3Installation and Connections
Note: All the installation and operations here should conform to your local
electric safety rules.
3.1Check Unpacked DVR
When you receive the DVR from the shipping agency, please check whether there is
any visible damage to the DVR appearance. 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. Finally you
can remove the protective film of the DVR.
3.2HDD Installation
3.2.1 Choose HDDs
We recommend Seagate HDD of 7200rpm or higher.
3.2.2 Calculate HDD Size
This series have no limit to HDD capacity. You can use 120G-750G HDD to
guarantee higher stability.
The formula of total HDD size is:
Total Capacity (MB) = Camera Amount * Recording Hours * HDD Usage Per Hour
(M/h)
H.264 compression is ideal for standalone DVRs. It can save more than 30% HDD
capacity than MPEG4. When you calculate the total HD capacity, you should
estimate the average HDD capacity per hour for each channel.
For example, for a 4-ch DVR, the average capacity of HDD usage per hour per
channel is 200M/h. Now if you hope the DVR can record the video 12 hours each
day for 30 days, the total capacity of HDDs needed is: 4 channels * 30 days * 12
hours * 200 M/h = 288G. So you need to install one 300G HDD or 2 160G HDDs.
3.2.3 HDD Installation
Data ribbons, fastening screws and smart HDD shelf design are already provided in
the accessories.
Notes:
Please pay attention to HDD jumper:
z If you just need to install one HDD, you can set the HDD to MASTER.
z If you install two HDDs to one IDE port, you need to set the farther one as
MASTER and the other as SLAVE. Please don’t set HDD as CS Enable or Cap
Limit.
Please follow the instructions below to install hard disk.

3.3 CD/DVD Burner Installation
For built-in burner, you can dismantle front plate to install CD burner. This built-in
burner should be set as MASTER.
For USB burners, you need to install USB series burner.
This series DVR is compatible with various burner brands popular in today’s market.
You can consult our local technical support or visit our website for more information.
3.4Desktop and Rack Mounting
3.4.1 Desktop Mounting
To prevent surface damage, please make sure that the rubber feet are securely
installed on the four corners of the bottom of the unit.
Position the unit to allow for cable and power cord clearance at the rear of the unit.
Be sure that the air flow around the unit is not obstructed.
3.4.2 Rack Mounting
The DVR occupies two rack units of vertical rack space.
The hardware necessary to mount the DVR into a rack is supplied with the unit.
Rear doors may be used only on rack columns that are more than 26 inches (66.0
cm) deep.
Install the cabinet in ventilated place. Avoid extreme heat, humid or dusty conditions.
You can use a soft dry brush to clean opening outlet, cooling fan and etc regularly.
3.5 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.
3.6 Connecting Video Input and Output Devices
3.6.1 Connecting Video Input
The DVR automatically detects the video standard (PAL or NTSC) whenever you
connect a video input. It accepts both color and black-and-white and analog video.
NOTE:
z Enabling line lock on cameras may cause video distortion. There may be noise in
the camera’s power source. If video from one or more cameras is distorted, we
recommend you disable line lock on the camera as your first troubleshooting step.
z If a video distribution amplifier is installed between the video source and the DVR,
do not set the output video level above 1 Vp-p.
To connect each video input:
1. Connect a coaxial cable to the camera or other analog video source.
2. Connect the coaxial cable to the video in connector on the rear panel.
Please refer to
NOTE:
You need to use a BNC installation tool to connect coaxial cables to the rear panel.
368H368H367HFigure 3-1 for more information.
24
Figure 3-1
3.6.2 Connecting Video Output
This section provides information about physically connecting video display devices
to the DVR. See
369H369H368HFigure 3-2.
If you connect the DVR with a TV monitor or VGA monitor, the DVR can automatically
detects the monitor type. And without any output device, by default, the DVR is
configured to use a TV monitor. In this case, if your application requires a VGA
monitor, you have to press the button “FN” or Shift on the front panel.
NOTE:
Video output 1 and VGA can’t display at the same time. But Video output 2 can
display properly with Video Output 1 or VGA.
For the 25-pin or 37-pin interface, different models include different functions.
For example, DH-DVR1604GBE has 16 audio inputs, 1 audio output, I bidirectional
audio input. See
3.7.1 Audio Input/One Audio Output
DVR1604GBEH has 16 looping video inputs, 1 matrix video outputs, 4 audio inputs, I
bidirectional audio input, 1 audio output.
Audio input, bidirectional audio input and audio output
The DVR encodes audio and video signals simultaneously, which lets you control
audio at the monitored location.
To set up audio:
1. Make sure your audio input device matches the RCA input level. If the device and
RCA input levels do not match, audio distortion problems may occur.
2. Make sure the audio connector is wired as follows:
3. Connect a line input device or pre-amplified microphone to the audio connector for
the video channel on the rear panel.
Please refer to
370H370H369HFigure 3-3.
Figure 3-3
371H371H370HFigure 3-4.
Figure 3-4
26
3.7.2 Looping video
The DVR supports looping video. It passes the video input to a monitor or other
analog video device.
To use looping video:
1. Connect a coaxial cable to the video out connector on 37-pin interface
Please note you need to use a BNC installation tool to connect coaxial cables to the
rear panel.
2. Connect the other end of the coaxial cable to the analog device.
3.7.3 Matrix Video Output
Use video matrix output connector during installation to display video sequentially
from each video input. The unit displays each channel for selected seconds. You can
use this feature to verify camera installation.
To display video from each connected video source:
1. Connect a video monitor to the video matrix output connector.
2. Turn the DVR on, the monitor, and each video matrix output source.
3. Verify the video from each source and troubleshoot as necessary.
Please refer to
372H372H371HFigure 3-5.
Figure 3-5
3.7.4 Alarm Input and Relay Output
The DVR offers 16 alarm inputs for external signaling devices, such as door contacts
or motion detectors. Each alarm input can be either normally open or normally closed.
Once configured, an alarm input can invoke many different activities, including
triggering a relay device, sending an alert to a security office or storing pre-alarm
video to the DVR.
3.7.5 Alarm Input
You should check your alarm input mode is grounding alarm input or not.
For this series DVR, grounding signal is needed for alarm input.
If you need to connect two units or one DVR and other device, please use relay to
separate them.
Please refer to
