System configuration and setting examples for high-quality recording

This section explains the system configuration and setting examples for high-quality recording with a video recorder.

For high quality recording, we will adjust the network camera and recording settings fps value according to the purpose based on the concept of the recommended system configuration. Note that high quality recording is assumed to be recorded at a resolution of SVGA and a frame rate of about 20 fps.

Key points of this configuration

•When recording at a high frame rate, the server PC and recorder terminal PC should be configured as separate PCs.

•A NAS drive is used as the destination for transferring and viewing recorded data.

•In this configuration, the maximum number of cameras that can be connected simultaneously is three.

Expected specifications

item	Setting values etc.	supplement
Video Compression Method	MJPEG	Connection is also possible with "H.264".
Camera Image Resolution	SVGA (800*600)	Set on the camera.
Camera quality	usually	Set on the camera.
Camera Frame Rate	24fps	Set on the camera. If your camera only allows you to select from a set of preset values, select the frame rate that meets your requirements (up to 30 fps).
Recording Frame Rate	20fps	Set from the recording settings when registering the camera.
Number of cameras connected simultaneously	Up to 3 devices	If you want to record in high quality with more than the number of devices listed above, you can do so by distributing the recorder terminal PCs. Alternatively, you can increase the number of devices by lowering the quality of the recording.

If you want to record high quality with more than three cameras, please consider distributing the recorder terminal PC. For details on the distributed configuration, please refer to "When connecting multiple cameras simultaneously (distributed recorder)". Also, if you want to connect multiple cameras and record by lowering the camera's fps, please refer to the description of "When connecting multiple cameras simultaneously (low fps recording)".

Components

explanation

Server PC

(Panel Server)

The server PC will be configured to run only Panel Server.

Recorder terminal PC

(Panel Browser)

Prepare a dedicated PC for the recorder terminal. On this PC, run only the video recorder in Panel Browser and do not display other functions (graphic screen, alarm monitoring, trend graph, etc.).

setting	explanation
Local Disk	Create a folder for recording directly under the local disk of the PC you want to record on. In this example, we will use the "C:\videorecorder" folder.
NAS Drive	Set up the NAS drive so that it can be connected via network sharing, and create a folder to which the recording data will be transferred. In this example, we will use the "G:\videorecorder" folder.
Recorder registration settings	When registering the recorder, set the recording destination to the local disk, transfer to the NAS drive, and view destination to the NAS drive.
Camera registration/frame rate	Set the recording frame rate to "20" fps.
Camera registration/file division unit	The recording file will be divided into 5 minute increments.
Automatic Maintenance	The number of days for automatic deletion (the number of days for which data is saved) should be determined based on the period for which you actually want to save the data and the amount of disk space available. For an estimate of the size of recorded data, please refer to "Recorded Data File Size and Disk Space".

Please pay attention to the number of client licenses. A client license is also consumed for the Panel Browser running on the recorder terminal PC.

Client PC

(Panel Browser)

The client PC that displays the graphic screen, etc., is prepared separately from the recorder terminal PC. Graphic screen and other function screen display (trend, etc.) and viewing/playback of recorded data are performed on the client PC. Note that multiple client PCs can be configured.

If you have multiple client PCs, pay attention to the number of client licenses. You need as many client licenses as the number of Panel Browsers you want to run simultaneously.

Storage for recorded data (e.g. NAS)

Use NAS as the destination for transferring recording data.

Selection points:

❖Please select a model with a fast disk rotation speed (7,200 rpm or higher) and a fast network connection speed (minimum 100BASE or higher).

❖The amount of data required for NAS varies depending on the number of cameras, storage period, recording fps setting, data resolution on the camera side, etc. In addition, "Recording data file size and disk capacity" lists the reference value of the size of the generated recording data.

❖If you would like to make the recording data redundant with this configuration, please set it up yourself using NAS functions (such as RAID).

Network Camera

Below is an example of camera body settings. For details on tuning the camera body, please refer to "About camera body settings and tuning".

setting	explanation
Video Compression Method	If you can choose the compression method, we recommend using "MJPEG".
Frame rate	Set the frame rate of the camera to around "24" fps. If you can only choose from a fixed list, choose one close to it (e.g. "30" fps).
resolution	Keep it at around SVGA (800*600). The higher the resolution, the greater the processing load and data size.
image quality	Please select the image quality that suits your purpose. Try the "Normal" level and tune it according to the situation. The higher the image quality, the larger the processing load and data size will be.

Network Devices

The network equipment for connecting to the network camera should be configured so that bottlenecks do not occur. For example, even if you select high-spec models for the LAN port of the recorder terminal PC or NAS device, if the relay device such as HUB is slow, it will become a bottleneck. Also, if the communication load with the network camera is high, consider preparing multiple LAN ports and HUBs for the PC and configuring the route of the normal network and the network connected to the camera separately.

When communicating with a network camera, the network load may become high depending on the settings of the camera itself (such as the fps value and resolution of the camera itself), the number of cameras connected, etc. Therefore, please select a LAN port with as fast a communication speed as possible for the communication connection with the camera.

Points to note about this configuration

Important points to note

explanation

How many cameras can be connected at the same time?

When recording at high fps like in this configuration, the number of cameras that can be connected simultaneously is limited to about "3". If more than that number of cameras are connected and recorded simultaneously, the processing load will be high and problems such as skipping frames in the recorded data may occur.

Simultaneous playback of recorded data

Playing back data recorded at a high fps places a high load on the CPU. When playing back multiple files recorded at 20 fps at the same time, the maximum number of files that can be played back at the same time is two. For an estimate of the number of files that can be played back at the same time, please refer to "Number of files that can be played back at the same time".

Users must make the recording data redundant themselves.

If you wish to make the recording data transferred to NAS redundant, you must create the system yourself (for example, use NAS to create a RAID configuration, or create a backup system to a separate drive). For details on using the video recorder function in a server duplex configuration, please refer to the description in "When operating a server in a duplex configuration".
