1. Product Introduction
1-1 Introduction and safety information
Thank you for purchasing DIGISOL NVR!
This user manual is a reference guide for the installation and operation of your NVR. Before
installation and operation please read the following safeguards and warnings carefully!
Important Safeguards and Warnings
Do not place heavy objects on the NVR.
Do not let any solid or liquid fall into or infiltrate the NVR.
Please brush the printed circuit boards, connectors, fans, machine box and so on regularly.
Before the dust cleaning please switch off the power supply and unplug it.
Do not disassemble or repair the NVR yourself.
Do not replace the components yourself.
Environment
Please place and use the NVR between 0ºC and 40ºC. Avoid direct sunlight & keep the NVR
away from heat source.
Do not install the NVR in damp environment.
Do not use the NVR in smoky or dusty environment.
Avoid collision or strong fall.
Please ensure the NVR level installation in a stable workplace.
Please install in ventilated place. Keep the vent clean.
Use within the rating input and output scope.

2. Open-package check and cable connections
2-1 Package Contents
Before you start using this NVR, please check if there’s anything missing in the package, and contact your
dealer of purchase to claim for missing items:
One NVR (8 channel)
Power adapter
Quick Installation Guide
1 USB Mouse
Installation Guide CD
Tools Package (Screws)
2-2 Front panel and rear panel
The key function specifications in the front panel and the interface specifications in the rear
panel are mentioned in Appendix 3.
Please check whether the product type in the front panel is according to the product type
you ordered.
The label in the rear panel is very important for the after service. Please protect it carefully. When
you contact us for after service, please provide the product type and serial number in the label.

2-3 Hard disk installation
The NVR contain 2 SATA HDD. If installing or upgrading, please use a
HDD of 7200rpm or higher which is specially designed for NVR/ DVR applications.
Please follow the instructions mentioned below to installT/upgrade the HDD.

2-6 Audio and video input and output connections
2-6.1 Video output connections and options
The video output is divided into PAL/NTSC VGA output & HDMI output (selective
configuration). When you replace the monitor by the computer display, there are some issues to
notice.
1. Do not stay in the turn-on state for a long time.
2. Keep the computer display normal working by demagnetizing regularly.
3. Stay away from the electromagnetic Interference.
TV is not a credible replacement as a video output. It demands reducing the use time and
control the power supply and the interference introduced by the nearby equipments strictly. The
usage of low quality TV can lead to the damage of other equipments.
2-6.2 Audio signal input
Audio port is BNC connection.
The input impedance is high so the tone arm must be active.
The audio signal line should be firm and away from the electromagnetic Interference and connected
credible which avoid false and joint welding and oxidation. The high voltage current should be
avoided especially.
2-6.1 Audio signal output
Commonly the output parameter of NVR audio signal is greater than 200mv 1KΩ (BNC) which
can connect the low impedance earphone and active sound box or other audio output equipments

through power amplifier. If the sound box and the tone arm cannot be isolated, howling
phenomena is often observed. There are some methods to deal with the above phenomena.
1. Adopt better directional tone arm.
2. Adjust the sound box volume to be under the threshold that produces the howling
phenomena.
3. Use fitment materials that absorb the sound to reduce reflection of the sound.
4. Adjust the layout of the sound box and the tone arm.
3 Basic operation
3-1 Turn on
Plug the adapter and turn ON the power supply switch. Power supply indicator light indicates
turning on the video recorder. After the startup you will hear a beep. The default setting of video
output is multiple-window output mode. If the startup time is within the video setting time, the
timing video recording function will start up automatically. Then the video indicator light of
corresponding channel is ON and the NVR is working normally.
Note: 1. Make sure that the input voltage corresponds with the switch of the NVR power supply.
2. Power supply demands: 220V±10% /50Hz.
We suggest using the UPS to protect the power supply under allowable conditions.
3-2 Turn off
There are two methods to turn off the NVR. Entering [main menu] and choosing [turn off] in the
[Turn off the system] option is called soft switch. Unplug the power adapter to turn off the NVR.
Pressing the power supply switch is called hard switch.
Illumination:
1. Auto resume after power failure
If the NVR is shut down abnormally, it can automatically backup video and resume previous

NVR User Manual

working status after power failure.
2. Replace the hard disk
Before replacing the hard disk, unplug the power adapter to turn off the NVR.
3. Replace the battery
Before replacing the battery, the setting information must be saved. The NVR uses button battery.
The system time must be checked regularly. If the time is not correct you must replace the battery,
we recommend replacing the battery every year using the same battery type.
Note: The setting information must be saved before replacing the battery otherwise information
will be lost.
