3.4.1.1 Options
The valid parameters for bufferd are:
Option Description
-start
Start a buffer.
-reset
Remove a buffer.
-stop
Stop a buffer.
-d
Start as a daemon. This option should only be used when starting up from
initd, or when the first instance is to be started.
-buffername
<buffername>
The name of the buffer on which the options -start, -stop and -
reset
should act. bufferd will create a directory in /tmp named
<buffername>, in which the images will be stored.
-uri
<request-
string>
The request-uri. Specification of the image-format as described in the
HTTP-API specification (pdf-document). The protocol should be FTP
instead of HTTP. This document can be found on www.axis.com, on the
Camera & Video developer pages.
-postdelay
<delay>
Delay between images in milliseconds.
-predelay
<delay>
Same as –postdelay, but sets an additional variable.
-pre <number>
Number of pre-alarm images, i.e. number of images to save before
stopping the buffer.
-post
<number>
Number of post-alarm images, i.e. the number of images to save after
stopping the buffer.
-format
<format-
string>
Naming convention for the files.
-snapshot
Take one picture.
-immediate
Stops the buffer without waiting for it to complete. Only used in
conjunction with
–stop.
3.4.1.2 Default Values & Settings
If the option -buffername is omitted, the buffer used defaults to buffer (/tmp/buffer).
The protocol specification in the request-uri should be ftp, and not http, as this does not
generate http-specific headers.
The default delays (
postdelay and predelay) are one(1) second (1000 milliseconds).
The default number of images before and after an alarm (pre and post) is 10.
The format-option specifies how the files are named.
Character expansion is supported with:
• %y (year)
• %m (month)
• %d (date)
• %H (hour)
