3 Installation and Connections
Note: All the installation and operations here should conform to your local electric safety rules.
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 detailed information of the function keys in the front panel and the ports in the rear panel, please refer to the appendix for detailed 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 Appendix for recommended HDD brand. Please follow the instructions listed below to install hard disk.
1. Loosen the screws of the

upper cover back.
Note:
You can connect the HDD data cable and the power cable first and then fix the HDD in the device.
Please pay attention to the front cover. It adopts the vertical sliding design. You need to push the clip first and then put down.
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
Please note the following figure is based on the general series product.
3.5.1 Connecting Video Input
The video input interface is BNC. The input video format includes: PAL/NTSC BNC1.0V
P- P
75.
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
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
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 BNC(PAL/NTSC1.0V
P-P
75Ω)output ,a VGA output and HDMI output.
System supports BNC, VGA and HDMI output at the same time. When you are using pc-type monitor to replace the monitor, please pay attention to the following
points:
To defer aging, do not allow the pc monitor to run for a long time.
Regular demagnetization will keep device maintain proper status.
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 RCA port. Due to high impedance of audio input, please use active sound pick-up. Audio transmission is similar to video transmission. Try to avoid interference, dry joint,
loose contact and it shall be away from high tension current.
3.6.2 Audio Output
The audio output signal parameter is usually over 200mv 1K (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:
Use better sound pick-up with better directing property.
Reduce the volume of the sound box.
Using more sound-absorbing materials in decoration can reduce voice echo and
improve acoustics environment.
Adjust the layout to reduce happening of the squeaking.
3.7 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 Figure 3-1. 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.
Figure 3-1
3.8 Other Interfaces
There are still other interfaces on the DVR, such as USB ports.
4 Overview of Navigation and Controls
