Please tap the camera “setting” icon > tap “Motion Detection” > tap “Duration” and select the duration you want.
There are 10s, 15s, 20s, Auto to choose from.
If you select “10s”, “15s”, or “20s”, the recording duration will be fixed 10s, 15s, or 20s. If you select “Auto“, after the PIR sensor is triggered by a movement, the camera will record a video up to 3min if the movement continues. However, please note that the camera will consume more battery power in “Auto” mode because it keeps working in this mode.
