Show HN: CheapSecurity – Lightweight, Self-Hosted CCTV for Linux SBCs | Hacker News

Hacker News discussion around CheapSecurity focused on the quality of motion detection, not just cheap self-hosted CCTV.

Commenters said basic frame differencing in low-cost cameras is too unreliable and triggers too many false alerts.

By contrast, Nest-style human detection was praised as more accurate, but it often depends on cloud services.

The main ask was for a lightweight, self-hosted person-detection approach that can run efficiently on Linux SBCs.
