Important Safeguards and Warnings
All installations and operations of the device should conform to your local electrical safety codes. We
assume no liability or responsibility for any of the fires or electrical shocks caused by improper handling
or installation.
We are not liable for any problems caused by unauthorized modifications or attempted repair. Do not
submerge the device in water or install in areas with high levels of moisture or humidity. Handle with care,
avoid from dropping or placing the device in unsecure areas. The NVR does not have rack mount
compatibility and should be used on flat surfaces.
Overview
Amcrest NVRs use a Linux based operating system to maintain reliable operation. The AI features listed
on the NVR include, “Face Detection, IVS, People Counting, Heat Map, and SMD (Smart Motion Detection).
The features available for use in the NVR will be dependent on the type of camera used on the system as
the AI features are controlled by the camera only. This device allows the user to implement the AI
features from an Amcrest AI camera into the NVR and store the recorded events.
Check Hardware
When you receive the NVR system in the packaging, unpack it, and check all sides of the device to see if
there is any physical damage. The protective materials used for the packaging can protect most accidental
damage during transportation, but to ensure that your equipment is operating as expected, it is
recommended to inspect the product before proceeding further.
On the NVR, check that the label on the NVR is not damaged. The serial number of the unit may be needed
if requesting support and is provides a QR code for a quick means of adding the device to the Amcrest
View Pro app on your mobile device.

Connection & Setup
The following instructions will show you how to set up the cables for the NVR, cameras (PoE and Wi-Fi),
as well as a monitor or TV screen.
To set up the cable connections, there are 5 steps:
1. Connect a monitor or TV screen to your NVR. The NVR is compatible with any monitor or screen that
uses a VGA or HDMI connection. For purposes of this guide, we will use a VGA connection. Take a VGA
cable, and connect one end to the VGA port on your monitor/screen and the other end to the VGA port
on the back panel of your NVR.
2. Connect an Ethernet cable to your router then connect the other end of the cable to the Ethernet
port on the back of the NVR.
3.Connect the cameras to power.
For PoE NVRs/cameras: connect an Ethernet cable to the Ethernet port attached to the camera then
connect the other end of the Ethernet cable to a PoE port on the NVR.
Note: PoE cameras can either be powered with a PoE connection or with a standard power adapter (sold
separately). If the NVR does not have PoE ports, connect the PoE camera to a PoE compatible router or
switch that is on the same network as the NVR.
For non-PoE NVRs/cameras: Connect the power adapter to the power port attached to the camera.
Then, plug the adapter into a wall outlet or power strip.
4. Connect the NVR’s power adapter into the power port on the back of the NVR.
Note: If your NVR has a 3-prong power cord, connect the input of the cord into the power input of the
NVR.
5. Finally, connect the other end of the power cable into a wall outlet or power strip to turn on the NVR.
Some models may feature a power switch on the back which may need to be turned on to power the
device.

Hard Drive Installation
Hard drives are typically sold separately, when installing a hard drive to the device, please make sure to
use a hard drive with 7200rpm or higher. Please follow the instructions below to install a hard disk drive
(HDD).
All the figures listed below are for reference only. Slight differences may be found on the front or rear
panel.
The NVR has connections for only 1 hard drive inside the case and the hard drive must be no bigger than
10TB (Terabytes).
To install your hard drive, the following is needed:
A medium sized (regular) Phillips-head screwdriver - not included
A hard drive - not included (unless you purchased a ‘kit’ that does have one included)
Four hard drive fastening screws - included
Note: Before installing the hard drive, make sure the NVR is powered off and completely disconnected
from power.
1. Loosen the screws on
the upper cover and side
panel.
2. Attach four screws in the HDD
(Turn three times.)
3. Place the HDD in accordance
with the four holes on the bottom.
4. Turn the device over
secure the screws.
5. Connect the HDD data cable
and power cable to the HDD.
6. Attach the cover onto the NVR
and secure it using the screws.
Once the hard drive is installed, turn on the NVR. If the hard drive for your NVR was not setup properly
you may hear a beeping noise. This indicates the NVR does not have the proper connection with your hard
drive.

Factory Reset Procedures
A factory reset will revert the device back to its original factory settings. To begin the process, you will
need to remove the NVR cover. Use a Phillips head screwdriver to remove the screws on the back/sides
of the NVR. Once the screws have been removed, lift the lid to expose the NVR's motherboard. Please
make sure the NVR is powered on as well to complete the process.
On the motherboard you will notice a small black button. This is the factory reset switch for your NVR:
To factory reset the NVR, press, and hold the factory reset switch for 4 –5 seconds and unplug the power
adapter. Once power is removed from the unit, press, and hold the factory reset switch for an additional
4 - 5 seconds and power plug the adapter back into the unit. Continue pressing the factory reset button
until you hear a beep and release. The device will be reset to its original factory settings.
Device Installation
After applying power to the NVR, the system will turn on. Allow the NVR to finish loading. The Device
Initialization screen will appear. Select your location, language, and video standard then click Next to
continue.

characters. A combination of letters, numbers, and symbols are recommended when setting up your
password.

Once you have entered a new password for your device, confirm the password in the next field. A hint for
the password is optional but is recommended in case you forget the password. You can also disable or
enable the unlock pattern toggle switch as this feature is optional. Click Next.

This is an optional security measure for your device. To set an unlock pattern, use your mouse to draw a
design that you will remember. Draw the pattern again to confirm. If you do not want to assign an unlock
pattern, you can click ‘Skip’to skip this process.

If you have assigned an unlock pattern, you will need to draw the pattern again to confirm your assigned
unlock pattern.
Password Protection
Additional means of password protection and retrieval can be set up in this menu. If you would like to
reset your password using your email, make sure the email address checkbox is enabled and enter a valid
email address in the Email Address field. The email address will be retained in the system.
If you do not want to use an email address you can disable the email address option. As a secondary
means of recovering your password, you can apply security questions to your NVR. To add a question,
select a question from the drop-down menus for Question 1, Question 2, and Question 3 and enter the
answers to those questions in the Answer fields.

address, click on “Modify” and disable the DHCP toggle switch. Click Save. This will set the network mode
to Static.
