Chapter 1. Function of the NVR Server

1.1 Introduction of the Functions

The NVR Server realizes the centralized storage of the surveillance recording files. It gets the

video data stream by connecting the device directly or using stream media server, save these data

in pre-allocated disc spaces in the data block form, and save the recording file information by the

disc‘s data index files. This software has VOD Server inside, and provides the interface for remote

searching, so it is convenient to playback particular recordings remotely.

The NVR Server records particular surveillance videos during the given time sections

according to the plan users have set and realizes the centralized storage. It is used mostly in the

following two cases:

1. The distributed clients run at different places on the network. The NVR Server realizes the

centralized management of the live surveillance video.

2. The NVR Server provides recording service when DVR devices have no HD.

As a part of a network surveillance system, the NVR Server has only a few functions,

focusing on the centralized storage. It mainly has the following functions:

1. Group the partitions. Manage the recording data by disc pre-allocation technology.

2. Support the adjustment of basic running parameters of the Server.

3. Set the recording plan with half an hour as the unit.

4. Provide friendly management interface for the record plan.

5. Have a VOD Server inside. Provide the remote search and VOD function for the recording

data.

6. Support remote operations as setting the record plan, starting or stopping recording

manually.

1.2 Introduction of the Performance

The performance of the Server depends on the performance of the deployed device’s following

- 1 -

User Manual for NVR Server

hardware: the band-width, CPU’s speed, memory’s size, disc’s size, disc’s speed, etc. The Server

operates on the disc frequently; as a result, improving the disc’s performance can improve the

Server’s performance. When it is recording, the operation on the disc may conflict with the virtual

memory operation executed by the operating system, so it is recommended that another partition

shall be used to store the video data. The Server uses many threads; it would be better to choose a

high performance CPU. A big size of memory is good for the Server, too.

When the Server deploys the devices, the running parameters’ limitation should be set

according to the specific hardware. If the Server works unstable, lower the parameters and run

again. If the problem still exists, please contact the developers to ask for advice.

Remote playback restrictions: at most 30 channels playback and 5 channels download at the

same time.

Suggestion: The number of recording channel at the same time is not more than 100; the disc

group number is not more than 5; the partitions every disc group is not more than 10.

1.3 Running environment

The running environment of the Server:

Hardware platform requirements: The current dominating configurations of PC (CPU:

1.5G Hz, 512M Memory, two partitions). Adding any 1TB storing space needs to add about 25

MB memories; adding one recording channel needs to add 2MB memories. Adding a disk group

add 150M memories.

Note: The index files are very big because the Server adopts the disc pre-allocation

technology to store the data. The volume of each partition must be less than 5TB, and no

more than 3TB is recommended; the total size of all the partitions should not exceed 30TB.

Software requirements：Windows 2K/XP/2003; Access 2003

Chapter 2. Instructions for NVR Server

2.1 The Preparations

2.1.1 The Organization of the Discs

The following points on how to organize the discs should be paid attention

to:

1. Because of the disc pre-allocation technology, the store unit is data block, and

writing operation is frequent when recording. So it is recommended that divide the

hard disc into two or more partitions, the partition used to store the video data is

isolated from the partition where the operation system runs.

2. The disc pre-allocation technology reduce the Read\Write head’s wiggle, and cut

down the answering time, so it is recommended that the partitions on the same hard

disc should be put into the same disc group.

3. The disc’s performance has a limitation; in order to lift the Server’s answering

ability, it is recommended that the number of channels that recording at the same

time should be less than 100 in each disc group.

4. The record data is stored circularly in every disc group, when the pre-allocated disc

space is full, the oldest data will be covered with the newest data. If you need to

recording for a long time, please buy discs big enough.

5. SATA HDs are recommended. If using disc matrix to store, whether the IO

performance of the disc matrix can satisfy the demand of frequently writing and

reading should be confirmed.

6. If using the disc matrix to store, the disc matrix should be mapped as the system’s

fixed disc partitions or remote disc partitions.

7. Format the disc partitions that are planned to store the video data into NTFS format,

or else it will take a long time to format when pre-allocation.

8. The symbol of the disc that is assigned to store the record data can’t be changed

- 3 -

User Manual for NVR Server

after being formatted. Another formatting is required if there is a need to change the

disc’s symbol. Violating this rule, serious mistakes will happen in the NVR Server.

2.1.2 Original Database File

The NVR Server uses the Access 2003 database to store the system configuration information,

disc group information, device and channel information, recording plan template, etc. The name of

the Access database is: pdcss.mdb. It is defined inside the system and cannot be changed.

There is a file named “pacss_bak.mdb”, it is the original data base file, user can change its

name to “pdcss.mdb” and use it while the previous one is damaged, however, all the recorded files

cannot be explored and the record plan should be reset.

2.1.3 Confirm the Running Environment

The machine where the software is deployed needs MFC running environment. Generally it can

run on Windows 2000/XP/2003, and does not support others.

2.2 Introduction of Operations on the Server

2.2.1 Running for the First Time

When running for the first time, system will pop up a dialog to tell it and some necessary

configuration must be done before running the server. The following interface will be shown after
