JPEG FTP Configuration

The following fields determine how the JPEG images are handled with respect to an FTP server.

Transfer Mode	• Archive – Default mode. Each image is saved as a separate
	file up to the value in Max Number of Files on Server. After
	the maximum, the files begin to overwrite.
	• Single Image – Only one image is saved and overwritten on
	the server.
IP Address or Name of	IP address or machine name of FTP server. Default = blank.
Server
File Name on Server	Archive mode – This is the base file name to which incremental
	numbers are appended. If the base file name is VBrick1- for
	example, the captured images will be named VBrick1-1,
	VBrick1-2, and so on.
	Single Image – A .jpg extension will be appended to the base
	file name. Default = blank.
Max Number of Files on	1–1000000. The maximum number of files that will be saved on
Server	the FTP server. Default = 200.
Path on Server	Folder name where images are saved on FTP server. Default =
	root.
FTP User Name	FTP user name. Default = UserName.
FTP Password	FTP password. Default = UserPassword (hidden).
FTP Account	FTP server account login. Default = AccountName.
Max FTP Duration	1–60 seconds. Default = 60. After a server interruption, the
	time to wait before closing the connection and trying again.

JPEG Capture Constraints

Due to memory requirements, JPEG capture can reduce the maximum number of supported clients a dual WM encoder (with archiver), or dual WM and MPEG-2 encoder (with archiver) can support. The following table shows how the configuration for JPEG capture affects the maximum number of supported clients. Also be aware that JPEG capture on a WM encoder will consume significant CPU resources. This can degrade the streaming video—especially with higher video resolutions and frequent image captures.
