3.3 Connection Port Information
3.3.1 Power Supply Connection
Please check to make sure the input voltage is correct and the power button is in the off position when connecting
the power supply.
We recommend you use an Uninterruptible Power Supply (UPS) to guarantee steady operation of the NVR, as well
as to elongate the life span of the NVR and other peripheral equipment such as attached cameras and other
accessories.
3.3.2 Audio Output Connection
The audio output signal parameter is usually over 200mv 1KΩ (BNC or RCA). It can directly connect to a low
impedance earphone, active speaker, or amplifier-drive audio output device. If the speaker and the microphone
cannot be separated spatially, it may create a feedback loop. In this case you can adopt the following measures:
•
Use a better directional microphone.
•
Reduce the volume of the speaker.
•
Using more sound-absorbing materials in the surrounding area can reduce voice echo and improve the
acoustic environment.
•
Adjust the layout of the audio output cables to reduce the occurrence of a feedback loop.
3.4 Device Assembly Guide
Before setting up the NVR, you will probably need the following items. The items are not included:
•
A computer monitor or TV with either an HDMI or VGA input
•
A power strip with room for 4 large power plugs
Note
: It is recommended to connect all components of the system as shown below BEFORE mounting any of the
cameras. This is to ensure all components are working. If any components are not functioning, please contact
Qcam Support.
To set up the NVR hardware, there are 6 major steps:
1.
Connecting a monitor to the NVR. The NVR is compatible with any monitor that uses a VGA or HDMI
connection. For purposes of this guide, we will use a VGA connection.
