I needed a solution to mount a REOLINK RLC-1240A camera on a socket.
I used ABS because of the weatherresistance of this material.
You may use additional M4 threaded inserts an M4x20 bolts. 
With an M6 or 6mm screw the whole box can be mounted on any surface.
Just connect the PoE cable in this box to the harness, srew with M6 or 6mm scre the box on any surface and srew the camera with M4x 20mm on this box.
If this model helps you, please consider to send a boost or at least a Thanks and comment.
