SADP stands for search active device protocol, it's Hikvision's free and simple utility for searching Hikvision products (including IP cameras and DVRs/NVRs) in the local network. Hikvision SADP software supports Windows OS only, is available for Microsoft Windows 8.1, Windows 8, Windows 7, Windows 2008 - 32/64-bit, Windows XP, Windows 2003 - 32-bit. In addition to searching Hikvision devices, this online device search tool can also be used for modification of network parameters of the Hikvision devices, including the change of passwords or recovery of default passwords (when the user lost/forgot a password). It can eliminate problems with duplicated IP addresses (often occurring after connecting a number of new devices), even in the same network class.
