Cam mount for rain pipe (IP/ Network Cam with standard footprint)

This is an IP CAM mount to attach the cam on a rain tube or fix it on other parts with one screw (centered).
It should work with nearly all chinese standard IP Cams (HIKVISION, S3VC, etc), if the distance between the three holes is around 41-42mm (see photos).
To fix the mount on the rain tube, you need:
- a standard bossed clamp (with your rain-tube diameter) with m8 thread
- m8x10 or m8x12 screw
- m8 washer
- 3x screws (delivered with cam)
