3 Installation and Connections
3.1 Connecting Power Supply
Please check input voltage and device power button match or not.
We recommend you use UPS to guarantee steady operation, DVR life span, and other peripheral equipments operation
such as cameras.
3.2 Connecting Video Input and Output Devices
Video output includes VGA output and HDMI output.
System supports VGA and HDMI output at the same time.
When you are using pc-type monitor to replace the monitor, please pay attention to the following points:
•
To defer aging, do not allow the pc monitor to run for a long time.
•
Regular demagnetization will keep device maintain proper status.
•
Keep it away from strong electromagnetic interference devices.
Using TV as video output device is not a reliable substitution method. You also need to reduce the working hour and
control the interference from power supply and other devices. The low quality TV may result in device damage.
3.3 Alarm Input and Output Connection
Refer to the following sheet for alarm input and output connection.
You can select two alarm input types: Normal Open (NO) and Normal Close (NC).
1. Alarm input
a. Make sure alarm input mode is grounding alarm input.
b. Grounding signal is needed for alarm input.
c. Alarm input needs the low level voltage signal.
d. Alarm input mode can be either NO (Normal Open) or NC (Normal Close).
e. When you are connecting two DVRs or you are connecting one DVR and one other device, use a relay to
separate them.
2. Alarm output
The alarm output port should not be connected to high power load directly (It shall be less than 1A) to avoid high
current which may result in relay damage. Use the contactor to realize the connection between the alarm output
port and the load.
