Motion Scripts

We use two bash scripts to manage motion data. One simply copies the last snapshot to the live web server for the main domain to link to.

  • imagedelay.sh
cp /motion/1.camera.midsouthmakers.org/lastsnap.jpg /motion/camera.midsouthmakers.org/delayed-1.jpg
cp /motion/2.camera.midsouthmakers.org/lastsnap.jpg /motion/camera.midsouthmakers.org/delayed-2.jpg
cp /motion/3.camera.midsouthmakers.org/lastsnap.jpg /motion/camera.midsouthmakers.org/delayed-3.jpg
cp /motion/4.camera.midsouthmakers.org/lastsnap.jpg /motion/camera.midsouthmakers.org/delayed-4.jpg
cp /motion/5.camera.midsouthmakers.org/lastsnap.jpg /motion/camera.midsouthmakers.org/delayed-5.jpg

Our second script rotates the previous day's images into it's own archive folder and copies an easy to view gallery.

  • archivemotion.sh
#!/bin/bash
DATE=`date -d '1 day ago' +%Y-%m-%d`
echo $DATE
PATH1="/motion/1.camera.midsouthmakers.org/$DATE"
echo $PATH1
mkdir $PATH1
mv /motion/1.camera.midsouthmakers.org/$DATE-* $PATH1/.
cp /motion/1.camera.midsouthmakers.org/galleryarchive.php /motion/1.camera.midsouthmakers.org/$DATE/index.php
#
PATH2="/motion/2.camera.midsouthmakers.org/$DATE"
echo $PATH2
mkdir $PATH2
mv /motion/2.camera.midsouthmakers.org/$DATE-* $PATH2/.
cp /motion/1.camera.midsouthmakers.org/galleryarchive.php /motion/2.camera.midsouthmakers.org/$DATE/index.php
#
PATH3="/motion/3.camera.midsouthmakers.org/$DATE"
echo $PATH3
mkdir $PATH3
mv /motion/3.camera.midsouthmakers.org/$DATE-* $PATH3/.
cp /motion/1.camera.midsouthmakers.org/galleryarchive.php /motion/3.camera.midsouthmakers.org/$DATE/index.php
#
PATH4="/motion/4.camera.midsouthmakers.org/$DATE"
echo $PATH4
mkdir $PATH4
mv /motion/4.camera.midsouthmakers.org/$DATE-* $PATH4/.
cp /motion/1.camera.midsouthmakers.org/galleryarchive.php /motion/4.camera.midsouthmakers.org/$DATE/index.php
#
PATH5="/motion/5.camera.midsouthmakers.org/$DATE"
echo $PATH5
mkdir $PATH5
mv /motion/5.camera.midsouthmakers.org/$DATE-* $PATH5/.
cp /motion/1.camera.midsouthmakers.org/galleryarchive.php /motion/5.camera.midsouthmakers.org/$DATE/index.php

Gallery Sciprts

We use 2 gallery scripts, one lists folders to be placed in the root of the individual camera folder, the other is to be copied into each archived folder.

  • gallery.php
<?php
ini_set ('display_errors', 1);
error_reporting (E_ALL & ~E_NOTICE);
function folderlist(){
  $startdir = './';
  $ignoredDirectory[] = '.'; 
  $ignoredDirectory[] = '..';
   if (is_dir($startdir)){
       if ($dh = opendir($startdir)){
           while (($folder = readdir($dh)) !== false){
               if (!(array_search($folder,$ignoredDirectory) > -1)){
                 if (filetype($startdir . $folder) == "dir"){
                       $directorylist[$startdir . $folder]['name'] = $folder;
                       $directorylist[$startdir . $folder]['path'] = $startdir;
                   }
               }
           }
           closedir($dh);
       }
   }
return($directorylist);
}
echo("<table><tr><td>Past Archives</td></tr>");
$folders = folderlist();
  foreach ($folders as $folder){
    $path = $folder['path'];
    $name = $folder['name'];

    echo '<tr><td><a href="'. $path . $name .'">' . $name . '</a></td></tr>';
  }
echo("</table>");  
// open the current directory by opendir
$handle=opendir(".");
	$images = array();
	$videos = array();
	$imagestring = ".jpg";
	$videostring = ".mov";
while (($file = readdir($handle))!==false) {
if ($file == "." || $file == ".."){
	//nothing
} else {
	
	//echo "$file <br>";
	if(strstr($file,$imagestring)) {
		//echo "found it.";
		//echo("$file : " . date ("Ymd Gis", filemtime($file)) . "<BR>");
		$imagedate = date("Ymd Gis", filemtime($file));
		$images["$imagedate"][] = "<img src=\"" . $file . "\">";
		//$images[] = $file;
	} else {
		//echo "not found.";
	}
	if(strstr($file,$videostring)) {
		//echo "found it.";
		$videos[] = $file;
	} else {
		//echo "not found.";
	}
}
}
sort($images);
//ksort($videos);

foreach ($images as $imagelink) {
	//echo("$imagelink");	
	foreach ($imagelink as $key=>$temptwo) {
      echo "$temptwo", "\n";
    }
}
closedir($handle);

Apache Configuration

Six site files make up the local Apache server. This allows us to serve the camera data from a secondary location to our main web server.
