YDI H9R Waterproof Action Camera 4K WIFI Helmet Video Sport Cam Ultra HD 2.0 Inch Screen 170 Wide Angle Degree with 2.4G Remote Control, 2*1050 mAh Batteries, Free Dual Battery Charger in Accessories Kits (White)

I needed an action camera for insurance purposes while on my motorcycle. After trawling through a LOT of cameras, I quickly decided that there would be no need to spend a small fortune on a camera such as a GoPro, as it’s not for recording videos for the internet to enjoy. Saying this however, I wanted to make sure the camera I got was the best it could be.What you get=====Inside the box, there is the camera which is inside the waterproof housing, and a bunch of accessories, including a spare battery, a dual battery charger, a watch style remote, and a bunch of mounting accessories. Also included is an Instruction Booklet with various mounting methods, however the diagrams are fairly difficult to decipher, and it’s probably just as easy to rely on your initiative.Look=====The camera itself seems very well made, all the panels fit, and it looks very tidy. It is very light too, which is a benefit for anyone looking to attach this to their helmetVideo Quality=====The image quality is fairly good, and 2.7K 30FPS seems to be the sweet spot I have found. This camera uses the SUNPLUS 6350 chipset, which is known for not recording in true 4K, which does show. The quality is not terrible, but it is far from what true 4K is. Most people though would only want to record in 1080p 60/30FPS. This is what the camera is great at doing.Card Storage=====The camera is supposed to take up to a 32GB MicroSD card, however I have tried with a 64GB card and not had any real issues. I initially tried using a SanDisk Ultra 64 GB MicroSDXC UHS-I which worked, however I was only able to record in 1080p 30FPS as the video would be very stuttery on any other setting. I then used a SanDisk Extreme 32GB microSDHC UHS-I which allowed me to record up to 4K without stuttering at all. It is worth pointing out that both of these cards are Class 10, however the SanDisk Ultra has a low write speed, whereas the SanDisk Extreme has a higher write speed, and is designed to record up to 4K.Battery Life=====In terms of battery life, in my test I set the screen to turn off after 1 minute of inactivity, and recorded in 1080p 60FPS. The camera was running for 1h 15m before the battery went completely flat. As there is a spare battery, you can expect to get around 2h 30m before you would need to recharge both. In most cases this would be fine, but if you are going on a long journey, you may want to think about getting a few extra batteries. Charging the battery from completely flat to fully charged takes about 2 hours using the provided plug, cable and dock. This means you would not be able to charge one battery up while another is being used, as you would still have around 30 minutes of no recording.Other Features=====The addition of the Mini HDMI port and the Micro USB port on the side makes it very easy to view recorded videos, and view pictures you have taken. But is has to be said, the USB port should not be used for charging the battery, as it would take a lot longer to charge up fully. If you are also looking to transfer the files to your PC, using a USB 3.0 Card Reader would be beneficial as the transfer rate would be much better than if you are just using the Micro USB port on the side of the camera.The Wi-Fi app is also good, I had no issues getting the app setup and using it with my camera. Additionally, the remote is a nice touch, it means you can start recording when you are away from your camera. If for example you have it attached to the outside of your car (for those epic shots) but you do not want it recording all the time, you can just press the button on the remote and it will start recording for you.Conclusion=====Overall, I am happy with the camera, it is perfect for what I need it for. It all comes down to the MicroSD card you use, if you get a card designed to record 4K videos, you can't go wrong.Whether you should choose this or one of the many other similar 4K cameras, there really will be no difference in video quality, it will just be in the accessories you get.I highly recommend this.

The media could not be loaded.  I own 4 Action Cams and this one is the YDI G80 Action Camera. 4K. and is my favourite. It is also better than any of my GoPros were. (Sold all 3 of them) Much better. The Gyro works, and then mounting it on my Gimbal, means I can do an Irish Jig, and the footage is 100% steady. (BUT I am far too old to do an Irish Jig LOL) The camera has different lens length settings too. 170/140/120 are available to you. Even if you do not do any post production, this is VERY handy indeed for both stills and Videos. I shall enclose a video I did of this camera and a NON Gyro model side by side. You can see the difference quite clearly. Also a few stills I took on it. A few in Scotland at a wedding, one of the Peter Pan statue, at a place called Kirriemuir.All in all this unit get a 10 out of 10 from me.They are also very helpful by email from the factory, and always replied to any questions I had. Try getting THAT sort of after service from GoPro !The remote is like a real watch. It works on 2.4GHz and after you hit the button to get it speaking to the camera, you never need to do it again. Once only, and you can shoot your movies, take your stills and also..... switch the camera off. How cool is that. The accessory kit contains 2 battery's plus a stack of fittings.With the provided durable waterproof case, this camera can go as deep as 30 meters underwater. Use this for your water sports like swimming, surfing etc. also in rain / snow / muddy conditions etc.Although I do not use the Wi-fi, I did try it out. The WIFI Connection Functions are suitable for IOS, Android phones and tablets. This allows you to control your camera via your phone, to view pictures and videos swiftly, and transfer files onto your phone or share them on social media via the downloadable app called "CANANY".This camera has many excellent features, and my favourite of all is the built in Gyroscope Anti-shake systems. It also has a Diving Mode, a great Night Mode which works very well. A Dash Cam Mode with Loop recording. Wide Dynamic Range (WDR) again which works very well along with Motion Detection, Time-lapse, and Burst Photo.Last but not least, the Camera is equipped with the Novatek 96660 Chipset and a SONY 079 Sensor, dual screen with 2.0 inch front screen and 0.96 inch back screen. Pretty good stuff huh.This camera supports real (not electronically concocted pixels to create what looks like 4K) you get REAL 4K @ 24fps, 2.7K @ 30fps, 1080P @ 30 & 60FPS. 720P @ 60&120fps video resolution, and 16MP still image resolution.Get one. You will not be disappointed.
