High Sensitivity Adjustable CCTV Microphone 008/US

Arrived in a timely manner and worked very well with my dvr.

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.

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).

Worked great right out of the box! My camera is P.O.E. (power over ethernet) so I had to add a power supply but I knew that from the start. It has a gain adjustment but never touched it because it sounded great from the factory.

Works great for my DVR audio input

I bought this as a replacement microphone for the one that came with my Chinese PTZ camera and only lasted until the first rain. So far it has held up against the elements, especially heavy rain with no issues. I love its small and stealthy footprint. Sound quality and sensitivity are impressive for something in this price range. I'm using it with the G.726 codec (8kHz sampling rate) and adjusted the input level on the camera, rather than messing around with the little gain screw on the mic itself. I'll probably cover the adjustment screw with electrical tape to make sure no water and dirt are getting in over time. The noise level is low enough to clearly pick up the first crickets of the season and even things like a plastic tarp gently flapping in the wind. Environmental noises like cars and birds are crisp and clear for a CCTV system. I haven't had a chance to eavesdrop on a conversation yet, but my cats certainly approve of the authentic replication of the bird sounds on my property :) Update: After a recent rain shower it is now dead. It lasted only a little over half a year, which is why I'm knocking off two stars.
