2.5 Installation connections sketch map ( elow just as the 4CH DVR for example,Specifically please
refer to practical product.)
2.6 Audio and video input and output connections
2.6.1 Video input connections
The video input port is BNC connector plug. The demand of input signal is PAL/NTSC BNC(1.0V
P-P
,7 Ω).
The video signal must be accorded with the state standard which has the high signal to noise ratio, low
aberration and low interference. The image must be clear and has natural color in the appropriate brightness.
Insure the camera signal stable and credible
The camera should be installed in the appropriate location where is away from backlighting and low
illumination or adopts the better backlighting and low illumination compensation.
The ground and power supply of the camera and the DVR should be shared and stable.
Insure the transmission line stable and credible
The video transmission line should adopt high quality coaxial pair which is chosen by the transmission
distance. If the transmission distance is too far, it should adopt shielded twisted pair, video compensation

equipment and transmit by fiber to insure the signal quality.
The video signal line should be away from the electro magnetic Interference and other equipments signal
lines. The high voltage current should be avoided especially.
Insure the connection stable and credible
The signal and shield lines should be firm and connected credible which avoid false and joint welding and
oxidation.
2.6.2 Video output connections and options
The video output is divided into PAL/NTSC BNC(1.0V
P-P
,7 Ω) and VGA output(selective configuration).
When replace the monitor by the computer display, there are some issues to notice.
1、Do not stay in the turn-on state for a long time.
2、Keep the computer display normal working by demagnetizing regularly.
3、Stay away from the electro magnetic Interference.
TV is not a credible replacement as a video output. It demands reducing the use time and control the power
supply and the interference introduced by the nearby equipments strictly. The creepage of low quality TV can lead
to the damage of other equipments.
2.6.3 Audio input
Audio port is RCA connection.
The input impedance is high so the tone arm must be active.
The audio signal line should be firm and away from the electro magnetic Interference and connected credible
which avoid false and joint welding and oxidation. The high voltage current should be avoided especially.
2.6.4 Audio output
Commonly the output parameter of DVR audio signal is greater than 200mv 1KΩ(BNC) which can connect
the low impedance earphone and active sound box or other audio output equipments through power amplifier.
If the sound box and the tone arm can not be isolated, howling phenomena is often existed. There are some
methods to deal with the above phenomena.
1、 Adopt better directional tone arm.
2、 Adjust the sound box volume to be under the threshold that produces the howling phenomena.

H.264 Network Digital Video Recorder User Manual

3、 Use fitment materials that absorb the sound to reduce reflection of the sound.
4、 Adjust the layout of the sound box and the tone arm.
2.7 Alarm input and output connections(Some models no such function,please prevail in kind.)

３、
、、
、PTZ decoder connections
A. The grounding of the PTZ decoder and DVR must be shared otherwise the common-mode voltage will
lead to the PTZ control failure. The shielded twisted pair is recommended.
B. Avoid the entrance of high voltage. Make the layout reasonably. Take precaution from the thunder.
C. In the outlying end connect 120Ω resistance paralleled to reduce the inflection and insure the signal
quality.
D. The RS48 +、- lines of DVR can not connected with other RS48 output equipments paralleled.
E. The voltage between the +、- lines of the decoder must be less than V.

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.
2. Power supply demands: 220V±10% / 0Hz-60Hz.
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. Soft-switching：Entering [right menu] and choosing [turn off] in

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 Login
When the DVR boots up, the user must login and the system provides the corresponding functions with the
user purview. There are four user settings. The names are Admin, User ,Guest and Default. Admin default have
no password. Default is default user name when booting up; Admin and User are the super user at the factory
presetting ;Guest is the common user at the factory presetting; Default user’s factory presetting permissions are
preview and playback.
