Important Safeguards and Warnings
Electrical Safety
Installation and operation should conform to your local electrical safety codes. The product must be
grounded to reduce the risk of electric shock. We assume no liability or responsibility for any fires or
electric shock caused by improper handling or installation.
Transportation Security
Heavy stress, violent vibrations, and moisture are not allowed during transportation, storage, or
installation.
Installation
Always keep the device upright and handle with care. Do not apply power to the device before
completing the installation. Do not place objects on the NVR.
Qualified Engineers Needed
All examinations and repair work should be done by qualified service engineers. We are not liable for
any problems caused by unauthorized modifications or attempted repairs to the device.
Environment
The device should be installed in a cool, dry place away from direct sunlight, flammable materials,
explosive substances, etc. This series product should be transported, stored, and used in the specified
environments:
The function of the ITE with concerns to IEC 60950-1 is considered now likely to require a connection to
an Ethernet network with an outside power source, including campus environments.
If applicable, the installation instructions clearly state that the ITE is to be connected only to designated
POE networks without routing to an outside power source.
Accessories
Be sure to use only the accessories recommended by the manufacturer. Before installing, please open
the package and check that all proper components are included. Contact your local retailer if something
is broken or missing in your package.
Before operating, please read the following instructions carefully.

Hardware Setup
Before setting up the NVR, you will need the following items. These items may not be included:
A computer monitor or TV with either an HDMI or VGA input
A power strip with room for 4 large power plugs
A hard drive for storing video recordings.
A USB flash drive formatted to FAT 32 for importing/exporting configure or image files.
It is recommended to connect all components before mounting any of the cameras. This is to ensure all
components are working properly before they are physically installed. If any components are not
functioning, please contact Amcrest Support: https://amcrest.com/contacts
There will be two parts to this section:
A hard drive must be installed to record or save any footage. If no hard drive is installed, you can only
view the cameras from the NVR. If a microSD card is installed in the camera you can still view the
recordings from the microSD card using the Amcrest View Pro application and accessing the camera
directly, however, no recordings will be retained to the NVR if a hard drive is not installed.
Hard drive installation
A hard drive can be installed if you want to record and save data to the NVR. Having a hard drive allows
you to configure and use the recording functionality of the NVR to store and view events.
Most NVRs have connections for only one hard drive however some models have the option for multiple
hard drives inside the case. A hard drive used in these NVRs must be no larger than 10TB (Terabytes). To
install your hard drive, the following is needed:
