Monitoring system routine maintenance checklist

Daily

• Spot check the real-time images of key channels to confirm that the images are normal and unobstructed.
• View system alarms (offline, hard disk abnormalities, capacity alarms).
• Confirm that the video is being written normally.

Weekly

• Playback spot check: Randomly check at least 1 channel in each partition to confirm that the video is complete and the time is accurate.
• Check the remaining storage capacity and the estimated number of days it can be stored.
• Check the online rate of equipment and process offline points.
• View the hard drive SMART status.

Monthly

• Clean the camera lens and protective cover (especially outdoors, in the kitchen, and in dusty environments).
• Check the fastening and corrosion of brackets, poles, and equipment boxes.
• Check whether the outdoor joint waterproofing is intact.
• Check the system time (the deviation from the NTP server should be < 1 second).
• Export and archive important event recordings.
• Check UPS battery status.

Quarterly

• Check the lightning arrester and grounding resistance (must be done before thunderstorm season).
• Clean equipment boxes, fans, and dust screens to improve heat dissipation.
• Check switch port status and error count.
• Recheck account permissions and clean up the accounts of resigned personnel.
• Update device firmware (verify at non-critical points first).
• Check whether the point ledger is consistent with the actual situation.

Every year

• Comprehensive assessment of whether storage capacity will meet demand for the next year.
• Evaluate the life of the hard disk (monitoring disks are recommended for preventive replacement every 3 to 5 years).
• Check whether the vertical pole foundation has settled or tilted.
• Review the lightning protection grounding system.
• Practice a fault recovery process and verify that the backup is available.
• Update as-built drawings and location ledgers.

Recommended records

• Point ledger: number, location, model, IP, coverage, installation date.
• Device list: model, serial number, firmware version, warranty period.
• Network planning: IP allocation table, VLAN, port correspondence.
• Maintenance records: time, reasons, and results of each inspection and troubleshooting.
• Account list: users, permissions, activation and cancellation time.
