No, we do not talk about its more direct competitors like Sony or TomTom but of a lot of manufacturers come from China that have decided to join the category with affordable models with cheap prices and where sometimes they do not have flush in copies the designs of the family Hero .
There is more and more and being so affordable is inevitable that they have managed to attract the attention of the public. Among this avalanche of cameras are some very interesting models and many others are expendable. With this shopping guide we want to help you separate the grain from the chaff because even though you have heard that it “records as well as a GoPro and is worth less than half”, do not listen it. This is all you need to know.
When we begin to see action cameras the first thing that will catch our attention will be resolution. For some time, this number does not mean much because having more pixels in the sensor does not translate into better image quality. It’s easy to find what model each carries: Sony, OmniVision, Panasonic …
Of the specifications that we can see at a glance in an action chamber there are two aspects that should interest us. On the one hand the battery: important to look carefully at how much capacity each model has. The autonomy is very variable and will depend a lot on how we record video: if we do in Full HD will last a little less than HD 720p, if we do with the WiFi on we can use it for less time …
On the other hand we have the compatibility with the accessories. Many manufacturers have decided to copy the hitch system that uses GoPro to use different accessories. From water proof cases to protect it from water and the selfie stick and supports of all kinds. The normal thing is that in most of the cameras that we see come with manufacturer accessories. Look carefully because having variety will mean using the camera more and being able to give it more uses.
Other AliExpress Action Camera Review 2017 details, such as the aperture of the lens or the type of slot used for the cards, should be taken into account. If we want to know the real quality of these cameras we will have to look beyond the technical specifications because although the manufacturers promise us sensors of much resolution, there are many important details that are not reflected with the naked eye.
And the native resolution to which it records? In the models we will see today in AliExpress Action Camera Review 2017, almost all the standard is Full HD at 60 frames per second. Some go up to 2K with 30 fps but none are still on UHD 4K. That remains the exclusive territory of the top of the range, at the moment.
As we said, not everything is sensor in these cameras and the quality of image will only see it thanks to videos recorded by other users. At the moment no manufacturer has managed to put a good sensor in these models and this means that what we record can have a quality far from what we expected at first. So our first advice when we are interested in a particular model is that we see some sample shots.
Great attention must be paid to compression artifacts. In digital photography are very common but today most of the sensors we use in cameras or mobile phones do not create many distortions. In low-cost action cameras it is easy to find these artifacts, that is, images that lose a lot of quality, fuzzy details, colors are not shown in a natural way …
Another important aspect that we sometimes overlook is image stabilization. We have an action camera, ergo we are going to move a lot and therefore we do not want the image to come out very trepidated or that when we mount the device in a fixed place (a helmet, the handlebars of a bike …) the video we record Vibrate and not allow us to enjoy a smooth image. Again: important that AliExpress Action Camera Review 2017 we review videos recorded with each model because in some cases the stabilization shines by its absence thus killing part of the grace of using one of these cameras.
If you look at the outside of the cameras, most opt for a fisheye type lens that allows us to take photos and record video with a wide angle. It also allows us the option to maintain the proportions but not all the cameras make a similar cut. Look carefully in AliExpress Action Camera Review 2017 because in some models you will see that much image is left behind when we move from one mode to another.
There is an aspect that tends to fall into oblivion when we record with an action camera and that is the audio. All cameras come with built-in microphone but not all capture the sound just as well. In some models, a lot of noise is shed to little wind blowing and in others it barely captures anything that is far away. Usually all make water and only a few give good results.
Special mention to the mobile application used by each manufacturer. This element will be the link that expedites the transfer of video and images to our smartphone so we can share directly with our friends and not have to pass the content through a computer and a USB cable. There are some who do very well as Xiaomi or SJ but others are quite disastrous.
AliExpress Action Camera Review 2017 small summary: look at specifications such as battery and compatibility with accessories. The sensor is an element that at first sight does not tell us much and it is best that we watch videos to check elements that are not seen by the naked eye: compression artifices, image stabilization, natural representation of colors … The application Mobile, without being a key piece, should work well so the experience of transferring files is not frustrating.
