## 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.

### ⭐⭐⭐⭐⭐ Very Low Noise - Best out of four I have tried.
*by J***C on June 12, 2023*

I was expecting same poor quality AC sounding hum. I monitoring honey bees so low frequency performance is important. I don't have to use noise reduction at all! I ordered two. I might order two more.(Update 4/7/2024 Great unit. I can not not over express how good the audio quality from this mic is. I use it to stream and record Honey Bees. A wind muff made this superb even in the wind. Every other mic I have tried has a low hum/noise in the same frequency ranges as bee hums and buzzes. However, definitely not directly weather proof. Ran for an entire year of direct exposure. I have a second unit. This would work great inside a protective compartment. I think inside a void in a camera mount housing is the intent. I am looking for a little plastic tip and then going to dip it in silicone. Thinking of an angle I can drill in entrance reducer block of wood that slips in the front of hive. I ORDERED TWO MORE! )

### ⭐⭐⭐⭐ They work well, but suffer from wind noise. A wind sock would help.
*by C***K on January 29, 2020*

This review does NOT include a reasonable complaint about the microphones. They work and they work well. They have held up for over a year. I would get these again without hesitation.The first thing to consider is you will need to buy the cables that will allow you to use microphones. Some cables may come with fittings for these but many do not. I have seen BNC cables with 3 ends. The extra fitting is for microphones to use. The cost of additional cables is an additional expected expense. If you want sound then you have to buy both microphones and the cables needed to bring the sound to your recorder.Installation of the microphones confused me at first. Then I discovered that it was really simple. Unplug the power wire from your camera. Plug that power wire into the microphone power in plug. Next plug the power out end of the microphone into the power in plug of the camera use the other connector as required and you are finished. It was harder to figure out than it was to install.Why only 4 stars? At this price point we can not expect noise cancelling ability. The microphone can pick up a lot of wind noise. The solution is to make a windsock of some type that fits over the microphone designed to reduce or maybe even eliminate wind noise. This microphone is not only lacking a wind sock but no wind sock is offered as an extra cost option.I know adding a wind sock would increase the price somewhat. It would greatly improve the microphones capability if it was offered. Because a wind sock for noise reduction is neither included nor offered as an accessory I took 1 star off. If a wind sock was included or available as an extra cost option I would upgrade this to 5 stars.EDIT: These microphones have held up for over 3 years now with no issues. They are plenty sensitive. I still wish they offered a windsock to reduce or eliminate wind noise.
