The operation of Mac CCTV video software is similar as windows CMS5. Some of the function may be not available with Mac version. You can watch the live video, playback and download the recording files on the camera, or configure the camera to improve the light condition. As VMS doesn’t support P2P cloud connection, if you want to access the camera remotely with Mac OS, you will have to manual port forwarding the TCP port (34567) on your router.
