Dear customer: Of course, the camera can also be used if you don't need to turn on the LED. Also, the camera could turn off the LED indicator for recording (no LED mode recording). You just need to press both buttons at the same time and you could just turn off the LED indicator to record. But when the camera battery life is low, the camera can only use the LED as a flashlight because the battery life is not enough for recording. (Therefore, please refer to the user manual about the camera's LED indicator if the battery life is insufficient.) Last but not least, the body camera's LED light level can be switched from 3 gears - high / medium / low, and there that is Warning mode If you long press the LED button, the red and blue buttons will flash constantly. We strongly encourage you to try it first. Also, we ensure the 1-year warranty and after-sales service. So don't worry about the quality of our body camera. 

No, it can be screwed on directly.
