Recording tab / Recording settings

The recording settings are configured when recording images from network cameras. If you do not need to record and you only want to view images from network cameras, there is no need to configure the recording settings.

When using Nekaroku, the recording settings for Nekaroku must be configured on the Nekaroku side. Please note that the recording settings on this settings screen (such as checking "Record") and the recording timing settings are recording settings for the video recorder function and are not linked to the recording settings on the Nekaroku side. For details on linking with Nekaroku, please refer to "Linking with Mitsubishi Electric's "Nekaroku"".

In the Recording Settings on the Recording tab, you can select the recorder to which the camera is assigned, set the frame rate and division unit of the recorded video file, the number of days to store, etc.

p_videosetup_0039

To include this camera in the recording list, check "Record."

p_videosetup_0040

■ Recorder selection

There is an important concept of a "recorder" in recording. For more information about the concept of recorders, please refer to "About Recorders and Recorder Terminals" in the Surveillance System Construction Guide.

In the recorder name setting, you register/select the recorder to perform recording. A "recorder" is a concept similar to a group that logically bundles together cameras in the recording process of a video recorder, and in the actual recording process, a PC that performs the process is assigned to each recorder, and the recording process of each camera belonging to the target recorder is performed on that PC. Therefore, a camera that records must belong to one of the recorders.

p_videosetup_0042

Click the Settings button to the right of the recorder name and the Recorder Registration dialog will pop up.

p_videosetup_0092

(Recorder registration dialog)

p_videorecorder_0085

If a recorder is already registered, select the name of the recorder to which the camera you are configuring will belong and click the OK button.

To add a new recorder, click the Add button to register a new recorder. For instructions on how to register a new recorder, see "Recorder Registration" in the Video Recorder Settings.

The settings for the recorder's recording destination, transfer settings, and viewing destination must be carefully configured to suit the actual operation. For ideas about the recorder's recording settings, please refer to the function explanation, "Video recorder system configuration and operation.

■ Setting the file division unit

The recording file will be split into files according to the minutes specified in the file split unit and saved.

p_videosetup_0058

The file will be divided and saved at the specified time (minutes). You can select "1", "5", or "10" from the combo box. You can also edit the value directly.

Furthermore, when viewing a recorded video, the most recent file that is currently being recorded cannot be opened and played.Therefore, please be careful not to set the number of divisions to a too large value (i.e., a long time), as this will result in a long period of time when the content cannot be viewed.

■ Overlay settings

By setting an overlay, you can overlay a lamp shape or any text on the video you are recording.

The text can be any string, and can also include tag values or the date and time of recording.

p_videosetup_0062

Below is an example of the text displayed:

p_prj_0392

In the example on the left, the counter is displayed on the first line and the time on the second line.

In addition, the values of three tags are displayed from the third line onwards.

*Note: The date and time displayed in white at the top of the example on the left is displayed on the video by the network camera's own function and is not an overlay.

Below is an example of the trigger lamp being displayed.

p_prj_0393

In the example on the left, a lamp is displayed in the upper right corner of the video when a trigger occurs.

For example, if you set the event to record between the condition ON-OFF and the period to record 10 seconds before and after the condition occurs, the lamp will only be displayed on the recorded video while the condition ON is true (the lamp will not be displayed for 10 seconds before and after the condition is not true). This function is useful when you want to visually know when the condition was true when playing back and monitoring videos recorded with the event specification.

The trigger lamp function is a function that is designed to record with a lamp display when an event is established during event-specified recording, and should be used in combination with an event condition. If the trigger lamp is enabled without specifying an event condition, the lamp will always be displayed while recording is in progress.

To configure the overlay, click the settings button below.

p_prj_0394

This will display the following settings dialog:

p_prj_0395

The trigger lamp display settings are made in the area shown on the left.

Display the trigger lamp

Check this box to display the trigger lamp. If you check this box, a lamp (circular shape) will be superimposed on the video when the event condition defined in the event specification in the recording settings is detected.

position

Lamp position and size. Specify the left, top, width and height of the rectangular area in which the lamp will be overlaid on the video, as a percentage of the video's display size.

color

Specify the lamp display color in RGB format. Set an easy-to-understand color according to the background and color of the video you are shooting.

Below is an example of setting it to display in red in the upper right corner.

p_prj_0396

(Example of actual display)

p_prj_0393

p_prj_0397

The text display settings are done in the area on the left.

ID	Add an ID to the overlay text. Click the Add button to add an ID. A new ID "label1" will then be automatically assigned. If you add more IDs, they will be added as label2, label3, etc., allowing you to define multiple text display frames. For example, you can display text in multiple display frames, such as displaying the time in the upper left and the tag value in the lower right. If multiple text IDs are registered, you can select the ID to edit from the combo box. Note that overlay settings are registered individually from the recording settings for each camera, and the text ID set here must be set for each camera.
position	Specify the position and size of the text frame. Specify the left, top, width, and height of the frame to overlay the text on the video as a percentage of the video's display size.
Border Color	Specify the border color of the text display frame in RGB format. If you do not want to display the border, there is no need to edit this.
Border Thickness	Specifies the thickness of the border of the text display frame. Specify 0 to hide the border. Specify -1 to fill the inside of the frame with the border color.
Text justification	This is the text alignment setting. Specify left, right or center alignment horizontally, and top, bottom or center alignment vertically.
Text Color	Specify the text display color in RGB format. Set an easy-to-understand color according to the background and color of the video you are shooting.
Font Name	Specify the font for text display. You can only select the font name here; you cannot specify the size. The size is automatically determined by the "Font height" below.
Font Height	Specifies the height of the text display as a percentage of the video display size.
Displayed only when triggered	If you check this check box, text will be displayed when the event conditions defined in the event specification in the recording settings are detected, in the same way that a trigger lamp is displayed.

You can directly edit the text display format in the edit box at the bottom of the settings dialog.

p_prj_0401

The string entered here will be displayed as text. You can also break the text and display it on multiple lines.

Using the buttons at the top of the edit box, you can embed the following information at the cursor position (formatting enclosed in curly brackets {} as shown below will be replaced and displayed at runtime).

p_prj_0400

Click the Add Counter button and add the format {} to display the counter value.

The counter starts at 0 and increments by one every frame.

p_prj_0398

Clicking the Add Tag button will display the tag selection dialog.

The tag selected in the dialog is added to the cursor position in the tag display format {tag path}. By defining it in this way, you can display the tag value embedded in the text.

p_prj_0399

Clicking the Add Current Time button will add the format {} for displaying the current time.

Below is an example of a text definition that displays the time, counter, and tag. In this example, the text is displayed in red.

p_prj_0402

When executed, text such as "Time:" and "TAG01:" will be displayed as is, and you will see that the tag path and datetime embedded above are dynamically replaced and displayed.

(Example of actual display)

p_prj_0392

■ Maintenance settings

Maintenance settings are related to the automatic deletion of video files.

p_videosetup_0059

This setting can be selected from the following:

Do not automatically delete	No automatic deletion will be performed.
Automatic deletion	Files older than the number of days specified in the retention period will be automatically deleted. If the recording file transfer setting is enabled, the video files at the transfer destination will also be automatically deleted.
Automatically delete (excluding forwarding destinations)	Files older than the number of days specified in the retention period will be automatically deleted. If the recording file transfer setting is enabled, the video files at the transfer destination will not be deleted.

■ Output file frame rate setting

The output file frame rate setting determines the frame rate of the video you want to record (fps.Frames per second).

For example, 1fps means one frame will be recorded per second.

p_videosetup_0060

The minimum value that can be specified for recording fps is "0.5". If a value smaller than that is set, recording will be at 0.5 fps.

Please adjust the value specified for the recording fps based on the allowable file size and the performance of the camera itself (frame rate, etc.). For example, if the camera's playback frame rate is 1 fps (once per second), specifying a large value such as 25 for the frame rate will result in the file size becoming unnecessarily large by simply saving the same image repeatedly.
