cloud feature you intend to use with your current service.
Rotation and video overlays
If the front camera is mounted upside down, its rotation setting turns the recorded image 180°. The rear-camera setting can rotate the image 180° or mirror it. Check a saved clip so both views match the installation.
The video-overlay switch controls whether date, time, speed and user text appear on recordings. You can turn the date/time display on or off, select km/h or MPH for speed, or turn the speed overlay off.
User text appears in the top-left corner. The original manual allows up to 20 characters, using English letters, numbers and supported symbols (: ; apostrophe / + - _ ( ) $ #). Choose text you are comfortable including in any footage you share.
Normal and parking recording
With Normal recording enabled, the camera records continuously in a loop and also creates event files. If you disable it, the camera records only event videos while in normal mode. Keep continuous recording enabled when you need footage beyond triggered events.
Parking mode needs power while the engine is off, through a supported hardwired installation or parking battery. With the hardwiring cable, ACC+ signals parking-mode entry when the vehicle is turned off. The manual also describes entry after five stationary minutes using the G-sensor with another power method; that does not make a switched-off accessory outlet supply power.
Motion & Impact detection saves a parking recording when motion is detected, with a separate event file for an impact. Adjust motion sensitivity for where you park so rain, wind or passing activity does not trigger unnecessary clips. The manual also describes selectable detection regions. Time lapse is an alternative that records one frame per second and plays back at 30 times normal speed; an impact creates a separate normal-speed event.
The rear-camera parking switch controls whether both cameras record together. If you turn rear parking recording off, the rear camera stops five minutes after entering parking mode and starts again when normal mode resumes. Check this setting if rear coverage is important to you.
Battery protection applies to the hardwiring power-cable installation. The camera shuts down according to the cutoff voltage and timer you select. Choose these for the vehicle, battery condition and parking period with your installer; no setting guarantees unlimited parking time or prevents every battery problem.
Time, lights and camera controls
Set the correct time zone for GPS time synchronization, or use manual time settings when needed. Check the recorded date and time afterward. Back up recordings first: saving time changes can format the card.
Recording-status and security lights have separate controls. You can switch the recording LED, front security light in normal mode, front security light in parking mode and rear security light on or off. These lights help you check camera status, so make sure you can still recognize the behavior you expect.
Enable the touch sensor if you want touching it to trigger manual recording.
BlackVue parking-mode video
The original control guide identifies blue as the GPS light, with quick blue flashes when GPS is turning off, orange for normal recording, red for event or manual recording and green for detected motion in parking mode. The connectivity light is yellow for LTE, white for Wi-Fi, and slowly flashes yellow when Bluetooth is paired. LTE requires the optional connectivity hardware and applicable service.
Voice guidance and its volume can be adjusted separately. Choose whether you want announcements and how loudly they play.
Scheduled Reboot lets you enable or disable a daily restart and choose its time. The camera must be in parking mode at that time; the restart is skipped if it is recording. Set a time that suits the way you use parking mode.
Firmware language changes the camera's language. Available choices depend on the firmware installed.
Format the card only after backing up footage
To use the physical format button described in the original manual, press and hold it for five seconds, release after the beep, then press and hold it for another five seconds and release after the next beep. Formatting erases recordings, including locked files. Copy anything you need to another device before starting.
Event recordings and alerts
Manual recording can be enabled or disabled. With the touch sensor enabled, touching it triggers a manual recording. Driving-impact and parking-impact settings use the G-sensor to create event files; adjust sensitivity so minor bumps do not create excessive events. Driving-impact beep alerts can be switched on or off.
Parking impact history alerts notify you when leaving parking mode if an impact was detected. The original manual says impacts in the final three minutes before leaving parking mode are ignored by this history alert. Review footage when an event matters rather than relying on the announcement alone.
Protect event files covers driving and parking impact events and manual recordings. The original manual documents a maximum of 50 locked files. Once that space is full, review and copy important footage, free space, or allow older locked files to be overwritten by new events. Formatting still deletes locked files.
Choose km/h or MPH for driving-event thresholds. Speed alerts record an event when the car exceeds your selected speed limit. Hard acceleration and hard braking use configurable acceleration or speed-reduction thresholds. Each of these triggers has a beep-alert option.
For hard cornering, the original manual describes an event when a turn of more than 60° is detected within two seconds while above the configured speed threshold. Its beep alert can also be enabled. Set thresholds for the footage you need; these alerts do not replace attentive driving.
Cloud uploads require a working internet connection and applicable BlackVue service. The optional CM100GLTE also needs compatible cellular service, and availability varies by country. Before relying on an upload, check which event types and camera channels your current camera, firmware and plan support, then confirm that the clip arrives. Local event recording and Cloud upload are separate checks.
Quick answers
Can I change the resolution or video length?
The original manual fixes front/rear recording at 1080P FHD 60/30 FPS and one-minute segments. Image quality changes bitrate and file size. Wi-Fi streaming can affect frame rate.
Does turning GPS location off disable time and speed?
The original manual says GPS time correction, speed display and speed-related events are unaffected. Location-based features change when location recording is off.
Will disabling rear parking recording stop the rear camera permanently?
No. The rear camera stops five minutes after parking-mode entry and resumes in normal mode, according to the original manual.
Are locked events safe from formatting?
No. Formatting deletes locked recordings too. Back up important files before formatting or saving time and image-quality changes.
