Follow these steps to connect a microphone to a PC-Based DVR:

Step 1: Obtain a Siamese (Power/Video) CCTV Cable long enough to connect your microphone to the pink audio input jack on the back of your DVR Server. View our various Siamese Cables in our eBay Store.

Step 2: Convert the cable into a Power/Audio Cable by doing the following:

1. Find the end of the Power/Video Cable that has the female Power Connector. This is the end to which the microphone's "power jack" will physically connect.
2. Connect the BNC end of the RCA/BNC Converter to the BNC connector on this end.
3. Then, plug the other side of the RCA/BNC Converter into the white "audio" jack coming out of the microphone.
4. Next, connect the "power" jack from the microphone into the "male" power connector on the Power/Video Cable.

Step 3: On the opposite end of the Siamese Power/Video Cable, connect a power adapter to the male power connector (thick, black plastic with a metal pin inside). Any in the range of 9V to 12V, with 200mA are acceptable. Connect the BNC end of the 1/8 Audio/BNC Converter to the BNC connector on this end. Then, plug the other side of the 1/8 Audio/BNC Converter into the pink "audio" input jack on the back of your DVR Server.

Now, your microphone should be properly connected. Feel free to contact us if you need more technical support.
