ONVIF is a standard for video surveillance and security applications, developed by the video surveillance industry and implemented by various vendors. The standard is based on web-based communication, allowing for easy interaction and for remote management of video surveillance systems.

It allows users to remotely monitor and control IP cameras via a browser on a smartphone or a tablet. The app also provides a means for users to view snapshots of cameras, which will be updated periodically. You can also view the status of the camera and check the video stream from the camera.

The app allows users to create a list of cameras, which can then be viewed and managed from one place. Users can manage the cameras and view their video streams and snapshots. The app will also allow users to add a list of users, and it will be available for those users.
