When you add a camera to the screen, the camera control will be displayed:
This view control is similar to the live camera view control, but with limited video playback capabilities.
The following information will be provided in the camera header:
•Name and/or Description of the camera.
•Playback time.
•Frames per second recorded (referring to the second currently being displayed).
•Image resolution.
•Current video frame number / Total number of video frames.
•Type of video compression.
•Image authenticity watermark: When the image coming from the camera is recorded on the disk, a security code is generated based on this image. If the image is altered for any reason, the authenticity code is broken, displaying the value Invalid on the screen. The video player will not allow the export of a video frame that has an invalid watermark.
This object has a simple context menu, accessible by right-clicking on the image:
•Save Image: Saves the current image to disk. When you select this option, a dialog window will appear in which you must select the name of the destination file and its format. The system allows you to save the image in the following formats: JPG, BMP, PNG, WMF, GIF, TIF.
It is possible to perform Digital Zoom on images from cameras in playback. The Digital Zoom control is identical to the live mode. To learn how to operate Digital Zoom on cameras in playback, see the topic on Moving via Digital Zoom.
