First impressions: Stable, durable construction. Solid built. Fright when you discover that there is no viewfinder, but aja. There you knew when you bought.
Picture quality: I have used 4k S and the normal 4k mode and then looked at it on a 4K UHD 65 inch screen. And I must say that the quality is incredible. Razor-sharp picture with tremendous depth of color. Clean and clear tones. With 24 fps, the picture is stable and flexible.
Audio: Here flaws Dett little. You can use a non-water / sand-tight protection and get some better sound, but they want yes to have the original shell on. And then the sound back. Quite OK, but you should record his daughter singing in school so you should probably get a different camera, with surround sound for example.
Adjustments: If you connect the camera to your phone or iPad, it's easy to make settings. And you have to. You can do this manually on the camera, but it's much more fun and easier to do it on their smartphone. Clicking just a few clicks of the camera and get it to identify itself, then scans to the wifi with their mobile and can easily find their camera. after verifying his camera so you can save it to your wifis.
Miscellaneous: Once paired dej via WiFi, you can update the system software and keep it up to date for best funtion. I did it and it went very smoothly.
If you launch the app on your mobile you can from there start the camera. So if you set it up outside the front door, you can put it on when it knocks.
That's when you use it maybe the coolest feature. It is streaming live from the camera to the LCD on mobile. So you can attach it to your helmet on his children playing in his room, and live to see everything the child does later in the LCD when you are in the kitchen and cooking. Skithäftigt.
Highly recommended if you want a good action camera. Quality and functionality are superb.
