Adding an External Microphone to a IP PTZ Camera

PTZ IP cameras for outdoors do not come with a built-in mic for weather proofing reasons. In order to record audio along with your security video, you have to use an add-on security camera mic of some sort. CCTV Camera World has microphones for both indoor and outdoor applications. Having an external microphone provides more flexibility when recording audio as you can run the microphone to a different spot from where the camera is installed. Setting up the wired connections between an external microphone and one of our IP Pan Tilt Zoom cameras is simple and explained in this article.

Equipment Needed

Here are links to the items you will need to accomplish connecting an external microphone to your IP camera:

Next, we'll explain how to connect the items mentioned above to an IP PTZ camera.

Wiring Setup for IP PTZ with Two-Lead Audio Input

Audio-capable Pan Tilt Zoom network cameras will have either an RCA audio input jack or a two-lead wire audio-in. Here, we will show how to set up an PTZ camera with a two-lead wire audio input. We will need to use a video balun to conform to the two-lead audio-in on the PTZ camera. For cameras with an RCA audio input jack, a balun will not be necessary and is discussed in the next section.

  1. The microphone will have a pigtail with two ends - a RCA Female jack, and a female power jack. Connect the female power jack to a 12V DC power supply and connect the power supply to a 110V power outlet.
  2. Connect the RCA female jack on the microphone to a video balun using an RCA Male to BNC Male connector.
  3. On the other end of the video balun, connect the two-lead audio-in from the IP PTZ. White wire is positive (+), black wire is negative (-) when plugged in to the video balun.
  4. Follow the instructions in the section titled "Configuring Your IP Camera to Detect an External Audio Source" below on how to configure the camera to detect the external microphone.

Wiring Setup for IP Camera with RCA Audio Input

If your IP security camera has a RCA audio input rather than a two-lead  wire for audio input, then the wiring setup is slightly different. Below is a wiring diagram when using an IP camera with an RCA audio input.

  1.  Like in the previous setup, connect the female power jack to a 12V DC power supply and connect the power supply to a 110V power outlet.
  2. Connect the RCA female jack on the microphone to the RCA female jack on the IP camera using a RCA Male to RCA Male connector.
  3. If you need more distance in between the camera and microphone, you can use an RCA cable with RCA Male plugs on each end to bridge the RCA input on the IP camera with the RCA input on the microphone.

Configuring Your IP Camera to Detect an External Audio Source

Some of the IP cameras we sell here at CCTV Camera World allow for an external audio source to be added. Please refer to the camera description and/or specs to determine whether your camera has an audio-in jack. For those cameras with a RCA audio input jack or a two-lead wire audio interface as described in the wiring setup above, you have to configure the camera to detect the microphone connected to the audio-input of the camera. The video below shows you you how to configure the audio input levels, and other settings. It also has a video/audio sample of our indoor security camera mic being using indoors along with our IP cameras.
