I didn't include bitrate in the above list, partly because it depends on how many channels you are using, and partly because I have been testing development firmware, and that doesn't necessarily have the final bitrates.

If you want better than this then you need to look at a headlamp upgrade rather than a dashcam upgrade!
The HDR is the best night time feature, letting you read any plate that reflects your headlights. and ghost-free multi-exposure HDR that works well and increases the dynamic range improvement to nearly 5x.ĭue to the large size of the image sensor, we have 4K resolution instead of 2K while still having the same pixel size, thus in this dashcam, there is no disadvantage of 4K in terms of night vision, and we also have the 7x sensitivity improvement due to Starvis-2! So if you are looking for the best night time dashcam, this is it, even without the HDR.7x the sensitivity (the result of which when used in a dashcam should be 1/7th the motion blur,.2.5x the dynamic range (the ability to record both dark shadows and bright highlights simultaneously),.2.25x the image area (physical size of the light collecting area for a given resolution),.2.25x the detail in terms of resolution (4K instead of 2K),.At the time of writing the firmware is still being optimised, so I can't say exactly how much better it is, but if we compare it to the standard A229, which is pretty similar to the standard A139 with both having a Sony IMX335 Starvis-1 image sensor, the advantages are roughly:

The big features of the A139 Pro are the rather large 1/1.8" Sony Starvis-2 image sensor, and the HDR feature that comes with it. Image Sensor - Sony IMX 678 1/1.8" STARVIS-2
So I'll just go over the new stuff, the exciting stuff! Same type and size of connectors, same interior and rear cameras, fully compatible with the standard model's remote cameras so no need to upgrade cabling or remote cameras, same hardwire kit, etc. There is plenty of information on the standard A139, so I won't go into detail on cases, cables, parking modes, etc., they seem to be identical other than the front image sensor. The Starvis-2 is only on the front image sensor at present, I expect the A229 Pro will be Starvis-2 all around. Unfortunately it is only FHD resolution at the rear, while the A229 has 2K at the rear, and the A229 Pro will likely bring some further advantages, but for now, I would sacrifice the 2K resolution to get the new front Sony Starvis-2 sensor. Until then, the A139 Pro 2 channel version is the one to look at. It is not ideal for making road movies due to having an extra wide front field of view, but since it is the only dashcam that currently has a Sony Starvis-2 image sensor, it is probably currently the best choice for road movies too!įor those wanting a top quality 2 channel dashcam, but wanting a more traditional A129 wedge shaped dashcam, I'm expecting a "Pro" version of the A229 at some point, but that is likely to be several months away. The A139 is designed as a taxi / Uber dashcam, with the 3rd channel covering the interior, but the Pro version is available in 1 channel, 2 channel and 3 channel versions, so you can use it for general purpose dashcam use. When you hear the voice announcement that the wifi is connected, you can press the connect camera button on the app, and it works, while with the A229, you need to wait a few seconds, not sure exactly how many, but if you press the app button too soon then it puts you in the setup for connecting the wifi! The A139 and A139 Pro just work correctly, it's obvious that the Pro is a new version of the standard 2K model, so you can expect all the standard features of the A139 to be working properly from release. I moved over to the A139 Pro from the Viofo A229, and there are a few things that work a little better on the A139, such as connecting the wifi. The standard A139 was probably the best 3 channel dashcam available, depending on requirements, but this, at the time of writing, is the best 1 channel, 2 channel, and 3 channel dashcam! Image quality being far superior to the A129 Pro and Thinkware U1000. The A139 Pro looks and behaves very similar to the standard A139, with the only real difference being the front image sensor, and some extra processing power to handle the 4K HDR video. The first of the Sony Starvis-2 dashcams, the "Pro" model of the popular Viofo A139 dashcam.
