DuoVox Mate Pro: A fun but imperfect night vision camera

Surprising low-light power with security-camera quality.

Smartphones and cameras are better than ever for night shooting, but there are still a lot of caveats. You have to hold your phone still to get decent photos as multiple exposures are added together, and video is out of the question. However, there’s an emerging category of cameras dedicated to shooting in the dark using sensitive CMOS sensors and even infrared capability.

Some of those models are designed for commercial or military purposes, like SPi Infrared’s incredible X27 color night vision camera, but a few new models are aimed at consumers. One is the DuoVox Mate Pro, featuring a Sony STARVIS 2 CMOS surveillance camera sensor that’s supposedly a thousand times more sensitive than the latest smartphone sensors.

It promises clear colors images in extremely low light, where a smartphone or your eyes would see nothing. It also offers features like face detection, 2K video and more. It just launched on Kickstarter for $599, a fair amount of cash, so how does it work? I was able to get my hands on one to test it out.

Body and features

The camera is small and light but somehow bulky, weighing just 216 grams and measuring 4 inches wide by 2.1 inches tall. However, the lens juts out three inches, so it’s not even remotely pocketable. You wouldn’t want it in your pocket anyway, as it doesn’t come with a lens cap.

Controls are pretty simple, with a power button, shutter release and four directional buttons that activate different menu settings. You also get a microSD slot that supports up to 512GB cards, plus a USB-C port for charging, powering the camera and file transfers. Most control is done using the three-inch fixed touchscreen that’s bright enough to use in sunlight, which is nice but ironic for a night vision camera.

The settings are specific for night-type shooting, so they’re not what you’d find on a typical camera. For example, it has an instant recording video mode that starts the moment the camera is powered up, in case you see a deer and want to shoot quickly. It also uses a wayback mode that records continuously, but only keeps the footage if you hit the record button. Other video settings include a loop mode, timelapse mode and motion detection (for wildlife traps, for instance).

For photos, you get a quick capture mode that takes an image when the camera is powered on and face detection that automatically takes a photo when specific people are detected. You can also set things like screen brightness, quality and more.

The Mate Pro also has some decent wireless features. By setting it as a hotspot, you can connect your smartphone and use the accompanying Roadcam app to transfer images and control the camera remotely. I used it when I attached the camera to the hood of my car so I could trigger video recording remotely.

Image and video quality

The main attraction of this camera is the 1/1.8-inch Sony Starvis 2 CMOS sensor that’s far more sensitive than conventional sensors. It lets you shoot 3,200 x 1,800 images and 2,560 x 1,440 video at 30 fps. It’s not an infrared camera, but it can detect near-infrared light and is sensitive down to .0001 lux, equivalent to a moonless overcast night sky.

Bear in mind that the sensor is designed for security cameras, so image quality likely wasn’t Sony’s first priority. DuoVox does use AI stacking to get the best exposure and keep noise down, but it’s essentially shoehorning an industrial part into a consumer product.

The 7-element lens has a fast f/0.9 aperture and equivalent full-frame focal length of about 70mm. That’s very long, and the minimum focus distance is also very long, somewhere between 10-20 feet – so it’s not at all useful for shooting close objects. If you’re in a very low-light situation, it has a powerful built-in light with three different brightness levels.

I took the DuoVox Mate Pro out at night in a variety of situations to test it out. I had clear skies but no moon, so it was pitch black outside of any towns.

As I quickly discovered, this camera needs some light to work. When I pointed it at some trees, a field and a sky, everything was pitch black except for the sky. It could see stars and clouds, but the image was extremely grainy.

If you’re planning to use it for purposes like wildlife spotting or night photography with no sources of artificial light, as DuoVox touts on its Kickstarter page, you’ll need at least some moonlight to do so.

With a bit more light, it can produce surprisingly bright images with reasonably accurate color fidelity. One shot of a town was bright enough to clearly see the scene, but almost completely black on a smartphone. I mounted it to my car and took a ride, and everything was lit up like daytime.

Even with enough light for a scene, there are some pretty large drawbacks, though. The image is clearly boosted electronically, so the less light you have, the noisier it becomes. The grain clears up with more light, of course, but at that point you could just use your smartphone or a camera.

In addition, the focal length is impractical and the focal distance too long for indoor shooting, unless you have a large room. That issue can also make it difficult to use as a wildlife trap, as any animal approaching it would go out of focus. It’s also prone to strobing with artificial light sources, including its own light. And finally, it has no stabilization of any kind and severe rolling shutter. As such, you can’t shoot video handheld unless you have steadier hands than I do.

The DuoVox Mate pro costs $600, with the price supposedly doubling to $1,200 once the Kickstarter campaign ends. It appears to be a success so far, with around $175,000 raised. But will buyers get what they expect for their purchase?

From what I’ve seen in the Kickstarter comments and elsewhere, many probably will. And the company does have a track record, having delivered previous night vision products including the Duovox V9, V8 and S1.

However, some backers may be disappointed, because DuoVox has no video that shows the true (noisy) image quality in low light. The company’s campaign really should include more images and video samples in very low light conditions, so backers have a better idea of what to expect.

That said, there are very few devices that deliver bright, full-color images in very dim light. One of those is the $800 Sionyx Aurora, which promises color images using visible and infrared light. It doesn’t offer the same color fidelity with infrared, but that feature appears to give it superior low-light sensitivity.

You could also just use a Sony A7S-series or other low-light camera and crank up the ISO to the max, then boost the signal further in post. It wouldn’t work as well in really dark conditions, but image quality would be far better.

If you’re looking for a night vision camera for travel, security or other purposes, and image quality is secondary, it is worth taking a look. DuoVox expects to start shipping in October, but keep in mind that with Kickstarter, there are no guarantees you’ll receive the product and you may lose all your money.
