Review: Worked well - Arrived in a timely manner and worked very well with my dvr.
Review: USA Sales Group Paquete de 2... - I purchased this 2-pack of CCTV microphones to add audio to my DVR surveillance setup, and they’ve worked great so far. The high sensitivity picks up surrounding sounds clearly, which is helpful for monitoring outdoor activity or entrances. Installation was simple thanks to the RCA connection, and the built-in preamp ensures the audio signal is strong enough without needing additional equipment. I was also impressed by the solid construction, which gives confidence in long-term use. These microphones are ideal for basic audio monitoring and pair well with most standard security systems. Definitely a worthwhile upgrade for more complete surveillance coverage.

## 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.

### ⭐⭐⭐⭐ Works very well w/ Amcrest IP4M-1028EB dome camera
*by T***M on March 20, 2019*

I've installed 2 of these microphones outdoors under eaves of the house and shed. I purchased the 3 pack. Both exceed my expectation for outdoor microphones at this reasonable price. I've adjusted the sensitivity on both and can pick up soft voices from 30`. This is security microphone, tiny, and not for music so some digital artifacts are present at high sensitive settings (could be the camera / compression). Birds songs are pretty clear but not prefect (4 stars). I had DC power (12V) at both locations and I'm waiting on a 12v POE splitter for another location. Male and female plugs allow existing 5.5x2.1mm 12v power to "pass through" the microphone before powering the camera. The actual microphone sensor is about ~ 7mm/0.25" in diameter and 32mm/1.25" length needs to be exposed in order access the sensitivity screw. Not reviewed: performance in windy conditions, long term usage (>5 days), direct exposure to water, or bug resistance (i.e. Mud daubers).
