Surveillance infrastructure shapes daily life: retail monitoring, residential security, municipal cameras, and even small industrial installations rely on these systems. Firmware decisions ripple into privacy and operational resilience. A patched codec that reduces storage needs can make longer retention feasible; a firmware flaw can expose streams to interception; a modified image can create a persistent backdoor across dozens of deployed devices. The tension between patching for capability and preserving secure, auditable systems is particularly acute because many installations are managed by small teams without dedicated firmware‑management processes.
