Lesson 1Lens kinds and view areas: focal length, side view, pixels per meter for knowing vs seeingUnderstand lens kinds, focal lengths, and how dem shape the view area. Learn fixed, varifocal, and moving lenses, side view, and how to figure pixels per meter for seeing and knowing things.
Fixed vs varifocal vs motorized lensesFocal length and angle of view basicsHorizontal FOV vs scene coverageCalculating pixel density per meterID, recognition, and detection targetsLens distortion and edge sharpnessLesson 2Clearness, sensors, and night work: HD/2MP/4MP/4K, WDR, IR, starlight, and noise choicesUnderstand how clearness, sensor size, and night tech affect picture sharp. Learn WDR, IR, and starlight ideas, noise choices, and how to match pixel count and feel to knowing and seeing goals.
