Part 10 - Connect an Interface Adapter to a Microphone
A 10 Part GeoVision Series by Camera Security Now -- Featuring Brian Wood
In this GeoVision Configuration video Woodio explains how to connect an audio interface adapter to a microphone using an IF-1 from Louroe Electronics. If you need audio capture alongside your CCTV video surveillance, Camera Security Now can set you up with a Geovision DVR card capable of capturing both audio and video. Microphones will often times be installed in a different location than the camera, but both wires can be ran to the DVR and connected to an audio dongle with corresponding port numbers, so that video is captured and combined into one file with both audio and video.This video shows an example using only one microphone. For installing audio on just one of your cameras, the IF-1 audio interface adapter from Louroe Electronics
To get started first choose a spot to mount the interface adapter. This spot should be somewhere close enough to the Geovision server that the included RCA cables will be able to reach the Geovision audio dongle. Installing the microphone is easy. Mount the microphone where you want it, then connect the microphone wire to the microphone itself using the ABC terminal block. Run the wire from each microphone back to your Geovision server, where the audio adapter will also be located. This wire will transmit the audio signal to the audio interface adapter, and will also provide phantom power to the mic from the IF-1.
After you run the cable from each microphone to the audio interface adapter, connect the three wires to the A, B, C ports on the terminal block of the adapter. Use the included RCA cables for the IF adapter from Louroe to connect the RCA port on the adapter, to the corresponding port on your Geovision dongle. Once you have the audio properly hooked up to your DVR server, the Louroe Electronics audio interface adapters include an adjustable gain control that can be increased or decreased to give you more or less volume on the microphones.
The microphone in this video is the Verifact L-DT, also from Louroe Electronics. This microphone is pyramid shaped, and slightly larger than a deck of cards. The microphone has a nonslip bottom, and is intended to be placed on a flat surface like a tabletop. It also has mounting holes if a more permanent method is needed. One of the most popular uses of this microphone is in an interview situation, because it has two built in microphones working as one, which is ideal in a situation where two people are sitting across from each other.
