When using the audio input terminals on the rear of an ExacqVision Hybrid NVR, you will need a microphone with a a pre-amplifier capable of producing a line level output that can be connected directly to the ExacqVision audio terminal inputs.
If using a mic level output microphone, you will need a mic pre-amp to boost the audio to line level output for connection to the rear audio input terminals.
There are many options available in the market. The following is a list of some common choices:
- Louroe ASK-4 #101 Single-Zone Kit
- Louroe ASK-4 #102 Single-Zone Kit
- Louroe ASK-4 #104 Four-Zone Kit
- Louroe ASK-4 #108 Eight-Zone Kit
- AKG PZM10 LL Microphone with line level output
- AKG PZM11 LL Microphone with line level output
- ETS SMI-9 Eight-Zone Kit
If you choose to use other surveillance or boundary layer microphones with mic level or XLR connection outputs you will need an intermediary device that provides a line level output to use with the audio input terminals.
