Web display of picture with changing filename

[yelloow7t]

Greetings,

For a number of reasons, I now have a system running that takes snapshots of cctv cameras at frequent intervals. Each camera saves the snapshots to it's own folder, and the filename is a timestamped name.

Now what I want to do is display the LAST (newest) snapshot on a web page for that camera. Each page refresh would cause the newest snapshot to display.

I either need a way for html (or something) to display the latest file, or automated software to copy the file name to a standard name (no timestamp).

I want to keep the original timestamped files for future time lapse construction.

Any advice would be greatly appreciated.

Tom

you can use geturl in a script and filter the imagename out of it.

If you can modify the image saving software, tell it to also save the picture in a file named camera1.jpg. Then on your web page simply call up the camera1.jpg image. It will always be the most recent picture.

I am only allowed one address to save the file, currently using it to save the time stamped version. Simplest would be for HTML to display the last image, but I cant find anything like that...

Tom,

Could you post an example of the time stamped file?

Does this directory gradually fill up with more and more images over time or is this just a single file?

[yelloow7t]

Jon,

Yes the directory(s) fill with pictures. Here is an example. The filename before uploading was: Camera 2 3-14-2008 10.20.58 AM 11.jpg

Is the time stamp on the file attributes updated for each new image? If so you could simply pull the newest file from the directory.

That's exactly what I'm asking how to do... I think the file attribute is only HR:Min so would'nt work if more than one picture per minute??

Bump...

Anybody got a suggestion? I need to either:

Find a way to display the last picture from a folder, or

Find a software program or script that will take the latest picture and transfer it to another folder and rename it to a standard name...

Thanks in advance

Here's a VBScript example:

dim mostRecentFileDate, mostRecentFile
strPath = "\path\to\search"
Set oFSO = CreateObject("Scripting.FileSystemObject")
Set oFolder = oFSO.GetFolder(strPath)
Set cFiles = oFolder.Files
For Each objFile In cFiles
	If(objFile.dateLastModified > mostRecentFileDate) Then
		mostRecentFileDate = objFile.dateLastModified
		mostRecentFile = objFile
	End If
Next
MsgBox(mostRecentFile & " " & mostRecentFileDate)

You could turn this into a function for your ASP page to return the latest file.

Hope this helps.

I was meaning to take a look at this for you but have been rather busy with my Touchscreen interface

Anyway, I knew I had written something several years ago which I finally found on my old Homeseer server. It's probably not so elegant as Rob's code as it uses a sort routine to re-order the files but should do what you want.

Hopefully the 3 entries you need to setup are self explanatory.

Just to recap, this will copy the latest file in a directory and copy it to a new directory with a filename of your choice.

I am attempting to do something similar. So I am hoping for some assistance. I can retrieve the current still image using the URL: XXX.XXX.XXX/Cam_1.jpg, but I would like to retrieve the last image that was captured with the systems motion dectection ie Alerts. These Alert images are stored in a folder where the folder name is the current date YYYYMMDD. The files stored in the Alerts directory & are named Cam_X__YYYYMMDD_TIME. I would like to have the file copied to a different directory, renamed & overwrite existing. This script will run on my video server pc and not HS. Motion dection will triger the script & pass the image name to the script.

Sub Main(ByVal Parms As String) 
Dim oFS
Dim StrFileName As String
Dim StrName2 As String
Dim StrFolder As String
StrFileName="cam_3_20090702_070559_1.jpg" ' TEST  file name will be passed from WebCamXp
StrName2=Left(StrFileName,5) 
StrFolder=Format(Date,YYYYMMDD)
 Set oFS=CreateObject(" Scripting.FileSystemObject" )
 oFS.CopyFile "C:\Documents and Settings\All Users\Application Data\webcamXP 5\Alerts\" & StrFolder & "\" & StrFileName, " C:\Documents and Settings\All Users\Application Data\webcamXP 5\WWWRoot\Images\" & StrName2
 
 Set oFS=Nothing
End Sub

If its any help for you all Blade has a plugin that monitors folders (on my lan in my case) and copies the latest picture to a destination of your choice (in my case to the Homeseer/html/security folder for displaying on my quickview page.

Images can be updated at timed intervals OR when the folder beiong monitored is updated.

You may be able to use a batch file to move abd rename the captured .jpg to a standard name that can be written over. If this does not involve homeseer, then it probably can be done with vbscript and/or batch files.
