Working: Grandtec IP Cam Pro (III) / Conrad Grand IP Camera

Post by sirell » Thu May 14, 2009 7:03 pm

Hi there,

just playing with the Conrad Grand IP Camera which is indeed a grandtec IP CAM 3.
Stills working with about 3-5 fps.
The Crap of jpeg header in the mjpeg stream can be removed with
the script at the end of this post (i found it here but can`t find anymore the origins) but it seems to be the very same image quality.
The max. Framerate is also the same.

Image Quality is what you pay for ( about 95 Euro)...
The Cam here has the night view lens (without ir filter).
This renders the cam useless for outdoor views as ANY IR-Source will overexposure the hole picture. Also indoor is very lightning critical. The cams autoexposure seems to be useless.

Also you can patch ZM like this:
The Offset is 35 bytes.

Hostname: IP or host of cam
Hostpath: /still.jpg
Maybe you must prepend with username:password - but this can be fully disabled in the cams Webinterface.

I also tried to use another Firmware (an Hama modell may be the same or very similiar) but then the cam think it is an images anymore.

If you have questions - just ask.



Code: Select all

function handlejpeg($bork,$i) {
  echo "--video boundary--\r\n";
  echo "Content-length: ".strlen($jpeg)."\r\n";
  echo "Content-type: image/jpeg\r\n";
  echo "\r\n";
  echo $jpeg."\r\n";
  @ini_set('zlib.output_compression', 0);
  @ini_set('implicit_flush', 1);
  Header('Content-Type: multipart/x-mixed-replace;boundary=--video boundary--');
  $handle = fopen("", "r");
  if ($handle) {
    while (!feof($handle)) {
        $buffer = fgets($handle, 409600);
        if($start==0 && $buffer=="--myboundary\r\n") {
          $crap = fgets($handle, 409600);
          $crap = fgets($handle, 409600);
          $jpeg=fgets($handle, 409600);
        } elseif($start==1) {
          if(preg_match("/--myboundary\r\n/",$buffer)) {
            $crap = fgets($handle, 409600);
            $jpeg=fgets($handle, 409600);
          } else {
