Rexing V1P Pro vs VIOFO A129

The Rexing V1P Pro and the VIOFO A129 are two of the more popular dash cams on the market today. Either one enables you to capture special events or unfortunate accidents while you are driving or even when your car is parked and you are away from it. In this article we will explore the benefits and pitfalls of each of them so that you will be able to make a more informed decision as to which one may be best for your driving situation.

The desire to be able to record events on video while driving is not something new. In the 1960’s police began using dash cams as part of the standard equipment in their patrol cars. And like all technological products, the price of dash cams has evolved to the point that the average citizen can now afford to install one in their own personal vehicle.

Loop recording and Auto start

Loop recording means that the camera will automatically overwrite older video files once the microSD card is full. As soon as the camera is powered on, it should begin recording. Manually having to turn your dash cam on is something you could easily forget to do.

GPS and Speed Logging

Having the ability to log the location and the speed your car was going can be vital information when the video is going to be used to prove innocence or guilt in a court case. And one of the great benefits of owning a dash cam is to protect you from fraudulent accident or injury claims.

Impact detection

Your dash cam should come equipped with a G-sensor. This sensor will activate the camera (especially when it is in parking mode) to create an Event tag,  so that when needed, you can easily find the video clip at a later date.

Supercapacitor

This is an important feature because sometimes the unit’s power cord can be accidentally disconnected in an accident. A supercapacitor will provide enough power in a case like this to allow your dash cam finish its recording the file without creating an error.

Buffered Parking Mode

This is another critical dash cam feature. Let’s face it, you are away from your car much longer than you are in it. Parking mode is designed to capture action for a few seconds before and after the dash cam senses an incident.

Event tagging

A dash cam that can “Tag” a video usually also keeps the file from being accidentally overwritten. Once “tagged” the video can be singled out later if needed.

Rexing V1P Pro Dual Dash Cam

Rexing V1P Pro

This Rexing dash cam has front and rear cameras that record in full HD at 1080p video @ 30fps, with wide 170° fields of view. It comes with built-in GPS that will mark time, date, vehicle speed, and location.

Having WI-FI will enable you to easily view recorded clips or share them with others. Another plus for the V1P Pro is that it has a supercapacitor instead of a lithium-ion battery. This makes the dash cam less susceptible to changes in temperature, hot or cold, and accidental power disruptions.

The V1P Pro offers loop recording so that it will overwrite older files. At the same time, it will “lock” any video when it detects an impact event, so that important footage will not be accidentally overwritten. Click here for our more detailed Rexing V1P Pro review.

VIOFO A129 Duo Dash Cam

VIOFO A129

Thanks to the Sony STARVIS image sensor, you will get great video recordings in all lighting conditions. Both front and rear cameras record in full HD 1080p @ 30fps. This dash cam has a 2” HD screen for instant playback and dual-band WI-FI that delivers a reliable connection for your smartphone of tablet.

Since there is no adjustment for horizontal, you need to make sure that both cameras are installed parallel to the horizon. That said, image stabilization is great even on bumpy roads. VIOFO offers an optional add-on polarizing lens that will help reduce glare, even in direct sunlight.

The A129 Duo uses a supercapacitor instead of regular batteries, but will only record for a couple of seconds if the 12-volt power fails for some reason.

Pros

  • Sony STARVIS image sensor
  • Built-in GPS
  • WI-FI connectivity
  • Infrared capability for dark recording
  • Parking mode G-Sensor

Cons

  • Lens pivots vertically but not horizontally
  • HD view screen tilted slightly away from the driver
  • Does not turn on automatically when the vehicle is started


Conclusion

These two dash cams are very similar to each other in respect to image quality. The VIOFO does a better job in lower light situations (>>>Check its pricing on Amazon). The Rexing has a wider field of view, but that comes at a slight loss of detail. Both are comparably priced and will provide you with dual cameras at a better price point that many of their higher-end competitors.
