Understanding CCTV Maintenance & Operation for Security & Law Enforcement

Surveillance cameras operate continuously in challenging outdoor dust, heat, and seasonal monsoon conditions across Nepal. Regular hardware maintenance and system calibration are vital to ensure zero video loss during critical security incidents. ### Essential Routine Maintenance Checklist 1. **Optical Lens & Glass Cleaning**: Rainwater stains and urban dust reduce IR night vision clarity. Periodic cleaning ensures crisp nighttime video feeds. 2. **NVR Hard Drive Health Check**: Verify S.M.A.R.T. disk health status to detect bad sectors before drive failure occurs. 3. **NTP Clock Synchronization**: Ensure recorder system clocks match official Nepal Standard Time (NST) for accurate legal evidence timestamps. 4. **Power Supply & Battery Backup Audit**: Inspect UPS batteries and PoE switch power budgets to maintain continuous recording during power outages. ### Specialized Orientation Workshops At E Three Sales and Services Pvt.
