    Hikvision - Clearing Passwords and/or Loading Firmware via TTL Serial

    I recently picked up a used Hikvision DS-7608NI-E2/8P (at auction) that was password locked. The seller was unable to tell me where it was sold, and all the Hikvision offices I contacted (US, EU, AU, CN, HK) provided the canned "purchased through an unauthorized" channel response. The stated...

    Camera console connection via UART
