Factory CCTV maintenance should verify the complete evidence chain while respecting production, safety and site-access requirements.
Camera and physical condition
Check online status, focus, angle, cleanliness, mounting and signs of water or cable damage.
Recording and playback
Verify channel recording, time accuracy, playback and export—not only the live monitor.
Storage and retention
Review drive health, overwrite behaviour and whether actual retention meets the site requirement.
Network, power and remote access
Check PoE, connectivity, power supplies, UPS where applicable and authorised remote viewing.
Coverage and corrective actions
Document blind spots, night visibility and every recommended action with a clear priority.
