Monitoring Real-time Movement Using Video View

If the target panel is Windows based device with the HMI Runtime, you can monitor the real-time movement from the connected USB camera by using video view. And the live image can be saved in the JPG or BMP file.

If the target panel is X series HMI unit, it can connect an analog color camera with the signal format of NTSC or PAL. You can do the following with the video input:

1) Show the video view on the screen in near real time. The image resolution is 640H by 480V.

2) Take a picture and save it in a pre-designated storage device with a time stamped filename.

3) Freeze the camera view for some inspection purpose.

4) Save the frozen camera view in a selected storage device with a selected filename.

5) Unfreeze the camera view.

6) Stop the camera input.

7) Load a taken picture and show it on the screen.

8) Record the video view in up to five videos. Each video has a maximal length of 3 minutes. Therefore, the HMI panel can always keep the last 15 minutes of the video view in its NAND Flash.

9) Copy a recorded video to a file. Therefore, you can play the video with your PC.

10) Select a recorded video and play it on the screen.
