The most important thing to check before buying an action cam, yep! Camera resolution and quality. You can buy 720p and 480p resolution cameras, enough for everyday use. But if you have more budget, you can buy 1080p and 720p resolution. Also pay attention to the format of the resulting video, make sure the format is .mp4 with the H.264 codec so that it is easier to transfer to another gadget.
2. Waterproof
Usually now action cams are equipped with waterproof features, they can even survive to a depth of more than 30 meters underwater. The advantage of having this feature is that you don't need to worry when it rains.
3. Supporting features
Action cams are usually equipped with various supporting features, such as WiFi, Bluetooth, time lapse, battery life, exposure, wide angle. Try adapting these additional features to your needs so it can make things easier.
4. Needs and budget
It's best to readjust to your needs and budget. If you need to take everyday photos, you can look for an action cam at an affordable price, such as the Polaroid cube, Spectra XC1. But if your needs are professional, it is recommended to look for higher specifications.
