5.1.3 Connecting the Encoder’s Video Output to an Analog Device
The encoder’s analog video output can be monitored or recorded on analog devices. The output
analog video contains the video from the camera combined with On-Screen Display (OSD) overlays
such as tracking boxes and trails, time stamp, alarm, camera status, etc. These OSD overlays can be
enabled and customized using the HTML setup application. For more information, refer to the HTML
Edition Units User’s Guide.
To connect an analog device to the encoder’s analog video output
 Using a 75Ω coax cable, connect the VIDEO OUT of the IOI-XTRK-10D to the analog device’s
video input (e.g. the VIDEO IN of a monitor).
5.1.4 Connecting a Microphone to the Unit
You can connect an audio input device, such as a microphone, to the unit in order to listen remotely
to sounds near the camera. You also can connect a separate audio input device for each camera
channel.
Figure 9 - Microphone Connection to the Unit
The audio input to the unit is connected to a LINE IN interface and must meet the following
specifications:
 Input impedance: 10k Ω
 Input capacitance: 30 pF
 Maximum input level: 2 Vrms
 Minimum detectable input level: 20 mVrms
To connect a microphone to the unit
1. Connect the supplied audio splitter cable to the AUDIO IN/OUT port located on the front
panel of the unit. See Figure 3 - IOI-XTRK-10D Front Panel (page 3).
2. Connect the audio device (microphone/amplifier) at the other end of the audio splitter
cable to the AUDIO INPUT RCA connector.
3. Connect the microphone to the amplifier.
