RECORDING AND PLAYBACK CONTROL

Record Mode

RECORD button

Pressing the Record button starts image capture operation. Video frames captured from the camera are stored first in the system memory in a circular buffer. An independent execution thread stores video frames from the buffer on the RAID disks. During DVRP operations, the image area at the main application window is continuously updated with the latest video image from the camera at a refresh rate that depends on camera characteristics and system configuration. The refresh rate might be lower then the camera frame rate to prevent disturbance to system performance.

The capture operation continues until the user presses the Stop/Pause button or until expiration of the predefined time period - if timer check-out box was selected in the "Select Files" dialog

PAUSE button

Pressing the Pause button pauses the capturing operation until Record / stop button is pressed.

STOP button

Once a recording command is initiated, the Stop button stops the acquisition process of the images and storing of images to the buffer.

Play-Back Mode

Pressing the Play button starts image playback operation. An independent execution thread fetches frames from the disk and refills the buffer. During DVRP operations, the image area at the main application window is continuously updated with the latest video image. In playback mode, the video frame rate is user defined using rate controls on the main windows.

The playback operation continues until the user presses the Stop/Pause button or until the end of file/s.
