Task	What to Do	Frequency	Notes for Malaysian Climate
Camera housing & lens	Clean glass/dome, check for cracks	Quarterly	Humidity causes mould—use lens-safe alcohol wipes
IR LEDs & night-vision lamps	Verify glow, replace dim units	6 months	Prolonged 35 °C heat shortens LED life
Cables & PoE connections	Inspect for fraying, rust, loose RJ45	6 months	Coastal areas: add silicone grease to prevent corrosion
Power supply / UPS	Test battery backup, measure voltage	6 months	Frequent thunderstorms → higher surge risk
Firmware updates	Patch cameras, NVR, mobile app	Quarterly	Close cybersecurity gaps before exploits emerge
Hard-disk health	Run S.M.A.R.T. test, check hours-in-service	Quarterly	Replace after 18 000 h (~2 years) to avoid sudden failure
Recording verification	Play back random clips from each camera	Monthly	Ensures motion schedules & retention length are correct
Time sync & watermark	Confirm NTP server and legal watermarking	Quarterly	Mandatory for footage admissibility in court
Physical mounting	Tighten brackets, realign field of view	6 months	Seasonal wind may nudge outdoor bullets off-axis
Clean NVR rack & fans	Vacuum dust, check fan RPM	Quarterly	High dust in construction zones clogs airflow
