3Installation 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 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.
Check the items in accordance with the list. Finally you can remove the protective film of the DVR.
3.2 About Front Panel and Rear Panel
The model label in the front panel is very important; 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
You can refer to the Appendix for recommended HDD brand. Use HDD of 7200rpm or higher.
Follow the instructions below to install hard disk.
All the figurers listed below are for reference only. Slight difference may be found on the
front or rear panel.
3.3.1 Maxi Security Kit PRO FullHD1080P TX-50

3.Place the HDD in accordance with
the four holes in the bottom.
4. Turn the device upside down
and then turn the screws in
firmly. 

Important: You can connect the HDD data cable and the power cable first and then fix the
HDD in the device. 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
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（1.0VBP-
P ，B75Ω.）
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 lineBTTTB
Use high quality, sound shielded BNC. 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 contactBTTTB
The signal line and shielded wire should be fixed firmly and in well connection. Avoid dry joint, lap
welding and oxidation.BTTTB
7. Put the cover in accordance
with the clip and then place the
upper cover back. 
8. Secure the screws in the
rear panel and the side panel. 

19
3.5.2 Connecting Video Output
Video output includes a BNC(PAL/NTSC1.0VP-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, 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 audio input port adopt BNC port. Due to high impedance of audio input,
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 1KΩ(BNC or RCA). 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 Alarm Input and Output Connection
Read the followings before connecting.
1. Alarm input
a. Make sure alarm input mode is grounding alarm input.
b. Grounding signal is needed for alarm input.
c. Alarm input needs the low level voltage signal.
d. Alarm input mode can be either NC (normal Open) or NO (Normal Close)
e. When you are connecting two DVRs or you are connecting one DVR and one other device, 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. 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, 120Ωshould 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. Make sure the front-end device has soundly earthed.
Improper grounding may result in chip damage.
3.7.1 Alarm Output Port
Provide external power to external alarm device.
To avoid overloading, read the following relay parameters sheet carefully.
RS485 A/B cable is for the A/B cable of the PTZ decoder.
T+,T‐,R+,R‐are four-wire double duplex RS485 port. 
T+ T-: output wire, R+ R-: input wire
