Camera Lens
1.What if I scratch the camera lens ? Can it be replaced ?
Really sorry that this is man-made damage, which is not covered by the warranty. We
have confirmed with our engineer, and he said that it is hard for your to replace the
lens.
2.Why there is always a dot on the photo and video I took ?
First, please clean the water-proof case and the camera lens.
Maybe you have set the exposure too high. We suggest you default the camera.
If the problem still exists, please contact the CS team.
3.Is the camera lens adjustable ?
This camera enjoys fixed 170 wide angle lens.
Videos and Photos
1.Why each video I get is less than 15 minutes ?
It's normal that the video file will be divided into many files.
As you know, this camera supports Class10, FAT32 SD card. So every video file is
restricted within 4G, about 8-15minutes. When the length of file is up to 4G, it will
automatically stop and then record a new file, and the new file will repeat a little from
the previous file. Almost every action camera with Class 10,FAT 32 SD card exists
this problem. Hope you could understand it. Also since the camera cannot recognize
when the file reach 4G, so it will cut the video automatically at about 8-15 minutes
even you use 1080P resolution.
Therefore we suggest you turn off the Loop Recording in the settings, and save the
files in the length of every 4G file.
2.Why the videos look so dark at night, but photos look better than videos?
We have contacted the engineer and he said this is normal.
1). While working in dark environment, the image quality of digital camera will
definitely be influenced, and you can use a flash light if needed;
2). The higher the camera resolution, the larger the noise in the dark environment;
3). The working principle of static image and motion image is different and it is not
comparable.
