The analog video output (composite video) contains the video from the camera combined with On-Screen
Display (OSD) overlays such as detected objects, tracking boxes and trails, time stamp, alarm, camera
status, and so on. These OSDs can be enabled and customized using the unit’s embedded web interface.
The analog video output can be monitored using an analog monitor or recorded on a digital video recorder
(DVR). For more information, refer to the HTML Edition Units User’s Guide.
To connect the unit analog video output to an analog device
 Using video coax 75Ω cable with BNC connectors, connect the Video Out of the encoder to the
analog device’s video input (for example, the VIDEO IN of a monitor or DVR).
Note:
Make sure the encoder and the external analog equipment support the same video standard
(PAL/NTSC).
3.2.6 Connecting the Unit to Receive Alarms from External Devices (Alarm Inputs)
The unit supports receiving alarms from external devices such as sensors and doors, enabling it to trigger
automatic responses on the unit.
Warning:
Only dry contacts can be connected to the unit’s alarm input terminals. An external device
must fully close or fully open the circuit between the unit’s alarm input terminals.
The unit supports a single alarm input from an external device. The alarm input includes two connecting
terminals.
To connect an external alarm to the unit
Warning:
Disconnect power from the unit before performing the following procedure.
1. Connect the leads from the external device dry contact output using the spring clamp terminal
block into the terminals marked - (Alarm In) and + (Alarm In). See Connecting Leads to a Spring
Clamp Terminal Block (page 18). The two terminals are located at the bottom of the terminal
block. See Figure 3: trk1 Power Connection Panel.
2. Connect the terminal block to the external devices connector on the power connection panel of
the unit. See Figure 3: trk1 Power Connection Panel.
3. Connect the other end of the cable to the alarm out (dry contact) of the alarm device/sensor.
3.2.7 Connecting the Unit to Control an External Device (Using Relay Outputs)
The relay output of the unit provides an indication signal for controlling external devices, such as door locks
and lights as a response to events and alerts. For more information on incident responses and relay
outputs, refer to the HTML Edition Units User’s Guide.
