Check out reviews on Youtube on Vortex radar, Blackboxmycar and Safe drive solutions. They give detailed reviews with footage samples

Viofo has something with the starvis 2 sensor in India as well but its a 4k + 1080 unit https://viofo.in/product/viofo-a139-...imx678-sensor/

But its only the front which is starvis 2. Rear is starvis 1.

Was also just informed by Viofo that the 229 is launching here in 25 days. 229 is starvis 2 all around and comes with a screen to view footage without the app/phone thing.

I got this Viofo A139 Pro dual channel dashcam recently and I have shared my initial experience along with sample footage. Post (The Dashcam / Car Video Recorder (DVR) Thread)

Like you mentioned, front camera has Starvis 2 sensor and does 4K recording. Rear can record only 1080P, in this dashcam.

Superb. Just read your user review. I watched both videos. Front is crystal clear. But the rear looks boggy. I tried to see if I could read the number plates on the rear but I wasnt able to on my phone. Is it visible on your laptop?

That said, would a starvis 2 based rear cam on 1080p provide better visibility both at night and day than the starvis 1 based 1080 that comes on the 139? Wonder if there are any YouTube videos comparing the both.

Hi..

Noob question.. But question nonetheless.. and lots are 70mai dashcam owners, so does the ADAS work well? Is it really useful? Does one prioritise this feature to buy a 70mai or should one stick to (the generally much more expensive) Viofo? Any feedback/opinions between 70mai A810 vs Viofo A129 Pro Duo ultra?

Thank you soo much!!

Vikram

I had a 70mai dash cam with ADAS feature. Let me tell you that it is purely a gimmick. It works so slow that a vehicle will pass you closely, you will see it react to it and after the vehicle is clear the camera will warn you about it. It works better when stationary for when a vehicle in front starts moving and it gives you an audible warning that the vehicle in front is moving otherwise in a moving vehicle it is too slow to be useful.

How important is a super capacitor? Looks like none of the 70mai cameras have this?

Generally the units offering rear cams do have the cable lengths sufficient enough for an SUV.

Thanks. I have ordered the Z40 finally. Will post again with my installation experience in a few days.

Would that not drain the car battery fully since this dashcam model most likely does not support a parking mode with power connected?
Also, in my specific case, the car is parked in a closed compound, so parking monitoring isn't a strong requirement most of the time. I understand that parked on the street, I am vulnerable.
I do intend to change the battery inside the dashcam eventually. I am just being lazy there.

The ADAS feature is a joke atleast on my 70MAI Pro. The only time it may help is when you are distracted looking at your phone on a traffic sign and the vehicle ahead of you moves when the traffic sign turns green. But again, the vehicle behind you will alert you anyway if you are in India.
The lane departure warning doesn't always work and the "beware of the vehicle ahead" warning will be heard after the crash if you don't break looking at the vehicle yourself.
I would not bother about the ADAS features in a dashcam. Not connected to the car (engine/breaks), it does not add much value.


Thanks,

The biggest advantage of Capacitor based dashcams as they are said is their ability to operate in extreme weather conditions i.e high temperatures which the Li-on battery dashcam supposedly cannot operate. Other than that capacitor dashcams don't offer any significant feature which Li-on battery operated provide.

If living in metros or Tier 2/3 cities where the operating temperature are within the design temp of battery operated dashcams, its fair to use them. Plus they are quite low priced when compared to capacitor based dashcams. 70mai dashcams are no different in this.

I had Yi dashcam in my previous car and it worked well being a battery operated unit.

Hi All, I have finally ordered one ROVE R3 from US for $199 while same was at Amazon US approx ~ $300.
Key features: ROVE R3, 3 Channel Touch Screen Dash Cam with Built-in Dual-Band 5GHz WiFi, Built-in GPS, 24 Hr Parking Monitor, Super Capacitor, WDR, G-Sensor, Night Vision.

What I feel now, all the dash cam are more or less and rebadging being done.

The local VW dealer in Pune is offering the DHC C01 dashcam ( front and rear) for Around Rs 17.5k including fitting.

Tried to find reviews about this product but not much luck. Also their website does not say if the product has Li-ion or capacitor type batteries. Anyone heard about this brand?

For Viofo A139 Pro 2CH Dashcam, the rear camera comes with 6M cable. It was more than sufficient for installation. I had to even fold a good extra length of cable to be hidden away. Cable routing was done on the top side of the car, in my case (Fortuner).

Watching from laptop, I can see the number plates at 2-3 places only during that video I shared from my rear camera. Number plate reading isn't easy from this rear camera, due to sensor, and having lower resolution.

What I read about Starvis 2 sensor it is highlighted as ' better low light sensor', so night vision is expected be better with that sensor. And there are some Viofo models A119 Mini, that has Starvis 2 sensor, offering 2K resolutions, do check them out. https://viofo.in/product/viofo-a119-...ge-sensor-hdr/

My previous Dashcam was having Li batteries, I used 2 of them for 8+ years without issues. However the environment we are using if its extreme temperatures, then better to stay away from batteries. Also batteries can fail, expand and damage the cameras in those cases.

Check with contact number mentioned on their site to confirm. On Amazon, the camera specifications says Battery Required as No. it must be capacitor based I assume.

Thank you for writing back. One more follow on. Between a 4k resolution and starvis 1 and a 2k res and starvis 2, which combo would you pick?

[vvrchandra]

Viofo A139 Pro comes with 2 electrostatic stickers. Can we use one of the sticker on the rear windshield which has defogger lines. Is it safe to use the sticker on rear windshield. Thanks.

Any feedback/opinions between 70mai A810 vs Viofo A129 Pro Duo ultra? Is the Viofo worth the extra bucks?

Using the 70mai dash cam or a month now. there are 3 main "ADAS" features:
1. Lane departure (works ok on highways)
2. Vehicle ahead motion (useful but can get annoying in traffic)
3. Vehicle ahead detection (too slow to be useful)

You can surely live without these features. M300 + rear cam will do most of the job.
