PIXY

emeet pixy would be perfect for that, dual camera ai ptz lets you move around and switch angles without touching anything, lighting handles low light situations way better than most, 4k quality is clean for streaming.

Been using emeet pixy for long sessions and no overheating or quality drop so far. Autofocus stays sharp and handles lighting changes well. Does 1080p60 smooth

for low light without ring light sensor size matters most. both those are solid but emeet pixy handles low light pretty well too if you dont need all the extra features. also webcams use barely any cpu/gpu so dont worry about that

low light is gonna be rough on any sub $100 cam tbh. even a cheap ring light makes a huge difference and you can get one for like $20. but if you really don't want lighting the emeet pixy is worth looking at. decent in low light and has auto tracking if you move around. razer kiyo is another option

Good webcam with auto light balance helps more than you think. something like emeet pixy adjusts pretty well even in bad lighting

Autofocus hunting was my biggest issue with old webcams. emeet pixy tracks smooth and low light is decent

For educational content and brand stuff you dont need obsbot or elgato honestly. Emeet pixy does auto framing and handles different lighting pretty well, way under your budget too. save the rest for a basic led panel or ring light, makes more difference than expensive webcam anyway

For desk shots and switching angles Emeet pixy handles autofocus way better than c920x, tracking keeps you centered too. Biggest upgrade is lighting, even cheap led panel makes grainy footage way cleaner

I think emeet pixy webcam handles different lighting pretty well even without crazy setup

main issue with old webcams was autofocus hunting when showing documents. also low light was trash without ring light blasting. i use emeet pixy now, tracking and auto light balance actually help for teaching. good luck with your research
