Not buying is not possible. Wiring is wrong.

Will not work with an aftermarket security system. Useless product. It's too late to return it, but it doesn't fit the normal cables that come with every security system.

Pros
  • 🎤 The microphone comes with a combined power and audio cable, a 1-foot cable with an RCA audio connector and a 2.1mm positive center plug. Catch every sound with an ultra-high gain micro audio system. On-chip integrated preamp, low noise, high gain, and automatic level control

Buyers be careful, but Revain

NO reply from seller after 2 emails! Didn't work on my Samsung 75100 cctv. The 4th did not cover the shiny silver microphone. No other visible damage although they were only in a plastic bag thrown into a large box with a large bag of growth stone. time and trouble.

Pros
  • will fix the situation.
Cons
  • I don't remember but there was something

DO NOT work with Swann Security Cameras - LOUD Buzz/Click

These mics WILL NOT WORK with Swann Security Cameras. All four microphones are either defective or incompatible with my particular setup. All four microphones make a loud buzzing/clicking noise and the microphone audio is very weak. Instead I bought mics from USA Sales Group and they work great. The adjustable gain ones sold by the US sales team work as intended and pick up everything - NO hum/clicks.

Pros
  • 🎤 If you are not satisfied with our products, please contact our customer service team.
Cons
  • Not the best

Incorrect composition of the circuit and design

This microphone circuit design is the root cause of the problem. The mic is fine, but the circuitry uses a 386 non-feedback linear amplifier chip. This chip itself was originally designed to deliver 1W of output power to small headphones or a small speaker, but not for line out. So the problem here is that when the mic is picking up loud sounds, it will clip the line input of any line level circuitry. I've tried to fix this by adding a feedback resistor to reduce the output level gain, but it…

Pros
  • 🎤 No noise, no loud buzz (buzz) - a clear sound is captured and there is no buzz with any kind of interference. It picks up 25 to 50 feet depending on where it's installed next to a reflective wall. Attention, if water is poured on it, it will stop working. Try to install the microphone in a place where it will not be exposed to rain.
Cons
  • I vaguely remember
