I used the spare M3x18 screw and a nut from the LED Strip to fix my ESP32 Cam housing.
It is easily adjusted with a ball joint that can be fixed by screwing it tight.
I used a different lens than the standard lens for having a little better quality. It is a 28MM 75 Degree and I bought it on aliexpress.
The rest is the standard ESP32 Cam and the motherboard with its USB connection.
