Observe the following safety factors:
•Is there visible damage to the system or power cord?
•Is the system operating correctly?
•Has the system been exposed to rain or moisture?
•Has the system been in a long storage under harsh conditions or exposed to unconforming stress?
The relevant electrical engineering regulations must be complied with at all times during installation.
Ensure that all maintenance and repair work is handled by qualified personnel such as electrical engineers or network specialists.
Read this manual before installing or operating the system. The documentation contains important safety instructions about permitted uses.
The rated AC input is: 100-240V~ 2-1A, 60-50Hz; the max. consumption: 120W (DC56V, 2.5A)
If a fault occurs, disconnect the power cord from the power supply.

NOTE:
You can also use the Reset button to restore system defaults. Press and hold down the button for longer than 5 seconds. The system should start restoring defaults.
IMPORTANT:
It is important to leave a clearance of 25cm behind the chassis. The clearance is required to ensure an adequate airflow through the chassis to ventilate heat.
To ensure normal operation, maintain ambient airflow. Do not block the airflow around chassis such as placing the system in a closed cabinet.

2 Hardware Installation
SATA hard disk(s) are user-supplied. The network video recorder can readily accommodate most of the off-the-shelf SATA hard drives.
1. Use a screwdriver to loosen the retention screw on the sides of the chassis. Slide the top cover back, and then remove the top cover.

VIVOTEK - Built with Reliability
NOTE:
Although the system supports MAC Binding, the system should be able to detect VIVOTEK's cameras within the network regardless of the presence of a DHCP server. Ideally, cameras and the NVR should reside in the same subnet. If a camera's IP is changed for some reasons, the system should be able to detect its new IP.

Terminal Block Connections
The terminal block pinouts is shown as follows:
The DO pins default status is set to Normally Closed. Connect your relay or external devices’ signal wires to the system, the system will automatically detect the current signal status. You can then trigger the external devices using the DI/DO panel on the live view.
You can also configure the system alarm setting for the system to automatically trigger a DO on the occurrence of system events. See Alarm settings on page 75.

4 Initial Configuration - via a Local Console
A local console requires the following:
1.A monitor is connected via an HDMI or VGA cable.
2.A mouse and/or a keyboard are connected to the system.
3.It is presumed that the system has not been configured yet.
Follow the onscreen messages to complete the initial configuration:
1.Select the UI language, Time zone, and current date and time. Click on the Continue button to proceed.
IMPORTANT:
Except in the initial setup, changing system time can produce disruptions to the existing recordings. Turning the current system time back to a time when video recording was taking place can generate duplicate files. And those files may not be playable.
2. The system will then start to scan the local subnet for connected cameras.

4.The system will automatically create volumes from the installed disk drives. The process will take several minutes.
5.An optional utility, EZConnect, is available through the Apple and Android App Stores. The EZConnect works with a server hosted by VIVOTEK for bridging and tunneling video requests between client devices and network cameras/CMS/NVR. The utility simplifies and facilitates network configuration for access across the Internet.
The prerequisites for using the EZConnect are as follows:
1.Download and install the EZConnect utility to your cell phone.
2.Both the NVR and your cell phone have access to the Internet.
With this utility, you do not need to configure IP port forwarding on router or set up a DDNS address for the NVR. You do not even need to know the IP address of the NVR. The EZConnect utility automatically manages the network parameters required for making the connection. The EZConnect comes with viewing and playback interfaces very similar to those in the iViewer utility.
To connect the NVR from a cell phone using the EZConnect: 5-1. Click on the EZConnect button on the wizard.

6 Power Up and Power Down
To power up and power down,
On the initial configuration:
1.Connect the power adapter between the system and power outlet.
2.Turn on the system by pressing the power button for more than one second.
After the initial connection,
1.Press the power button for 1 second to power on.
2.Press the power button for 4 seconds to power down. The system should start flushing the cached contents in system memory and gracefully shut down.
Press the Reset button for longer than 5 seconds can restore system defaults.
WARNING:
1.No storage system is completely fail-safe. Damage to data might occur due to file system corruption, operating system malfunction, virus infection, HDD component failures, and so on.
Therefore, it is highly recommended to regularly back up your data, and VIVOTEK disclaims responsibilities of data loss or recovery.
2.Always power off the system using the power button. Do not disconnect the power cord while the system is still operating. Doing so will result in data inconsistencies. The normal power-off procedure allows cached data to be written to disks.
NOTE:
If system buzzer is sounded, move your mouse cursor to reveal the main screen portal, and then click on the Stop buzzer button.
Serious system faults, such as a missing volume, can trigger the system buzzer. Verify the cause of system fault and turn off the buzzer.
