2.6 Audio & Video input and output connections
2.6.1 video input
NVR video input port to the BNC input signal requirements: PAL / NTSC BNC (1.0VP-P, 75Ω).
Video signal should comply with national standards, a higher signal to noise ratio, low distortion, low
interference; image must be clear, invisible change, real and natural colour, brightness is appropriate.
Ensure stable and reliable camera signal:
Cameras should be installed in a suitable location, to avoid backlighting, low light conditions, or the use
of good results backlight compensation cameras, low-light cameras.
Camera and NVR power supply should be common ground, and reliable, in order to ensure the normal
operation of the camera.
Ensure stable and reliable transmission line:
Using high-quality, shielded coaxial good video, and based on the transmission distance to choose the
right model. If the distance is too far, should be based on the specific circumstances, the use of twisted
pair, add video compensation equipment, fibber optic transmission and other ways to ensure signal
quality.
Video signal line should avoid strong electromagnetic interference to other equipment and lines,
especially should avoid high-voltage current string into.
Lugs ensure good contact:
Signal and shield lines should be firm, well-connected, avoid Weld, lap welding, to avoid oxidation.
2.6.2 Select and connect the video output device
Video output is divided into PAL / NTSC BNC (1.0VP-P, 75Ω) output and VGA output (VGA is optional)
Choose to use computer to replace the monitor should pay attention to the following questions:
1. Do not keep long boot state to extend the life of the equipment;
2. regular degaussing, which will help maintain the normal operation of the display;

10
3. Away from strong electromagnetic interference devices.
Use TV as a video output device is an unreliable alternative. It also requires minimizing the use of time
and strictly controls the interference power caused by neigh boring devices. Inferior TV leakage risks
may cause damage to other equipment.
2.6.3 SDI video output
Some models support coding for 1080P (720P) SDI video.
2.6.4 Audio input
BNC connector (only one to support intercom function)
Audio input impedance is high, and therefore must be used active pickups.
Similar to the video input audio transmission requires line to avoid interference, avoid Weld, poor
contact, and special attention to prevent a string of high-voltage current into.
2.6. Audio output
Audio output signal parameters is generally greater than 200mv 1KΩ (BNC), you can directly connect
the low impedance headphones, powered speakers or other sound through power amplifier output
devices. In the case of external speakers and microphone cannot be achieved spatial isolation, it is easy
to produce output howling phenomenon. At this point the measures to be taken are:
1. The use of directional better pickups;
2. Adjust speaker volume, making it lower than the threshold to produce the whistle;
3. Multi-use environment using sound-absorbing materials decoration, reduce the reflection of the
sound, improve the acoustic environment;
4. Adjust the layout of pickups and speakers, but also can reduce the occurrence of howling
situations.
2.7 Alarm input and output connections
Before connecting the device, please note the following:
* Note: Some Series devices without alarm input and output functions.
2.7.1 Alarm Input
Alarm input is grounding alarm input;
Alarm input requirements for ground voltage signal;
When the alarm is connected to two NVRs or simultaneously access the NVR or NVR and other devices,
need to be isolated by relay.
2.7.2 Alarm Output
NVR alarm output cannot be connected power load (no more than 1A), should constitute the output
loop current is too large to prevent damage to the relay. Require the use of high-power load contactors
isolation.
2.7.3 PTZ decoder connected
A. must do PTZ decoder and NVR common ground, otherwise there may be common-mode voltage will
lead to control PTZ. Recommended to use shielded twisted pair with shielding for common ground
connection;
B. prevent high voltage in series, rational layout, good lightning protection measures
C. to be incorporated into the 120 ohm resistor in the remote reduced reflection, to ensure signal quality;
D. NVR 485AB line cannot be connected with other 485 output;
E. AB line voltage between the decoder requires less than 5V.
2.7.4 Front-end device requires grounding

11
Poor grounding may cause the chip to burn.
2.7. Any type of alarm input
The alarm output unit interface is a normally open type.

Chapter 3 Basic operations
Note: Gray button indicates non-support.
3.1 Boot
Plug the power, open the rear panel power switch, power turns on, video recorder starts. Buzzer
beeps after booting .The default video output is multi-screen output mode. When start-up time is within
video setting time, the system will start timer recording automatically , the corresponding channel
recording indicator light turns on, system starts working.
Note:1. Make sure the input voltage corresponds to device power pull-bit switch. Turn on the power
switch after confirming.
2. Power supply demands: 220V±10% /50Hz.
Suggest using the UPS to protect the power supply under allowable conditions, stable voltage value and
less interference power input are recommended.
3.2 Shut down
Soft-switching and hard switching can shut down the device. Soft switch, enter [main menu]> [shut down
system] , Select [shut down]; Hard switch, press the power switch on the rear panel.
Directions:
1、Auto resume after power failure
If the NVR is shut down abnormally, it can automatically backup video and resume previous
working status after re-starting.
2、Replace the HDD
Before replacing, the power supply switch in the real panel must be turned off.
3、Replace the battery
Before replacing, the setting information must be saved and the power supply switch in the real
panel must be turned off. The NVR uses button battery. The system time must be checked regularly.
If the time is not correct you must replace the battery, we recommend replacing the battery every
year and using the same battery type.
Note: The setting information must be saved before replacing the battery otherwise
information will be lost.
3.3 System Login
When the NVR boots up, the user must login and the system provides the corresponding functions
with the user purview. There are three user settings. The names are admin, guest and default and
these names need no password. Admin is the super user purview; guest and default’s permissions are
preview and video playback. User admin and guest’s password can be revised, while their permissions
can’t be revised; user default is the default login user whose permission can be revised but not its
password.

Password protection: If the password is continuous wrong three times, the alarm will start. If
the password is continuous wrong five times, the account will be locked. (Through rebooting or
wait half an hour, the account will be unlocked automatically).
For your system security, please modify your password after first login.
3.4 Preview
After login normally, preview screen will be seen. You can click right mouse to choose the switch
