## Questions & Answers

**Q: Do i need to hook up power to this mic for it to work? i have ip cameras and the power for the camera is running through the cat6 cable.**
A: Dear Ryan,
Thanks for your question. If the power for the camera is running only through the cat6 cable, then you need a separate power supply.
 For example, DC12V 0.5-1A. If the camera has another power connector, then you can take the power here. Usually, it happens.

**Q: I am currently using this same type of microphone, but it does not have the gain control. What would be the advantage of this product?**
A: This type of microphone is more sensitive than others. The microphone picks up a cleaner sound. The radius of picks up of a pure sound is more than other models. You can adjust the sensitivity of the microphone.

**Q: There are three connectors. Obviously one is power, and one is audio signal, but what is the third, and which is which?**
A: Hello, Dear Chris Miller,
Many thanks for your question.
The red cable is for power. White RCA is for audio.
The black cable for power the camera.
This microphone is designed to be used with a camera together if you are not using a camera, the black cable is not used.

**Q: how does the sensitivit adjustment works?**
A: Hello Dear,
Many thanks for your question.
The sensitivity adjustment is automatic.
Clockwise to turn up the volume.
