VIOFO A139 Pro - Testing / Review Info

[TonyM]

I doubt we will see that kind of night vision implemented in a dash cam any time soon,

I wonder how well these night vision cameras cope with bright lights, number plate reflections etc?

 

[Müller]

Hello TonyM.

TonyM: I wonder how well these night vision cameras cope with bright lights, number plate reflections etc?

Some `driving through the outskirts of town´-videos suggest no contrast-leveling functions at work, just focused on raw low light-power.

This is very impressive sensor technology. Like traditional night vision, it can be overwhelmed by bright light to the point of completely blowing out all detail, but unlike typical military night vision which uses opto-electronic vacuum tube image intensifiers which can be damaged in bright lighting conditions, the SIONYX OPSIN uses a solid state XQE-1350 digital sensor which can not only tolerate bright lights, it can be used during daylight hours according to the company's promotional materials. Maybe one day we will see some form of this sensor technology incorporated into dash cams?

I came across a video that demonstrated how you can adjust the EV settings and make other imaging adjustments on the fly to tone down blown out bright highlights in the OPSIN. I can't seem to locate the video I watched late last night but I'll see if I can find the link. In any case, exposure, contrast and dynamic range functions exist on the camera but they are apparently manually adjusted.

According to the Viofo web site this discount has expired.

According to the Viofo web site this discount has expired.

It was valid until 10-Mar-2023. It depends on which time zone the website is using to validate the discount code with. It's 11-Mar-2023 in China (GMT+8), but the IP address for www.viofo.com is based in Philadelphia, PA. I'll ask VIOFO if they can extend the discount code again.

 

[Dashmellow]

Pehaps the discount code has expired due to the "Spring Sale" Viofo just announced today? You can get $30 off the price of the A139 Pro rather than $20 from the discount code.

From IWA in Germany i saw some cool new dot sights, with thermal on top from holosun.
So you could use them as strait up thermal or as a 50/50 thermal and regular sight.

Instantly got thinking " i need a long gun, and one of these sights "

I'm not so sure you can do that, but more power to you if it works!

Lady at checkout saying " i have some coupons " and proceed to whip out a shoe box filled to the brim.

I am happy that are not a sale avenue that is used in Denmark, even if you can get two trolleys filled to the brim for 8 dollars.

I saw this at the shot show in the US. Holosun does some cool stuff, this included.

VIOFO has extended my discount code for $20 USD off of the purchase price of a VIOFO A139 Pro dash camera until 31-Dec-2023. I just tested the discount code and it takes an additional $20 USD off of the current $30 USD discount for their Spring Sale.

Hello, A139 Pro + HDR. RMA?

Hello, A139 Pro + HDR. RMA?

I think you have it aimed too high and its hunting for the correct exposure, aim it down so the horizon is in the middle and it'll do better.

 

[Stiv]

It didn't help

HDR off didn't change it either.

So, it's broken.

It still might be a firmware bug - Wait for the next firmware before starting an RMA. Viofo reproduced and fixed a pixelation bug I reported to them (they said it happens when going from light to dark while 2K 60 fps). I tested the beta firmware (V1.1_0314) with their fix and confirmed it solved my pixelation issue.

 

[Stiv]

Maybe yes, but so far the firmware has not solved it (i tried the last 3). And others on the Internet do not have this problem.
