Viofo has sent over their latest A129 dual dashcam for testing.

Do note that this is a pre-production unit. So there is no retail box, accessories or manual. Production unit might be different from what I have below. Expected to launch end of May 2018.

Dual band Wi-Fi
Bluetooth remote
 GPS mount (optional)

(Getting some confirmations for the above)

Recorded in 1920×1080 30fps with an overall bit rate of 16.9 Mb/s.


Final thoughts
Well, this A129 is not yet in its final form.

What do I like about it? 1) Better mount system, slides to the right, not up. 2) Sony IMX291 Starvis sensor for both front & rear cam. 3) Dual-band WiFi. 4) Great new lens. 5) Bluetooth remote for emergency recording. 6) Removable rear cam 7) Parking Mode (hardwire kit).

I miss the power button from the A119/A119S/A119 Pro.

    Hello, thanks for this preview. You did not tell anything about parking mode. Is it pre-buffered ? Does it records 5 seconds before motion or impact ?

      Jeremy Wong · May 26, 2018 at 1:42 am

      I couldn’t test the parking mode as I don’t the hardwire kit with the A129. Also, the firmware for the A129 is not yet finalized. Will test out the parking if I can get the hardwire kit.

    Hi, can it record at 60fps for the front and at the same time record 30fps at the rear camera? …recording for front 60fps and rear 30fps or front 30fps and rear 30fps.

      Jeremy Wong · June 6, 2018 at 11:57 pm

      Hi there. It can only record in 1080p 60fps when you use the A129 as the front cam only. Dual cam can only record 1080p 30fps for both front and rear cams.

      Jeremy Wong · June 10, 2018 at 12:25 am

      Only when you use the A129 as a 1ch then it will can record in 1080p 60fps. 2ch will only be able to select 1080p 30fps for both.

    Is it okay to use the rear camera for recording the inside of the car (driver and passengers at the back) instead of recording what’s going on behind the car.

      Jeremy Wong · June 11, 2018 at 7:30 pm

      You’ll need an infrared red cam to record inside the cabin. The rear cam can’t record in the dark.

  • Kate · June 13, 2018 at 11:13 am

    Please can you tell me if there is an on-screen warning if the SD card is not installed/has failed/or the camera is not recording for any other reason.

      Jeremy Wong · June 13, 2018 at 11:26 am

      I don’t have a faulty micro SD to test with the A129.

      But there is a short message to insert a micro SD then a beeping and flashing LED when there is no micro SD card inserted.

    Thanks for your review Jeremy. I recently purchased this VIOFO A129. I find the picture is nice & crisp especially daytime (I havent tested night time) but there so many primitive menu structures & the beep sound is so loud/hard it should be at least softer beeps. I think there shouldve been at least two extra key buttons for ease of use. Also it wouldve been nice if the LED indicators were red, blue & green and an LED on the USB charger plug that comes in the box.

    I still havent figured a way to fit it so its less visible from outside. I think a right angle input at the mount might make it easier to fit closer to top edge of windscreen.

    Im still looking for the VIOFO wifi app (APK) I dont have googleplay.

    BTW In your photo whats the dashcam next to the VIOFO ?

      Hi there.

      If you have the top of the windscreen with the black tint, will be easier to hide.

      Here’s a link to download the Viofo apk file:

      That’s the Thinkware F800 Pro next to the A129.

        Ai · August 24, 2018 at 6:19 am

        Thanks so much for your reply. Thanks for the link (youve saved me so much stress) and thanks for the info on the other (F800) cam. The F800 looks quite discreet. It would be cool if VIOFO had a similar discreet design model.
        Best wishes Al

    will the CPL filter makes a different? it will be good if you can show the comparison between with CPL filter and without CPL filter.

  • Eddy · November 18, 2018 at 12:12 pm

    Not much different le.

      Jeremy Wong · November 18, 2018 at 12:15 pm

      Less reflection on the windscreen. Also will have rainbow effect like wearing polarized sunglasses.
