I've been testing Motion (the Linux CCTV software) with viewerframe mode for a local security project in Buenos Aires. While it's powerful for remote monitoring, leaving ?action=snapshot or viewerframe accessible without authentication is risky.
Older IP cameras operate as standalone web servers. When connected to a local area network, they use specific paths (like /view/viewerframe.shtml ) to render video controls through basic HTML frames, Java applets, or ActiveX controls. 2.
