Demo
The Demo (experience) interface lets you preview live video from representative devices without adding or logging in to any device of your own. This is useful for exploring the app's features before you have a physical device connected.
Open the slide menu and tap Demo.
The Demo screen shows a grid of demo camera feeds. Tap a thumbnail to select it.
The experience interface opens and starts playing the selected video. The preview interface supports streams switching, closing and reconnecting video, and other standard controls.
Instruction
- All icons on the experience preview interface are the same as those on the standard preview and VR preview interfaces, but only streams switching, video shutting down, and reconnecting are functional — other controls are inactive.
- When a fisheye demo is playing, the experience interface supports switching between single-screen unfolded, double-screen unfolded, tube mode, and other display modes.
- You can view the Demo without logging in to an account.
SN Login
SN Login lets you log in to a device directly by entering its serial number (SN), account, and password, giving you real-time preview, playback, capture, PTZ control, stream switching, and other operations without adding the device to your account first.
Open the slide menu and tap SN Login.
Enter the device serial number in the S/N field. The account defaults to admin; enter the corresponding password, then tap Login.
The serial number preview interface opens and automatically starts playing real-time video from the device. Tap the 
button in the upper right corner to enter the video playback interface (requires the device to have stored video).
The app automatically queries and plays the current device video. The playback timeline appears at the bottom of the screen.
The bottom toolbar provides the following controls:
