Rexing V5 Dash Cam Review – First Ever Modular Design

The Rexing V5 dash camera is a high-end dash cam with a twist.

It has all the features that you’d normally expect from a good quality dash cam except it can be easily upgraded with optional add-on cameras.

Currently available is:

• A rear view camera
• A waterproof outside-mounted camera
• An internal cabin view camera

These add-ons are easy to install and can significantly improve your dash cam’s functionality.

In this review we’ll cover all of the V5 dash cam premium 4k features it offers.

What’s in the Box

• 1 x Rexing V5 4k Dash Cam
• 1 x 12v Power Cable (Cigarette Lighter Adapter)
• 1 x Mini USB Cable for Data Transfer
• 2 x Mounting Brackets
• 2 x 3M Adhesive Pads
• 6 x 3M Adhesive Cable Clips
• 1 x Panel Removal Tool
• 1 x Quick Start Guide
• 1 x 18 Month Warranty Card

Modularity and Installation

The premium 4k modular capabilities are what separate the Rexing V5 from its rivals. You no longer need to spend $300+ all at once for a top of the line dash cam. The add-on cameras (available separately) are all plug and play, so you don’t have to waste any time installing them.

Easy Installation

Installing the primary unit is simple with the included 12v power cable. You’ll need to mount the front-facing dash cam on the windshield using a 3M adhesive pad. You can adjust the wide angle lens to get the perfect angle once installation is complete.

Once you’ve done this, simply run the cable from your cigarette lighter to the micro USB port on the side of your front dash cam.

Advanced Installation

If you want to take advantage of the Parking Monitor which is a Rexing V5 dash cam premium offering, you’ll need to install the hard-wiring kit which is available separately.

The hard-wiring kit has a micro USB termination at one end. The other end has three wires; yellow, red and black. These are plugged into your vehicle’s fuse board.

On the fuse board you’ll need to identify a constant power outlet, a switched power outlet and and a nearby grounding point. The wiring goes as follows:

• Red – Constant 12v Power
• Yellow – Switched 12v Power
• Black – Ground

This wiring will ensure your Rexing V5 dash cam is powered properly and you can make use of the Rexing V5’s parking monitor.

Modular Unit Installation

Installing the modular units is simple. They all draw their power from the front facing camera.

For the rear cameras (both internal and external modules) you’ll need to run a single cable. One end of the cable goes into the rear camera, the other into the front camera. All ports are labelled clearly.

The interior cab/night vision camera has a micro USB plug built into the casing. Simply plug this into the micro USB port on the right hand side of the main unit. No other installation is necessary.

Image Quality

This Rexing camera is the V5 dash cam premium 4k model. It uses a Sony IMX335 image sensor which is great for low light and night vision. The front camera provides 4k Ultra HD 30 FPS footage if used on its own.

However, using additional camera modules means that the frame rate on the main camera drops to 24 FPS. The resolution will remain unaffected though.

The maximum resolution of the other camera modules is limited to full HD 1080p. This isn’t as high as some other dash cam’s offer but it’s sufficient for capturing details such as license plates.

There are several video settings that can be adjusted to suit your preference. The WDR (Wide Dynamic Range) setting improves detail in both daylight and night vision. Several users report that they leave this setting ‘On’ all the time.

You can also adjust the exposure to lighten or darken your image, however the default setting is fine for most lighting conditions.

The front camera also has an adjustable ultra wide angle lens to capture everything needed.

A good example of the quality you can expect can be found here.

Internal Camera

The internal cab view camera uses IR (Infrared) light to film in night vision. The IR lights can be set to come on automatically (there is a sensor on the front of the camera) or switched on manually. This setting is available from the camera’s menu.

The footage that the internal camera provides is crisp but (as with all night vision footage) greyscale. The night vision mode doesn’t impede the camera’s usefulness. Everything is visible, day and night.

Built-in WiFi

The menu on the Rexing V5 is easy to use but the ‘Rexing Connect’ mobile app is even easier.

To use the mobile app connect to the cameras WiFi network on your phone. Once you’ve opened the app, you’ll be able to access features like:

• Live View
• Change to different camera feed
• Take photos
• Change settings (WiFi, G Sensor, Resolution Etc.)
• View and download video files from the camera

It’s worth noting that not every feature is accessible from the app menu. But the main features are all there and can be easily adjusted. This is particularly useful with video settings as you’re able to see the changes take place on your larger phone screen.

Built-in GPS

Previous dash cam models have required an additional hardware GPS logger, but it’s a built-in feature on the new V5 dash cam premium offering.

A GPS Logger means that your dash cam will connect a video file to the GPS data it gathered at the time of recording. This is a security feature that allows you to prove where a piece of footage was taken.

Using the software available from the Rexing website, you can see your location overlaid on a Google maps interface. It’s simple to use and a very useful feature to have included at this price.

Standard Features

The Rexing V5 includes all of the features you’d expect at this price point. Since it’s a new model there is room for minor improvement. These improvements normally arrive in the form of firmware updates once the manufacturers have fixed any bugs.

G Sensor

The G sensor which detects collisions is reliable. When it detects a collision it ‘locks’ the current video file, meaning it can’t be deleted. Users report that the ‘medium’ G sensor setting is best to avoid false positives (resulting in locked files every time you hit a pothole).

Parking Monitor

The parking monitor which uses the G sensor is equally reliable. Once the G sensor detects an impact while in parking monitor mode, it takes between 7-10 seconds for the camera to start filming. Once it does, it records for 20 seconds.

At the moment, there is no other parking mode available. It would be nice to see a time lapse feature introduced that could provide round-the-clock recording. The G sensor trigger mode is fine but if an incident occurs quickly, you could miss important information.

Warning Systems

There are two warning systems that come with the V5. These are the Lane Departure Warning System (LDWS) and Forward Collision Warning System (FCWS).

The LDWS will alert you if you drift out of your lane, the FCWS when you’re too close to the vehicle in front of you. If anything triggers these features, the front unit will beep at you until the situation is rectified.

Some users have reported that these systems are too sensitive when driving in heavy traffic or on the freeway. They’ll be triggered too easily and the alerts can get annoying. The sensitivity can’t be adjusted so the only option is off or on.

Loop Recording

The Rexing V5 dash camera uses loop recording for efficiency. Loop recording is when new footage overwrites the oldest footage on a memory card when the storage limit is reached.

Footage is broken up into 2 or 3 minute files to save space on your SD Card.

Is it worth it?

This Rexing V5 dash cam offers something that other dash cams don’t. With the V5 you can add to your car surveillance system gradually, without needing to spend too much money at once. A different dash cam that features 30FPS UHD, WiFi, GPS and all the other features the Rexing V5 dash cam has, would normally cost a lot more.

If you’re a first time dash cam buyer, this price tag won’t discourage you. You’re getting good video quality for a good price. If you decide that you enjoy the benefits of owning a dash cam, you can easily add to your system and improve your setup. A dash cam premium 4k setup might feel excessive but it also means you won’t have to upgrade any time soon.

If you drive commercially (i.e. Uber, Lyft, delivery driver) this is also a great choice of dash cam. The modular system provides unmatched flexibility and gives the user complete control over their car camera system. The cab view module is particularly useful for taxi drivers.

So whether you’re a commuter, you drive with your family or you drive for a living, the Rexing V5 dash camera is definitely worth it. For the price you won’t find another car camera system that’s this easy to use.
