2.6 Audio & Video input and output connections
2.6.1 video input
DVR 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
color, 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 DVR 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, fiber 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;
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 neighboring
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.
2.6.5 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 DVRs or simultaneously access the DVR or DVR
and other devices, need to be isolated by relay.
2.7.2 Alarm Output
DVR 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 DVR 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. DVR 485 AB 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
Poor grounding may cause the chip to burn.
2.7.5 Any type of alarm input
The alarm output unit interface is a normally open type.

3.Basic Operations
Note: The button is grayed means did not support.
3.1 Turn on
Plug the power supply and turn on the power supply switch. Power supply indicator light
shining indicates turning on the video recorder. After the startup you will hear a beep. The
default setting of video output is multiple-window output mode. If the startup time is within
the video setting time, the timing video recording function will start up automatically. Then
the video indicator light of corresponding channel is shining and the DVR is working
normally.
Note:
1. Make sure that the input voltage corresponds with the switch of the DVR power supply.
Power supply demands: 220V±10% /50Hz.
Suggest using the UPS to protect the power supply under allowable conditions.
3.2 Turn off
There are two methods to turn off the DVR. Right click mouse to get a desktop shortcut
menu ,then choose Logout option is called soft switch. Pressing the power supply switch is
called hard switch.
Illumination:
1、Auto resume after power failure
If the DVR is shut down abnormally, it can automatically backup video and resume previous
working status after power failure.
2、Replace the hard disk
Before replacing the hard disk, the power supply switch in the real panel must be turned off.
3、Replace the battery
Before replacing the battery, the setting information must be saved and the power supply
switch in the real panel must be turned off. The DVR 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 lose.
3.3 System Login
When the DVR boots up, the user must login and the system provides the corresponding
functions with the user purview. There are two user settings. The names are admin, and
default and these names have no password. Admin is the super user purview; default’s

permissions are preview and video playback. User 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.
Figure 3.1 Login
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
reboot or after half an hour, the account will be unlocked automatically).
For your system security, please modify your password after first login.
3.4 Preview
You can right click mouse to choose the switch between the windows.
