Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe. The actual developer of this free software for Mac is SpenceCore. The application is included in Design & Photo Tools.
From the developer:
SCSnapShotIP is a basic photo application that supports zooming, panning, rotating, mirroring, and framing of both the image preview and capture from IP cameras supporting Http Live Streaming (HLS). This tool mimics many of the features provided by the macOS version of 'SCSnapShot' for USB and built-in cameras.
The application fully saves and restores the state of each camera connected. This makes scanning though multiple cameras simple.
