What’s in the box?

The box contains the camera, a battery, a cable and instructions.

A Closer Look

There is also an app you can install onto your smartphone.

You can see, and control all of the device settings from the app.

Final Thoughts

The first thing you notice when you open the box is that the camera is very very small so it can easily slip in to a pocket or bag and not take up much room at all!

Setting up the camera for the first time was very simple and quick – using the app made it even easier as the touchscreen on the back of the camera is quite small.

You connect the app to the camera using the cameras built in 2.4Ghz wifi and then you use the app to download any firmware updates and then send those to the camera.

You can change a number of settings, including the quality of the recordings (all the way up to 4K 20fps), the format of the records (NTSC or PAL), sounds, and so on. You can also see various information such as the size of the card in the camera, record times, and so on.

Using the camera is so easy – just press and hold the power button on the top of the camera to switch on, then press the same button to start and stop the recording. My only slight gripe with that is that the button is fairly sensitive so it is easy to stop the recording by accident – although this will largely depend on how you hold the camera.

There are different modes built into the camera, including burst mode and time lapse mode so it’s a lot more than just a simple point and shoot.

The battery life is very good – you get around 75 minutes of recording at 4K and around 110 minutes at 1080p. The battery is charged via the supplied cable when you connect it to any USB port or plug.

You can also take pictures with the camera if you didn’t want to shoot video.

You can use the app to view live video if you wish so you could set the camera up somewhere and then control it from the app. You can also use the app to edit the pictures and video and then share whatever you produce easily.

The sound quality is very good too.

There is also a waterproof case for the camera which we will look at separately.

The YI Discovery Action Camera is a great addition to whatever your existing camera set up is – YI describe it as a backup camera but you can certainly use it for more than that if you wish, and for the price its a no brainer – buy it today, you really wont be disappointed.

The YI Discovery Action Camera is available now priced around £42.99.

You can learn more from the Yi website.
