Outdoor Microphone Questions???

[Johnnyseconal 0]

I have a really cool 8 camara with a Q-see Dvr running.....

Anywaysssss

I think its Legal in my area to have a Microphone with my security setup.

I bought a Microphone package(100 feet of Cable,Very slim Mic and power supply plug}

My question as I have been reading ,If i use this Mic.It will pick up all sorts of outdoor noise.

Well I hooked the Mic up to my outside deck

When I try to listen to the cars that drive by on my sercurity cams.

It seems that there is lots of wind and local noise from houses near by.I put a little foam on the mic to get rid of the wind,,,,,butttt

My problem is when I turn up my speakers to hear the Cars that drive by,I gets lots of Echo from my speakers where I have to leave

them on very low and I can hardly hear the cars that drive by.

I was thinking about a Computer Mic but I think that will also give me echo when speakers are turned up high.

I know these Mics picks up everything like when I am listening to my Tv or closeing my door.

Is there a fix for me?Or is there another Mic i can get to solve

this problem?

What about if I buy another outdoor security cam with a Built in Mic????Would that help????

Its just very annoying to be able to hookup my mic to my Dvr and

not able to use it..Maybe I need to buy better computer speakers???Just very annoying to turn the speakers to High and getting Loud Hummmmmm......Thanks to alllll...........JS

The "echo" you're getting is feedback, and it's caused by the microphone picking up the sound from the speakers.

 

Try moving the two further apart, and closing the windows.

It seems that when I move my speakers aways I will still get a loud Hum when I turn my speakers ways up.

I can hear the Hum from another computer states aways when

checking to see if its me or the Mic.

As a last resort

Would I still get the Hummmm if I buy a New Outdoor cam with a built in Mic??? Thanks for your time..Unless someone knows a better solution lol..........JT

Really depends what the source of the hum is... it's not the same as feedback; I suspect it's related to grounding. A camera with built-in mic may or may not work better - it's really impossible to say from here.

Its not bad the Hum when the computer speakers are on low but then again you will not hear the cars lol.

But if I turn my computer speakers very high the hum gets,,,,

hum,hummm,hummmmm,hummmmmmmmmmmm

Maybe its the speakers?

One person wrote this on the Internet let me paste it....Thanks JT

 

 

Turn any mic way, way up and you may hear the rumble from your home's fridge motor, furnace, AC, cars on distant roads, etc (a general low frequency rumble). Also, the more you turn it up the more "line noise" you hear. Line noise sounds like static and can become so loud that it drowns out the distant noise you want to hear. WARNING: Opening a door or speaking anywhere near the mic with the volume cranked up will blow the headphones right off your head and probably ruin your hearing too. Please note that most security DVR systems do NOT have an audio gain control or volume knob. Audio gain in a security system might be useful to folks who complain that a certain mic only recorded things a few feet away!

That person is wise.

 

Fact is, setting up a mic is very different from setting up a camera - it's difficult to be "selective" about what you pick up, especially since most cheap mics are "omnidirectional" and pick up everything in every direction.
