Wiring an External Mic to a IP Camera
External Camera Cable Pin Out
** Here is an example of an option Mic “ETS ML1-S SURFACE MOUNT OMNI DIRECTIONAL SURVEILLANCE MICROPHONE” Try and Google to see more information…
There are 2 types of microphones: Active and Passive
- Active Microphones have a built in pre-amp, and require power to operate.
- Passive Microphones do not have built in amplifiers, however sometimes can require power.
Active microphones (LOUROE for example):
Depending on the pre-amp the Microphone might require:
* 12VDC. In this case the microphone has to be powered with a 12V DC power supply. These types of microphones are called LINE LEVEL MICROPHONES
* 1.8VDC – 4.5VDC. In this case the Microphone will be powered right from the IP camera itself.
These types of microphones are called MIC LEVEL MICROPHONES
Figure 1 shows the diagram of wiring a LOUROE LE070 LINE LEVEL MICROPHONE
After the camera has been successfully connected to the camera, it is time to change the camera settings, so that the camera can treat the microphone for what it is.
Log in to the camera:
- Go to “ADVANCED SETTINGS”
- Click on “VIDEO/AUDIO”
- Click on “AUDIO”
Microphone type to “LINE IN” if using a LINE LEVEL MICROPHONE
5.Change the Microphone type to “MIC IN” if using a MIC LEVEL MICROPHONE (FIGURE 3)
Passive Microphones are LINE LEVEL MICROPHONES.
When connecting a passive microphone to the camera, change the camera’s Audio Input setting to “LINE IN”.
Passive microphone wiring diagram is the same as FIGURE 1, with the only difference of having an OPTIONAL POWER SUPPLY(some passive microphones don’t require power, some – do)
