Not all HikVision IP cameras have Audio in/Audio out. Please refer to the specification sheet of the camera
for Audio capabilities.
As a rule of thumb, all INDOOR dome cameras and all BOX style cameras have 1 audio in and 1 audio
out 3.5mm audio jack.
Also, if the camera that has an optional (S) in the part number ( example: DS-2CD7283F-EIZ(S) ), than it
has audio in and audio out leads. There are some other leads as well. Please refer to the table below for

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

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).
Please note that the diagrams above are for specific microphones only. These diagrams are not universal,
and will not work for various microphones. Please consult the microphone manufacturer for wiring diagrams
and power consumption ratings.
