How to send command from matlab to my IP camera

Hi,

I really need help on this. How to send command from matlab to my ip camera for me to control my camera. Below is the javascript(function) of my camera. im using foscam fi8918w. Thank you.

var PTZ_STOP = 1; var TILT_UP = 0; var TILT_DOWN = 2; var PAN_LEFT = 6; var PAN_RIGHT = 4; var PTZ_LEFT_UP = 91; var PTZ_RIGHT_UP = 90; var PTZ_LEFT_DOWN = 93; var PTZ_RIGHT_DOWN = 92; var PTZ_CENTER = 25; var PTZ_VPATROL = 26; var PTZ_VPATROL_STOP = 27; var PTZ_HPATROL = 28; var PTZ_HPATROL_STOP = 29; var IO_ON = 95; var IO_OFF = 94; var FILE_NO =1;

function up_onmousedown() { if (ipcam[current].MonitorStatus != 2) return;

up.src = up_down.src; if (ipcam[current].CameraFlip & 0x01) ipcam[current].DecoderControl(TILT_DOWN); else ipcam[current].DecoderControl(TILT_UP); }

function up_onmouseup() { if (ipcam[current].MonitorStatus != 2) return;

up.src = up_up.src; ipcam[current].DecoderControl(PTZ_STOP); }

function down_onmousedown() { if (ipcam[current].MonitorStatus != 2) return;

I don't know much about image acquisition with MATLAB, you might find this previous discussion useful: http://www.mathworks.com/matlabcentral/answers/11011-how-to-access-video-from-a-remote-camera

Hi kaustubha, I know how my camera function works but really doesnt know how to connect the javascript and the matlab together. Do you have any ideas on how to call javascript function on the matlab?

[Kaustubha Govind]

Not sure, but if you know how to call your Javascript function using a COM object, you can use MATLAB as a COM client: http://www.mathworks.com/help/techdoc/matlab_external/f27178.html
