Finding every IP camera, NVR, and DVR on a local network can be surprisingly difficult. Devices may advertise themselves through ONVIF or mDNS, expose only an RTSP service, use a vendor-specific web endpoint, or respond on an unexpected port. CamScan brings these clues together in one Bash-based discovery tool designed for networks you own or are authorized to test. The open-source project is available on GitHub at error0327/CamScanner . It is designed and tested around Kali Linux, while also including fallback package mappings for other supported systems where possible. What makes CamScan useful? CamScan does more than look for a single port. It combines multiple discovery and fingerprinting signals, then scores each host as a possible, likely, or confirmed camera device. This helps reduce noise while still surfacing devices that may not identify themselves in an obvious way. Scans a subnet, IP range, or individual host. Uses ARP discovery when available, with an Nmap p...
