New variable $MSE, and Dynamic Print variables on IQeye cameras

An interesting "Dynamic Print" or DP variable was added to the firmware for IQ8xx and IQ7xx cameras a few releases ago.

Dynamic Print variables are those that represent internal, and possibly dynamic, camera values, and can be used in filenames on triggers, inside of image captions, and on custom webpages that you write and upload to the camera.

This particular variable is pretty cool. It is:

$MSE = Milliseconds since epoch

One of the problems I had encountered with IQeye cameras is I was only able to set up rules to name trigger images with granularity to the second. This presents the following sorting problem:

Trigger sequences are supposed to go from negative numbers to positive ones, like trig-03, trig-02,  trig-01,  trig+00,  trig+01  trig+02. However, since the date comes before the trigger sequence number in the filenames, when an event "spans seconds", where the last set of images roll over into the next second, this plays havoc on the sorting.

In addition, there is no guarantee that your filemanager will put trig-03, trig-02,  trig-01,  trig+00,  trig+01  trig+02 in order, even by themselves.

Old

i.e.

File Path "$SH/$SD(%m)-$SD(%d)/$SD(%H)"

File Name "$ST.$FN"

This gives you folders with the camera MAC, with folders then dated by month and day, then folders by the hour, and then the default filenames for the JPEGs themselves.

00_1a_22_21_48/05-19/14/14_10_39.trig-02.jpg

New

i.e.

File Path "$SH/$SD(%m)-$SD(%d)/$SD(%H)"

File Name "$ST.$MSE.$FN"

00_1a_22_21_48/05-19/14/14_10_39.1400510841748.trig-02.jpg

This makes sure that images are sorted in the real order that they were taken.

Maybe other cameras have this variable as well, give it a try!

Other variables

$SH	Your camera’s hardware address.
$SI	Your camera’s IP address.
$SN	Your camera’s name, as specified on the Network Settings page.
$ST	The current time (in 24-hour format: HH:MM:SS, ex: 16:05:20).
$SD	The current date (ex: Wed Feb 03 2010).
$SC	Company name (e.g. IQinVision).
$SP	Product name (e.g. IQeye752).
$SV	The version of operating software on your camera.
$SM	The domain name, as specified on the Network Settings page.
$FN	The name of the file that your camera is accessing.
$MSE	Milliseconds since epoch
$IMGDBG	Image debug data
$O(oidNumber)	Display an OID, like IP address (3.6.10) or the image focus value(1.2.25) or last trigger event time (1.3.20)

For time-based variables, you can use $SD in combination with the common strftime() UNIX time variables. Not all variables work. I may update this post to reflect that.
