The WiCam application will be able to display images from multiple webcams and change the selected webcam's orientation if it is equipped with appropriate pan and tilt capabilities.

The accelerometer sensor, located within the iPhone, feels acceleration from external forces such as setting the iPhone in motion or stopping the iPhone from moving. The pan and tilt functionality will be controlled using the acceleration due to gravity felt by the iPhone in the x, y, and z axis. Alternatively, the pan and tilt functionality will also be available through touch screen buttons on the iPhone screen.

URL Parameter PassingURL Parameter Passing

The WiCam team would like to thank the following individuals for their support throughout the duration of course project:

This technique was the main interfacing method used to remotely control the webcams used within this project. URL parameter passing first involves determining the address of the desired webcam. This can be either an IP Address or it can be a host name. The primary camera addresses used for this project were:

Panasonic BL-C131A PTZ Webcam: ptzsenior.viewnetcam.com (pan/tilt capabilities)Axis 205 Webcam: axis205.rit.edu (no pan/tilt capabilities)

Following this, commands could be sent to the webcams by appending the appropriate arguments to the end of the address and entering it within the URL address bar. This made for a very simple interface.Command Description Parameter Restrictions

FunctionDetermines the operation to be performed

Func Can be set to Pan or Tilt

Authorization Sets the authorization KindCan be set to 0 (General User) or 1 (Adminstrator)

Pan/Tilt Direction

Determines which direction the camera will move

DegModeCan be set to 2 (Tilt Down), 4 (Pan Left), 6 (Pan Right) or 8 (Tilt Up)

URL parameter passing arguments used to interface to the Panasonic PTZ webcam

Example URL Command:http://129.21.27.169/Set?Func=Tilt&Kind=0&DegMode=2 - Tilts the webcam down by 5 degrees
