Chapter 2 Unpacking Inspection and Cable Connections
2.1 Unpacking
When you receive the product, first inspect the package for visible damage. The
protective packing materials used for the product can handle most accidental shocks and
impacts during transport.
Then, take out the device, remove protective film from the DVR, and inspect the product
for any visible sign of damage.
Finally, open the case to check for loose connections to front panel data cables, power
cord, power supply to fans and motherboard.
1.Front and Rear Panels
♦ Refer to the user manual for details on the functions of various front panel buttons
and rear panel connectors.
♦ Please verify carefully the product model on the front panel plaque and make sure it
is the model you ordered.
Do not tear off the label on the rear panel as it is extremely important to our post-sale
service. When you contact our post-sale service, you will need to provide the model
number and serial number printed on the label.
2.Items to be checked after opening the case
In addition to checking for visible damage, please inspect for any loose connections to
the front panel cables, power cord and motherboard.
2.2 Rack mount
The product uses a standard 1U chassis and can be mounted to a standard rack.
Installation procedures and precautions:
1、Make sure the room temperature is below 35° C (95°F);
2、Allow 15cm (6”) clearance around the product for proper ventilation；
3、Always fill the rack from bottom up；
4、Consideration should be given to protecting the rack from circuit overload when mounting multiple
Page 7
units to the rack.

2.5 Audio/Video IO Connections
2.5.1 Connect Video Input
The DVR has BNC video input connectors. Signal requirements：PAL/NTSC BNC（1.0V，75Ω）。
Video signal should conform to the national standards with a higher signal-to-noise ratio, low
distortion and low interference; requiring picture to be clear, with no image distortion, with natural color
and appropriate brightness.
Ensure stable and reliable camera signal:
Install the camera in appropriate locations to avoid backlighting and surroundings with dim light or
use low illumination camera and camera with effective backlight compensation.
Cameras should share reliable common ground with the DVR to ensure the normal operation of the
camera.
Ensure stable and reliable line transmission of signal:
Use high-quality, shielded video coaxial cable. Select the right type depending on the transmitting
distance. If the distance is extensive, you should consider the use of cable with twisted pairs, video signal
enhancing devices and fiber-optic cables to maintain the signal quality.
Keep the video transmitting line away from other devices and circuits that generate strong
electromagnetic interference. In particular, protect it against high voltage power surge.
Ensure secure wire connections:
Page 9
Signal lines and shielded cables should have tight connections. Avoid false soldering and prevent
oxidation of the solder connection surface.
2.5.2 Selection and Connection of Video Output Devices
PAL/NTSC BNC (1.0V
, 75Ω) video output and VGA output exist （ They can operate
P-P
simultaneously）
When using a computer monitor as an alternative surveillance display, pay attention to the following:
1. In order to prolong the life of the equipment, do not leave the monitor power-on for an extended
period of time；
2. Perform demagnetizing regularly to ensure proper working status of the monitor；
3. Keep it away from devices generating strong electromagnetic interference.
TV is not a reliable alternative as the video output device. It also requires minimizing the power-on
time and tight control of interference from surrounding power source and devices. Possible electricity
leakage from low quality TV could result in damage to other devices.
2.5.3 Audio Signal Input
AV interface for audio input.
With higher impedance, active pickup is required.
As with video input, the audio transmission line should minimize interference, prevent inadequate
soldering and faulty connections. Pay special attention to protection against a high voltage power surge.
2.5.4 Audio Output:
The parameter of the DVR audio output signal is usually greater than 200mv 1kΩ (AV). It can be
directly connected to low impedance headphones, powered speakers or drive other audio output devices
through an amplifier. If spatial isolation cannot be established between external speakers and pickups, it
could result in a whistling sound. In the event, you may:
1、 Use pickups with better directivity;
2、 Adjust speaker volume to the level below whistle threshold;
3、 Use sound-absorbing materials in the working environment to reduce sound reflection and
improve room acoustics;
Page 10
4、 Adjust the layouts of pickups and speakers to reduce the occurrence of whistling.
３３３３.Connections to PTZ
A. The PTZ decoder must share a common ground with the DVR or possible presence of
common-mode voltage may cause you to lose control of the PTZ.
We recommend shielded twisted pair cable with its overall shield being used for common
ground;
B. Prevent against high-voltage power surge. Wire cables must be able to protect equipment from
lightning
C. Connect a 120 Ohm resistor in parallel at the far-end to reduce reflection and guarantee the
signal quality;
D. The AB-wire connections of the DVR’s 485 cable cannot be combined with 485 cables from
other output devices;
E. AB line voltage of the decoder should be lower than 5V.
4. Ground Wires of front-end equipment
Incorrect grounding may result in chips being burned.

Chapter 3 Basic Operation
Note：Grayed out button means the function is not supported
3.1 Turn Power On
Connect the unit to a suitable power outlet before turning on the power switch on the
rear panel. Power indicator light is on and DVR starts booting. When the booting is
finished, a “beep” is heard. Multi-screen is the default video output mode. If the unit is
turned on within the scheduled recording time period, the system will start scheduled
recording automatically. Recording indicator on the corresponding channel turns on. The
system works normally.
Note: 1. Before turning on the power, make sure the mains voltage matches sliding switch of the unit and
the power cord is connected correctly.
2. External power supply requires 220V±10% /50Hz.
We recommend the use of power supply with stable voltage and less ripple interference.
Whenever possible, consider the use of UPS for power backup.
3.2 Turn Power Off
The unit can be turned off using softswitch and “hardswitch”. Softswitch, Select 【Turn
Off】in【Main Menu】>【Shutdown System】； Hardswitch，Press the power switch on the
rear panel to turn off the power.
Instructions:
1. Power failure recovery
If the DVR is shut down unexpectedly during recording, after the unit is rebooted it
will automatically save the data before the shutdown and return to where it was.
2. Replacing hard drives
You must turn off the rear panel power switch before replacing the hard drive.
3. Replacing batteries
Save the configuration information and turn off the rear panel power switch before
Page 12
replacing batteries. The DVR uses button batteries. You need to check the system time
periodically. Batteries need be replaced when the time becomes inaccurate, we
recommend replacing batteries of the same type once every year.
Note: Save the configuration before replacing batteries on the motherboard or
the configuration information will be lost.
3.3 Log in
After normal start-up, the operator is asked to log in. The system will provide
corresponding functions based on user permissions.
Factory default setting provides 3 user types with no password: admin, guest, and
default. The factory setting of admin user has superuser permissions while the defaults
for guest and default are limited to preview and playback. Admin and guest users may
change their password but cannot change the permissions. Default user is a default
login user. Default user may change permissions but not the password.
Figure 3.1 Log In
Password protection: If the password is entered incorrectly on 3 consecutive occasions, the
system will display a warning alarm; After 5 consecutive attempts, the account will be locked
(The account will be unlocked automatically upon system reboot or after 30 minutes).
For security reasons, please change your User ID and Password under “User Management”
(refer to Chapter 4.5.2 User Management) after initial login.
3.4 Preview
After normal login, the unit shows the preview screen. Right click the mouse to switch
displays.
