Introduction
What is NVR?
NVR stands for Network Video Recorder. NVR is a collection of hardware and software components that
enables full digital, live, and recorded video surveillance over the Internet or Local Network from any
connected computer.
NVR consists of three major components:
NVR device – is an intelligent storage and authentication server.
In theory it can have unlimited number of IP-video/audio suppliers (such as
IP-cameras, Digital Video Recorders, or IP-Servers) logically attached to it.
Any device that is attached could be used by NVR. Video/audio source or
source of the remote event (motion events or remote I/O port event) are
examples of attached devices.
NVR is also an authentication server for the workstations with Remote NVR Client.
Remote NVR Client – a software that can be used to see live video/audio, control
cameras, search archive database and playback the archive.
IP-Video Device – supplies video/audio to the rest of the system.
NVR device structure (in full configuration):
NVR Services
-Authentication Server - Authenticates remote users connected to NVR through
the Remote Client or Archive Viewer
-Creates statistics about the remote users connections
-Recorder - Writes information from each video input in to the
video archive according to the schedule
-FTP Server - Receives FTP-streams from cameras (if set) and writes
information in to the video archive
-Raises an alarm when it receives an alarm sequence
from camera
-Touring module - Moves the camera according to the tour schedule
-Remote I/O Listener (Click
on “Start Test”, and the “Port
Test” window will appear
(Fig. a.).
-Monitors remote inputs on I/O block of the camera
-The main purpose are to test for correct Hardware and
Software settings
-Port test provides information about the camera that is
sending data (Data could be just the connection signal
or the signal about any alarm events.) Fig. b.
-Check Alive module - Checks to see if camera is online and video inputs are
active
-Check Drive Module (It is
used for testing purposes)
Fig. c.
-Checks to see if there is enough space for the NVR
Video archive
-Also checks the Archive Storage Path
-Alarm Central - Responsible for raising alarm using:
-Voice
-Phone (analog line with voice modem
installed)
-E-mail (Note: Sender name must be put in
double quote).

IP-Video Device:
IP-Cameras
-Axis IP-Cameras
-SONY IP-Cameras
-JVC IP-Cameras
-ELMO IP-Cameras
-IDVIEW IP-Cameras
IP-Servers
-Axis IP-Servers
Digital Video Recorders
-EDR400
-ERNITEC (DigiOp)
NVR Network consists of several NVRs that are logically attached to the main NVR (NVR Domain
Controller). Thus, it is possible to control every NVR remotely from the domain controller.
NVR services can be managed from the “Control Panel” by choosing “Administrative Tool” window and
selecting “Services” from the pull down menu (Fig. 1.)
Fig. 1. Services
As it is depicted on Fig .1., NVR Start Bar service has automatic Startup Type.
In this case NVR activates as soon as computer is on, even before the login.
Since NVR StartBar runs as a service, it also starts/stops all other NVR components as services.

The following is a list of Archive storage contents:
9Path
9Keep information for (days)
Controls the duration in which the information is kept in the archive.
The space required for the archive, and the number of frames per second, which will be
received from all cameras in the network, should be calculated according to the
user’s requirements.
9If free space less than (stop saving/overwrite)
The user has the opportunity to choose the time in which, overwrite of the data should take place.
The example presented in Fig. 2 shows a retention rate of 20 days. When drive space falls
to 3 GB free (3000 meg.), program overwrites the oldest data.
9Use Temporary space

1.e. FTP Server
FTP Server receives ftp-sequences from the cameras (AXIS, JVC and SONY cameras only). For JVC and
SONY cameras, ftp-sequence is treated as an alarm sequence.
FTP-client settings must be setup inside the cameras in conjunction with FTP Server settings.
In order for the FTP Server to work properly one needs to setup the path in the “Images path for FTP
Server” field for each camera (see cameras, Fig. 11.). The path for each camera server (or camera) must be
unique and created before the setup can proceed.
Server must be configured after the installation.
User setup must be done after the server configuration (Fig. 8.).
Note: User must define “Root Directory”; this implies the creation of Root Directory on hard drive.
Fig. 8. NVR Setup→General→FTP Server
Home directory could be the absolute or the relative path.
If Home directory is the absolute path, the destination directory will be
Home directory + Directory inside the Camera
If Home directory is the relative path, the destination directory will be
Server Root directory + Home directory + Directory inside the Camera
Destination path must be in the path field of the “Images path for FTP Server” field (see cameras, Fig. 9.
shown later in document).
FTP Server could be started when cameras database is not empty (refer to section 2 of this document), Root
Directory is defined, and setting is completed (Fig. 9.).

NVR

Fig. 9. NVR FTP Server dialogue box
To setup FTP-clients inside the cameras, see the camera manual.
NVR software has special needs for the “image file name” format settings. Some of which are as follows:
-SONY cameras: “image file name” must have name “asony” with the suffix “Date/Time”.
-JVC cameras: “image file name” must have name “alarm_jvc”.
-AXIS cameras: for continuous uploading “base file name” must be “cam1_image” or “cam2_
image” or “cam3_ image” or “cam4_ image” with “Date/Time Suffix“ selected.
-AXIS cameras: for uploading in case of alarm “base file name” must be “alarm_cam1”,
“alarm_cam2”, “alarm_cam3”, or “alarm_cam4”.
To stop the FTP Server, select “Exit” from the menu (Fig. 9.).

NVR

1.f. Advanced
By clicking on the “Advanced” tab in the GENERAL window, you will be able to see various log files that
are generated during the NVR’s operation (Fig. 10.).
There are two kinds of log files available: Server logs, and Alarm logs.
SERVER LOGS are: TRACE, ERRORS, and DEBUG
ALARM LOGS are: NETWORK and PHONE, and EMAIL
Alarm logs are of important values, particularly in event documentation. For instance, when NVR is used in
a monitoring center, the occurrence of an event is kept in the Alarm logs; this in turn can be useful as
evidence for further investigations about that particular event.
Proxy Settings panel
If a company uses web-proxy server that requires authentication to get to the Internet, proxy setting must be
done in this panel.
Get current button helps to get the following information:
•Current domain name
•Computer name
•Current user name
