Review on Longruner Day & Night Vision Camera For Raspberry Pi: 1080P HD Video With 5MP OV5647 Sensor - Perfect For RPi 4, 3B+, 2B, Zero W & More! by Matt Kovacevic
The IR LED cutoff is adjustable
Just got it today, so I'll come back and update this more after I've had a bit more time to play around with it, but it's worth noting that the IR LEDs--which do generate quite a lot of heat--use a physical light sensor as their cutoff.
The sensitivity of this sensor is adjustable via a tiny (TINY) adjustable screw on each of the two LED circuit boards--tighter = less sensitive (turns off more easily), looser = more sensitive (stays on under brighter conditions). I think they ship almost fully loosened, which is why I'm seeing a lot of reviewers saying they're always on: I had the same issue initially.
- The switch between night and day does not always happen as it should.
- This does not work with the 64 bit raspberry pi os
