˖ For installation, please refer to the related national construction standards of your local area.

2.1 Check unpacked DVR
2.1.1 Open the box


When you receive the DVR from the transportation corporation, the first thing you have to do is to check if there is
any apparent damage to the appearance. The protective materials used for the package of the DVR can handle most
accidental clashes during transportation.
Then open the box to check the accessories.
After that you can remove the protective layer of the DVR.
2.1.2 About the front panel and the rear panel
Various key functions on the front panel and various interfaces on the rear panel are introduced in detail in the
instruction book.
Please check the model on the front panel against your purchase contract carefully.
The tag on the rear panel is very important to our after-sales service. Don’ttear it up or discard it (The product
serial number is alwaysrequired when obtaining warranty services).
2.1.3After open the outer cover,you should check:
Besides checking apparent damages, please check whether there is any loose connection between the front panel’s
data ribbon, power cable, the cooling fan’spower line and the mainboard.
2.2 Installation precaution

2.2.1 Install HD
Atthe first installation, makesure that the HDDs are installed properly.
2.2.1.1 How to choose hard disks
High speed HD 7200 rpm or higher is strongly recommended. Westrongly recommend Hitashi/IBM brand
harddrives.
2.2.1.2 How to choose HDD size
1ǃHardDrive Size
For single HD, the user can use harddrive from 10Gabove, but for better stability, 80G-250GHD is recommended.
2ǃHow to calculate the total sizeof HDDs
The computing formula of total HDD sizeis:
The total size(M) = channel numbers *recording hours *HDD used per hour(M/h)
So we can get the computing formula of recording hours:
recording hours= the total size˄M˅
HDD used per hour (M/h)
DVR adopts MPEG4/H.264 compression technology.This technology will produce considerable dynamic range when
compressing data. So when you calculate the total HD size, you should estimate the average HDD sizeper hour per
channel.
For example:
For 4-ch DVR, the average sizeof HDD used per hour per channel is 200M/h. Now if you hope the DVR can record for
30 dayswith 24 hours one day, the total sizeof HDD needed is: 4channels *30 days*24 hours *200 M/h = 576G. So
you need install five120GHDD sor four 160GHDDs.
2.2.1.3HDD installation (see chapter 3for installation diagram)
It is stronglyrecommended that Harddisks are installed by our certified techniciens.
HDD shelf design are already provided in the accessories to benefit you to install HDDs.
One point you should takespecial attention is about HDD jumper wire:
If only one HDD is connected to an IDE port, you should set the HDD to MASTER. If two HDDs are connected to
one IDE port, you must set one as MASTER and the other as SLAVE. Please don’tset HDD as CS Enable or Cap
Limit.
After HDD installation, please check connection of data ribbon and power cord, then mount the outer cover.

2. It is strongly recommend to purchase CD/DVD burner pre-installed.

2.2.3Connection of exterior power supply
Confirm the right position of the toggle switch near the power socket according to the input voltage. 
Werecommend you use stable and less wave interference power supply that will benefit steady operation and
useful time of DVR. It also benefits operations of other peripheral equipments such as cameras. If possible, UPS
power is the best choice.
2.2.4 Install DVR in the machine cabinet
The sizeof DVR is 2Ustandard industrial caseˈ441mm (Wide)x430mm (Deep)x89mm (High)
The sizeof the keyboard is 310mm*160mm*75mm(*88 hand handle)
Put the cabinet in ventilated place. Avoid extreme heat, humid and heave dusty conditions. After long time use, you
should clean inlet opening, cooling fan etc. with asoft dry brush.
2.3 Connection of video/audio input/output
2.3.1 Connection of video input
The video input interface is BNC. The request of video input is PAL/NTSCBNC˄1.0V
P- P
ˈ
75¡˅.
The video signal should comply with national standards. High SNR, low distortion, low interference, natural color
and suitable lightness are also needed for the video signal.
Checkthe stabilityand reliabilityof the camera signal:
The camera should beinstalled at suitable place. Under backlighting, low illumination surroundings that are
not suggested, the user should use backlighting compensation camera or low illumination camera.
The power supply of the camera should have the same grounding with the power supply of the DVR to ensure
the normal operation of the camera.
 Checkthe stabilityand reliabilityof the transmission line


Use high quality, good shielded BNCand choose suitable BNCmodel according to the transmission distance.
Page 14 of 52
Blue Box User Guide

For too long distance, you should use twisted pair, add video compensation devices or use optical fibre
transmission to ensure video quality.
You should keep the video signal away from the strong electromagnetic interference, especially the entry of
high tension current.

Keep connection lugs in well contact:


 The signal line and shielded wire should befirm and in well connection. Avoid dry joint, lap welding and
oxidation.
2.3.2 Audio input
1, 4/8-ch use BNC. 16-ch uses RCA audio cable via a25-pin tieline.
Due to high impedance of audio input, you must use active sound pick-up.
Audio transmission is similar to video transmission. Try to avoid interference, dry joint, loose contact and entry of
high tension current.
2.3.3How to choose and connect video output device
Video output includes a%1&3$/176& %1&˄933ˈ¡˅output and aVGA output
Werecommend you use the industrial monitor as video output device.
The industrial monitor has the following advantages:
1ǃCan adapt industrially long-time monitoring. Ordinary civilian device is easy to age, damage and even
burn under long-time playing.
ǃ Has higher definition and color recover ability that the civilian device is uncomparable. 
ǃ Better stability and anti-interference ability, adapt to various complicated surrounding.
When pc-type monitor is used to replace the monitor, the following points should benoticed:
1ǃTo defer aging, the pc monitor cannot bepowered on for long time
ǃ Regular demagnetization will benefit the monitor to work in normal state.
ǃ Keep away from strong electromagnetic interference devices.
Using TV as video output device is not areliable substitution method. The user also need reduce the hours of use
and control the interference from power supply and other devices. The hidden short circuit problem of low quality
TV may bring damages to other devices.
2.3.4 Audio output
The audio output parameter of DVR is 2000mvp-p1K¡(BNC).Can connect directly with low impedance

earphone, active sound box or amplifier-drive audio output device.
If the sound box and the pick-up cannot beseparated spatially, it is easy to arouse squeaking. Atthis time you can
adopt the following measures:
ǃ Use better sound pick-up with better directing property.
ǃ Reduce the volume of the sound box to the value under which squeaking will not happen.
ǃ Using more sound-absorbing materials in decoration can benefit to reduce voice echo and improve
acoustics environment.
4ǃAdjust the layout to reduce happening of the squeaking.
2.4 Connection of alarminput and output devices
Before connection, please pay attention to the following points:
1. Alarm input
a. First confirm if the alarm input is grounding alarm input or voltage alarm input.
b.Alarm input: Grounding signal is needed for alarm input.
2. Alarm output
The alarm output port should not beconnected to high power load directly to avoid heavy current which will destroy the
relay, but you can use the cocontactor to realizethe 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 possible common mode voltage may fail to control
the PTZ. Shielded twisted wire is recommended and the shielded layer is used to connect to the grounding.
b.Avoid the entry of high voltage. Ensure proper wiring and some thunder protection measures
c. For too long signal wires, 120¡should beparallel 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.
