Network Camera Server VB101

Transmitting Video Images Using a Browser OnlyDisplaying Live Video from a Specified Angleas Still ImagesBy specifying the camera angle as a parameter in the HTML code beforehand, you can displaythe image from a specified camera angle. The example below displays a still image shot with thecamera panned right by 40° and tilted down 10°.* The underscored portion is a sample IP address. Enter the actual camera server IP address.Using■GetStillImage Parametersp/pant/tiltParameterz/zoomb/back_lightcamera_iddelayDescriptionSpecifies the camera pan angle. p is a 1°unit, and pan is a 0.01°unit. Forexample if the camera pans right 20°, then p is 20 and pan is 2000. If thisparameter is omitted, the camera pan angle is not controlled.Specifies the camera tilt angle. t is a 1°unit, and tilt is a 0.01°unit. If thisparameter is omitted, the camera tilt angle is not controlled.Specifies camera zoom. z is ten times the zoom ratio of the widest angle, andzoom is the view angle in 0.01°units (horizontal direction. If this parameter isomitted, camera zoom is not controlled.Specifies camera backlight compensation. When this parameter is set to on, the imagecaptured will be bright and when this parameter is set to off, the image captured will bedark. If this parameter is omitted, camera backlight compensation is not controlled.Assigns the numbers 1 to 4 to camera 1 to 4. If this parameter is omitted, thecamera that is currently selected will be used.Waiting time until camera focus is stabilized (in milliseconds). Specified in therange 0 to 10000.Chapter 5the PictureRecording FunctionThis chapter describes a couple of specific examples of the PictureRecording function using the VB101. This function can be used toautomatically capture still pictures according to a preset scheduleor in response to inputs from an external device, and then displaythose pictures on a Web pageoptionseqSpecifies how errors are dealt with. When skip_on_error is specified, theprocess will be continued. When quit_on_error is specified, the process willbe aborted. The following errors can occur: failure to acquire camera controlright, loss of camera control, camera selection errors and camera controlerrors. To omit, the default value is quit_on_error.Allows any number to be specified to avoid displaying old images (numericvalue).cNoteIf old images are displayed, you can prevent this recurring by specifying asequence number in the seq parameter.78
