To resolve this issue, you need to adjust the camera's frame rate through the camera's OSD Menu. Follow these steps:

1. Right-click on the channel and select PTZ Control.

2. Double-click the 360° rotate button to open the OSD Menu.

3. Use the Up/Down/Right/Left buttons to navigate through the OSD Menu.

4. Check the FORMAT. If the resolution displays 2MP25 (25FPS), it is set to the PAL system.

5. Use the Right/Left button to switch it to 2MB30 (30FPS), which is the NTSC system.

6. After switching the FORMAT according to your requirement, press the Down button to navigate to SAVE - EXIT, then click the 360° rotate button to save the settings.

2. Click General.

3. Select the Video Standard to PAL / NTSC, according to the camera FORMAT then click OK to save the settings.
