3.1 Check Unpacked DVR

When you receive the DVR from the forwarding agent, please check whether there is any visible

damage. The protective materials used for the package of the DVR can protect most accidental

clashes during transportation. Then you can open the box to check the accessories.

Please check the items in accordance with the list on the warranty card (Remote control is

optional). Finally you can remove the protective film of the DVR.

Note

Remote control is not a standard accessory and it is not included in the accessory bag.

3.2 About Front Panel and Real Panel

For detail information of the function keys in the front panel and the ports in the rear panel,

please refer to the appendix for detail information.

The model in the front panel is very important; please check according to your purchase order.

The label in the rear panel is very important too. Usually we need you to represent the serial

number when we provide the service after sales.

3.3 HDD Installation

This series DVR has only one SATA HDD. Please use HDD of 7200rpm or higher.

You can refer to the User’s Manual for recommended HDD brand.

Please follow the instructions below to install hard disk.

1. Loosen the screws of the

er cover.

2. Remove upper cover.

3. Turn four screws for three rounds to fix HDD bracket.

4. Place the HDD in

accordance with the four holes.

5. Turn the device upside down

and then turn the screw in firmly.

6. Fix the HDD firmly.

7. Connect the HDD cable and

power cable.

8. Place the upper cover back

and screw firmly.

After completing HDD installation, please check connection of data ribbon and power cord.

3.4 Connecting Power Supply

Please check input voltage and device power button match or not.

We recommend you use UPS to guarantee steady operation, DVR life span, and other peripheral

equipments operation such as cameras.

3.5 Connecting Video Input and Output Devices

3.5.1 Connecting Video Input

The video input interface is BNC. The input video format includes: PAL/NTSC BNC（1.0VB

B75Ω. See X283H283H283H287HFigure 3-1.X

The video signal should comply with your national standards.

The input video signal shall have high SNR, low distortion; low interference, natural color and

suitable lightness.

Guarantee the stability and reliability of the camera signal:

The camera shall be installed in a cool, dry place away from direct sunlight, inflammable,

explosive substances and etc.

The camera and the DVR should have the same grounding to ensure the normal operation of the

camera.

Guarantee stability and reliability of the transmission line

BTTTB

Please use high quality, sound shielded BNC. Please select suitable BNC model according to the

transmission distance.

If the distance is too long, you should use twisted pair cable, and you can add video

compensation devices or use optical fiber to ensure video quality.

You should keep the video signal away from the strong electromagnetic interference, especially

the high tension current.

Keep connection lugs in well contact

BTTTB

The signal line and shielded wire should be fixed firmly and in well connection. Avoid dry joint,

lap welding and oxidation.

3.5.2 Connecting Video Output

Video output includes a TBNC(PAL/NTSC BNC（1.0VP- P， 75Ω）output and a VGA output.

System supports BNC, VGA and HDMI output at the same time. See

X284H284H284H288HFigure 3-2X.

When you are using pc-type monitor to replace the monitor, please pay attention to the following

points:

z To defer aging, do not allow the pc monitor to run for a long time.

z Regular demagnetization will keep device maintain proper status.

z Keep it away from strong electromagnetic interference devices.

Using TV as video output device is not a reliable substitution method. You also need to reduce

the working hour and control the interference from power supply and other devices. The low

quality TV may result in device damage.

3.6 Connecting Audio Input & Output, Bidirectional Audio

3.6.1 Audio Input

These series products adopt BNC port.

Due to high impedance of audio input, please use active sound pick-up. See

Audio transmission is similar to video transmission. Try to avoid interference, dry joint, loose

contact and it shall be away from high tension current.

X285H285H285H289HFigure 3-4X.

Figure 3-3

3.6.2 Audio Output

The audio output signal parameter is usually over 200mv 1KΩ (BNC). It can directly connect to

low impedance earphone, active sound box or amplifier-drive audio output device.

If the sound box and the pick-up cannot be separated spatially, it is easy to arouse squeaking. In

this case you can adopt the following measures:

z Use better sound pick-up with better directing property.

z Reduce the volume of the sound box.

z Using more sound-absorbing materials in decoration can reduce voice echo and improve

acoustics environment.

z Adjust the layout to reduce happening of the squeaking.

Please refer to

X286H286H286H290HFigure 3-4X.

Figure 3-4

3.7 Alarm Input and Output Connection

Please refer to the following sheet for alarm input and output connection. See X287H287H287H291HFigure 3-5.X

Figure 3-5

There are two alarm input types for you to select: normal open (NO) and normal close (NC).

1. Alarm input

a. Please make sure alarm input mode is grounding alarm input.

b. Grounding signal is needed for alarm input.

c. When you are connecting two DVRs or you are connecting one DVR and one other device,

please use a relay to separate them,

2. Alarm output

The alarm output port should not be connected to high power load directly (It shall be less than

1A) to avoid high current which may result in relay damage. Please use the co contactor to

realize the connection between the alarm output port and the load.

3. How to connect PTZ decoder

a. Ensure the decoder has the same grounding with DVR, otherwise you may not control the PTZ.

Shielded twisted wire is recommended and the shielded layer is used to connect to the grounding.

b. Avoid high voltage. Ensure proper wiring and some thunder protection measures. c. For too long signal wires, 120Ω should be parallel connected between A, B lines on the far end

to reduce reflection and guarantee the signal quality.

d. “485 A, B” of DVR cannot parallel connect with “485 port” of other device.

e. The voltage between of A,B lines of the decoder should be less than 5v.

4. Please make sure the front-end device has soundly earthed.

Improper grounding may result in chip damage.

3.8 RS232

You can connect the DVR with POS or Keyboard through RS232.

With POS system, the DVR can communicate through RS232 and network. For the POS system, the

DVR can integrate the text content and even search the record through the info.

The series DVR also support NKB operation. You can operate the DVR from the keyboard controls

instead of using the control pad on the front panel of the unit.

To connect a NKB keyboard to the DVR:

1. Assemble the KBD keyboard according to the instructions in its accompanying installation manual.

2. Connect the KBD keyboard into one of the RS232 ports on the DVR or through network.

3.9 RS485

When the DVR receives a camera control command, it transmits that command up the coaxial cable

to the PTZ device. RS485 is a single-direction protocol; the PTZ device can’t return any data to the

unit. To enable the operation, connect the PTZ device to the RS485 (A,B) input on the DVR. See

X289H289H289H293HFigure 3-8X.

Since RS485 is disabled by default for each camera, you must enable the PTZ settings first. This

series DVRs support multiple protocols such as Pelco-D, Pelco-P.

To connect PTZ devices to the DVR:

1. Connect RS485 A,B on the DVR rear panel.

2. Connect the other end of the cable to the proper pins in the connector on the camera.

3. Please follow the instructions to configure a camera to enable each PTZ device on the DVR.
