VIOFO A139 Pro 1CH Front Dash Cam

The VIOFO A139 Pro 1CH records the road ahead in 4K at 30FPS from a compact, screenless camera. Its Sony STARVIS 2 sensor and front HDR help balance light and dark scenes, while the lens rotates to suit different windshield angles. Choose this package for front coverage; it includes no rear or cabin camera. Local Wi-Fi connects a nearby phone for setup and playback.

The cameras supplied in this package

The front camera has an 8MP Sony STARVIS 2 IMX678 sensor, 1/1.8-inch type, with an F1.6 lens and 140° field of view. It records 3840 × 2160 at 30FPS. No rear or cabin camera is supplied.

The optional 2K 60FPS front setting requires HDR off.

Front HDR for mixed lighting

HDR combines exposure information to balance bright headlights and darker road areas. It is a front-camera feature. Light, distance, motion and glare still affect readable detail, so inspect saved recordings under your normal driving conditions.

The front CPL-200 is included to reduce dashboard reflections. No secondary filter is needed for this front-only package.

Adjust the lens before driving

The front lens rotates through nearly 300° so you can aim it for the windshield angle. Keep the road horizon level and the view clear of mirror housings, tint edges and windshield obstructions. If you turn the lens into the cabin, it stops recording the road ahead.

Use the phone’s live view while parked to check alignment. The camera has no built-in screen. After installation, inspect original recordings to check focus, reflections and the front view.

Front coverage and saved GPS data

The 140° front lens captures the road ahead. The GPS mount records location, speed and time for compatible playback. Adjust the time zone and daylight-saving setting so recorded timestamps match your location.

For a newer front-only camera with a display and the same 4K 30FPS resolution, compare the A229 Pro 1CH. The A139 Pro remains screenless and uses its nearby-phone app for settings.

Local Wi-Fi playback and camera alerts

Use 2.4GHz or 5GHz Wi-Fi to connect a nearby phone to the VIOFO app. You can adjust settings and download recordings. Download speed depends on your phone and surroundings.

The camera speaks status notifications, including card errors and protected-file messages. It does not accept voice commands, provide LTE/cloud remote viewing or send parking push alerts while you are away. An optional BTR200 remote provides a physical control for protecting an important clip.

Parking modes need a suitable power supply

The A139 Pro supports buffered event detection, time-lapse and low-bitrate recording. Event mode saves detected activity; time-lapse records continuously at a low frame rate without audio; low-bitrate mode saves continuous video with audio.

Use a compatible HK3-C or VIOFO HK4 hardwire kit to provide constant power, an ignition signal and low-voltage cutoff. Runtime varies with the battery, cutoff, temperature and recording settings. A switched socket stops supplying power when it turns off; the camera’s supercapacitor is not an extended-recording battery.

Cable routing and storage

The supplied front camera needs its vehicle power connection. A139-family rear/interior coaxial cables are only relevant if you later add compatible hardware.

Choose a high-endurance microSD card up to 512GB. All supplied camera files share that card. Export important originals before loop recording reuses space, and back up recordings before formatting or updating firmware.

Frequently Asked Questions

What cameras are included?

This VIOFO A139 Pro 1CH package supplies one front camera. No rear or cabin camera is included.

What frame rate does this configuration record?

The front records full-height 4K at 30FPS.

Can I use 2K 60FPS with HDR?

No. The manual states that front 2K 60FPS requires HDR off; enabling HDR switches it to 30FPS. This setting trades the front’s 4K resolution for a higher 2K frame rate.

Do all cameras have STARVIS 2 and HDR?

The front uses Sony STARVIS 2 IMX678 and supports HDR. This package supplies no secondary camera.

How do I aim a camera without a screen?

Connect a nearby phone to the VIOFO app and use live view while parked. Rotate the front lens to suit the windshield, then inspect original recordings. Turning the front lens toward the cabin removes the forward road view.

Does it accept voice commands?

No. The A139 Pro gives spoken status notifications but does not respond to voice commands. Use the buttons or app; an optional BTR200 remote can protect a clip with a physical button.

What is required for parking recording?

Use a compatible HK3-C or VIOFO HK4 hardwire kit. The installation needs constant power, ignition sensing and ground. Configure the cutoff and check the transition between driving and parking. Memory card and kit are sold separately.

Which parking mode should I choose?

Choose buffered event detection for detected activity, time-lapse for a continuous low-frame-rate record without audio, or low bitrate for continuous video with audio. Storage use and useful runtime vary by mode and power supply.

Will it record overnight and notify my phone?

Overnight runtime is not guaranteed; the battery, cutoff, heat and settings determine when recording stops. The A139 Pro has no LTE/cloud remote service and does not send parking push alerts to a phone away from the vehicle.

Can I delay parking mode entry?

The manual describes immediate entry or a 90-second delay with a hardwire cable. It says this delay does not work with an external battery. A separate parking timer can limit how long the camera records.

Which card and filters fit?

Use a high-endurance microSD card up to 512GB. Front CPL-200 is included. There is no rear filter to buy for this front-only package.

Can GPS or Wi-Fi locate my car remotely?

No. GPS stores route, speed and time with recordings, while Wi-Fi connects a nearby phone for settings and downloads. Neither feature is a cellular tracker or internet connection.

Can I connect an external microphone?

Yes. The A139 Pro supports an optional compatible 3.5mm microphone. It also has a built-in microphone, and audio can be switched off in the settings.

Which firmware should I use?

Use the A139 Pro firmware page and its FWA139P.bin file. The original A139 uses a different file. Back up recordings, format the card as instructed and maintain stable power through the update. Recheck settings and sample clips afterward.

What condition is this unit in?

BlackboxMyCar Outlet products are tested, like new and backed by our in-house 10-point check. This unit includes a 12-month BlackboxMyCar warranty and our normal return policy. See our warranty and returns terms for coverage and claims.

What should I know about this package before ordering?

This package includes a 12-month warranty and front CPL-200. Memory card, hardwire kit, remote are sold separately.
