Description

PTZOptics and possibly other ValueHD-based pan-tilt-zoom cameras use hard-coded, default administrative credentials. The passwords can readily be cracked. Many cameras have SSH or telnet listening on all interfaces. The passwords cannot be changed by the user, nor can the SSH or telnet service be disabled by the user.
