TFTP is a lightweight, lock-step protocol used primarily for bootstrapping network devices. When a Hikvision device boots up, for the first 5–10 seconds, it listens for a TFTP server on the local network. If it detects the correct firmware file ( digicap.dav ) on a server with a specific IP address, it will automatically download and flash the firmware. hikvision ftp firmware
The FTP method is a powerful emergency tool for integrators and tech-savvy users, not a daily driver. It fills a niche that Hikvision’s standard tools leave open, but it comes with no handholding. When it works, it’s a lifesaver. When it fails, you’re left guessing whether the file name, permissions, or FTP server is the issue. : Configuration > Network > Advanced Settings > FTP
