Video snapshot

Captured Channel

Select the channel to capture.

JPG file number

In the [System Settings], select [Display Unit] and click the [Mode] tab. From [Screen Capture], select the [Capture Action] check box. For [Save in], when you select [FTP Server] option, this setting is disabled. In this case, the file number becomes a time stamp (year, month, day, hours, minutes, seconds).

Direct

Set a number to be the JPEG file name. The setting range is from 0 to 65535.

The saved file name is "CPXXXXX.JPG" (XXXXX is the specified value). The file will be stored in the "CAPTURE" folder in the CF or SD Card.

  • The file is always saved using the file name defined here. If a file with the same name already exists in the destination, that file will be overwritten.

Indirect

Stores the file number to: [Video Control Address] + 2 specified in the system settings [Image Unit] settings.

  • For any destination other than the FTP server, you can add and delete file numbers by using the [Auto Increment File Number] option, available from the [System Settings], [Display Unit], in the [Mode] tab's [Screen Capture] area.
