Lesson 1Imaging performance and configuration: resolution, frame rate, exposure/iris, WDR, gain/AGC, white balance, IR illumination checks and time/date accuracyValidate image quality and camera settings. Check resolution, frame rate, exposure, WDR, gain, white balance, IR, and time sync for usable footage in all lighting on Namibian sites.
Resolution, codec, and frame rate verificationExposure, shutter, iris, and WDR adjustmentsGain, noise reduction, and low-light tuningWhite balance and color rendition checksIR illumination coverage and time/date syncLesson 2Optics and focus tests: focal length, back-focus, iris settings, auto/manual focus checks, and depth-of-field verificationVerify and optimise camera optics and focus. Check focal length, back-focus, iris, autofocus, and depth of field for sharp images across key areas.
Focal length selection for scene coverageBack-focus adjustment on varifocal lensesIris mode, F-number, and motion blur impactAuto versus manual focus verificationDepth-of-field tests at near and far pointsLesson 3Recording and storage verification: DVR/NVR model, disk health (SMART), RAID/configuration, retention calculations, overwrite settings, and video export testConfirm recording and storage meet needs. Verify NVR models, disk health, RAID, retention, overwrite rules, and test exports for compliance.
DVR/NVR model, firmware, and capacity reviewDisk health, SMART status, and bad sector scanRAID configuration and rebuild monitoringRetention calculations and overwrite policiesTest recording, playback, and export workflowLesson 4Network and bandwidth checks: IP addressing, PoE power delivery, switch port status, VLANs, QoS, latency tests, and camera streaming bitrate analysisConduct network checks affecting camera reliability. Validate IP, PoE, switch ports, VLANs, QoS, latency, packet loss, and bitrates vs bandwidth.
IP addressing, subnet, and gateway validationPoE power budget and port load checksSwitch port status, errors, and negotiationVLAN, QoS, and multicast configurationLatency, jitter, and camera bitrate analysisLesson 5Tools for CCTV checks: network tester, PoE tester, CCTV monitor, lens cleaning kit, laptop with VMS client, USB storage for exports, SMART disk utilityEssential tools for CCTV field checks and safe use. Includes network/PoE testers, monitors, cleaning kits, VMS laptops, USBs, and disk utilities for diagnosis.

Test timeline, search, bookmarks, exports, and chain-of-custody docs.
Timeline navigation and gap detectionEvent, motion, and metadata search testsBookmarks, tags, and case organizationExport formats, codecs, and player checksEvidence export logs and chain-of-custodyLesson 8Physical camera inspection: lens cleanliness, housing integrity, mounting stability, sun/IR shielding, and vandal protection checksSystematic check of camera physical condition. Verify lens/dome cleanliness, seals, mounts, cable relief, sun/IR shields, and vandal features.
