The FIREFLY 6S 4K WiFi Sport HD DV Camera is yet another product to enter the cheap sport action camera market. How does this camera compete with Hawkeye-Firefly-6s-4K-21others (such as GoPro)? Is it worth the price? Should you buy it? All of these questions and more will be answered in this review of the Firefly 6S Sport action camera review.

The 6S action camera can capture 12 megapixels still images and videos in 4K resolution at 24fps. It can also record in slow motion (720p at 120 fps) and is 30 meters water proof. On top of that it has a built in gyro that stabilizes the video.

You can buy this action camera here for $80. But for such a low price and so many features, your probably wondering “is this camera too good to be true?” Keep reading and I’ll tell you the answer.

The Box

The Firefly 6S looked very similar to any other action camera. The packaging was good and displays all the features of the 6S on its side. There are a few glaringly obvious spelling mistakes on the box but apart from that everything was fine.url

Once you open the box you will see the action camera in its housing and a whole load of accessorys packed below it. Here is what you get:

  • 1x Firefly 6S camera
  • 1x waterproof housing
  • 1x 1600 mAh battery
  • 1x clip
  • 1x J shaped mount
  • 1x lens cap
  • 1x bracket
  • 1x usb cable
  • 1x bike/pole mount
  • 2x adhesive base (flat and curved)
  • 2x 3m adhesive tape
  • 1x wire
  • 3x plastic tie
  • 1x cleaning cloth
  • 3x bandage
  • 1x manual
  • 1x flat base mount
  • 1x adapter
  • 3x screws and adapter

Of course I will not review all of these addons. I would just like to mention that the manual was good but rather short. It doesn’t really tell you about the features of the product, rather just about how to turn it on and take a video (and a few other features and icons.) However, you will have to do some experimenting yourself to get the most out of this camera.

The camera also comes with a lens cap which is really useful for protection. The reason I’m mentioning this is that many cameras don’t come with lens caps and this results in them getting scratched and broken!

Design and Build

I personally think that the 6S action camera is better than the Xiaomi Yi, SJ4000 and Amk50os.201509161525449436

It feels high quality since it is compact and tough. The camera itself is made out of lightweight plastic with a clean and slick design. My only criticism of the design is that the USB and HDMI ports do not have a cover meaning that dust and dirt can easily get into them when the action camera is not in its housing.

However, when this thing is placed in its housing not only does it look great, it is also really tough and perfect for any adventure/drone flying.

Video Quality

You can record video in a variety of resolutions.

  • “4k” * – 24fps (2880 x 2160) – interpolated
  • 2.5k – 30fps (2540 x 1440)
  • 1080p – 30/60 fps
  • 720p – 120 fps
  • VGA 640 x 480 – 30 fps

I usually use 1080p when flying drones since it doesn’t use that much space but the video quality is still high.

This is a test video of the 6S. You can see that the video is crisp.

Recording in 1080p is great and works really well – especially if your looking to use this as a camera for some areal photography.

However, there is no sound or recording indicator so it can be rather hard to tell if you are recording or not.

However, there is a drawback…

This camera cannot record in 4K. Yep, thats right – this is not a 4K camera.

This is because the 4K resolution that the 6S produces is 2880 x 2160. However, the real 4K resolution is 3840 x 2160 meaning this is not a true 4K camera. Therefore, if your looking to shoot in 4K do not buy this camera.

I do not think that this is an ethical practice – tricking consumers into buying a product that they think is 4K but really it is not. If you wan’t to buy a 4K camera then get the Sony FDR-X1000V/W or the GoPro Hero 4 Black. These cameras however are much more expensive so properly think if you need a 4K camera. If not, then I would recommend the Firefly 6S but if so then don’t get this action camera.


I think that one of the best things with this camera is the Gyro. This has a huge impact with film and video quality. It makes the video noticeably more stable and therefore looks much more professional.

Application On A Miniquad

The drone itself is quite light coming in at 75g. However, there are cheaper action cameras out there on the market such as the SJCAM M20. However, on a miniquad, the shape is rather unstable and is hard to strap on. I managed to do it using zip ties but this was an awkward and lengthy process.

Application On An AP Drone

For aerial photography, this action camera is excellent. It is high quality and comes with numerous mounts and extras that will allow you to attach it to almost any AP drone on the market. It shoots high quality video and is considerably cheaper than popular cameras such as the GoPro. The Gyro is also useful in making the video look professional and smooth.

Conclusion – Should You Buy The Firefly 6S?

I would not recommend this as an action camera for a miniquad user since it is heavy and hard to attach to the quad. However, if your looking for a camera that can shoot video (and you don’t need 4K) for some areal photography, then this is probably the best cheap action camera on the market for that purpose. It is also great if you just wan’t to use it as an action camera (not just for drones) since it is waterproof and tough.

You can buy the Firefly 6S here for around $80.
