2.5 Installation connections sketch map (16CH DVR as an example the following, please
prevail in kind).
Picture 2.1 Installation connections sketch map
2.6 Audio and video input and output connections
2.6.1 Video input connections
A. Analogue video signal: The video input port is BNC connector plug. The demand of input signal
is PAL/NTSC BNC (1.0VP-P, 75Ω).
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.
B. Network HD video signal: The network HD video input port is RJ45 port, this signal comes from
other network video device (such as IPC or other DVR). And it needs to be configured in Mode shift and
Number channel item.
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

H.264 Super Digital Video Recorder User Manual
12
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 device selection and connection
The video output is divided into PAL/NTSC BNC (1.0VP-P, 7 5 Ω) and VGA output(selective
configuration).And HDMI output( HDMI is optional).
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.
2.6.3 The audio signal input
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 creep age of
low quality TV can lead to the damage of other equipments.
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
1、
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.
2、
Adopt better directional tone arm.
3、
Adjust the sound box volume to be under the threshold that produces the howling phenomena.
4、
Use fitment materials that absorb the sound to reduce reflection of the sound.
2.7 Alarm input and output connections (Some models without this function, please prevail
in kind)
Adjust the layout of the sound box and the tone arm.
Please note the following:
１、Alarm input
A. Alarm input is grounding alarm input.
B. Alarm input demand is the grounding voltage signal.
C. When the alarm is connected with two DVRs or connected with DVR and other equipments, it

H.264 Super Digital Video Recorder User Manual
13
should be isolated by relay.
２、Alarm output
Alarm output cannot be connected with high-power load (no more than 1A).When forming the output
loop it must prevent the big current from relay damage. Use the contact isolator when there is a
high-power load.
3、Front equipment grounding note
Bad grounding can lead to the burnout of the chip.
4、Alarm input type unlimited
The DVR alarm output port is constant opening type.
2.7.1 Alarm Input port explain
The grounding and the com port of the alarm sensor are parallel (The alarm sensor is external power
supply).
The grounding of the alarm and the DVR should be shared.
The NC port of the alarm sensor must be connected with the DVR alarm input port.
The grounding of the power supply and the alarm sensor must be shared when used in external
power supply.
2.7.2 Alarm Output port explain
Switch alarm output (normally open contact), external alarm device requires a power supply.
In order to avoid voltage overload and damage the host, attached please refer to relay parameter list,
see table 2.2.

2.8 PTZ Decoder, The ball machine connection
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 120Ωresistance paralleled to reduce the inflection and insure the
signal quality.
D、The RS485 +、- lines of DVR can not connected with other RS485 output equipments paralleled.
E、The voltage between the +、- lines of the decoder must be less than 5V.
F、Connect the 485 lines of the speed dome with the DVR 485 interface.
G、Connect the speed dome video cable with the DVR video input.
3. Basic operation
3.1 Starting up
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% /50Hz-60Hz.
Suggest using the UPS to protect the power supply under allowable conditions.
3.2 Shutdown
There are two methods to turn off the DVR. Soft-switching：Entering “desktop shortcut menu” and
choosing “logout” in the “shutdown” option; Hard-switching：Press the power button on the front panel
or rear panel power switch can switch power.
Notice:
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

H.264 Super Digital Video Recorder User Manual
15
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
