Read the first 7 Preventive Maintenance Schedules flashcards as text

  1. How often should PTZ camera lubrication and mechanical movement checks typically be performed?

    Answer: Quarterly

    PTZ camera mechanical components such as gears and motors should be inspected and lubricated on a quarterly basis to prevent premature wear.

  2. Which document should a technician reference to determine the manufacturer-recommended cleaning interval for a camera dome housing?

    Answer: Installation manual or maintenance guide

    The manufacturer's installation manual or maintenance guide specifies recommended cleaning intervals specific to the equipment model.

  3. A maintenance log shows a DVR's hard drive has been in continuous operation for 3 years. What preventive action is most appropriate?

    Answer: Plan for hard drive replacement

    Hard drives have a finite operational lifespan, and proactive replacement after 3 years of continuous use prevents unexpected recording loss.

  4. What is the primary purpose of checking camera IR illuminator output during a preventive maintenance visit?

    Answer: To verify adequate low-light imaging performance

    IR illuminators degrade over time, so verifying output ensures the camera maintains effective night-vision coverage.

  5. During a scheduled PM, a technician finds condensation inside an outdoor camera enclosure. What is the correct response?

    Answer: Dry the enclosure, inspect for seal failure, and replace gaskets if needed

    Condensation indicates a compromised seal; drying the unit and replacing failed gaskets prevents moisture damage to internal electronics.

  6. Which NVR/DVR maintenance task is best performed during a low-traffic recording period?

    Answer: Firmware updates and system reboots

    Firmware updates and system reboots briefly interrupt recording, so scheduling them during low-activity periods minimizes potential gaps in coverage.

  7. A PM schedule calls for verifying UPS battery backup for surveillance equipment. What is the most important test parameter to check?

    Answer: Battery runtime under load

    Battery runtime under load confirms the UPS can sustain surveillance equipment for the required duration during a power outage.
