This holder has been made for EUFY securuty cameras to be mounted to rainwater pipes with 120mm diameter.
Background information: In our case we mounted an Eufy S330 solar driven wireless camera. The original cam holder was WHITE so we painted it BLACK and bought a black silicon housing for the cam on Amazon, too.
6 screws needed: The holder consists of TWO parts. You need four 4x20mm screws for the ring holder an two 3x12mm screws for the cam mount to be screwed to the ring holder.
Have fun.
