What screws are used to fix the surveillance camera bracket on the wall?

Choose 6mm plastic expansion+self-tapping screw, because the expansion screw uses the inclination of wedge to promote expansion and produce friction grip, so as to achieve the fixed effect. The surveillance camera bracket can be firmly fixed on the wall.

In addition, pay attention to the depth when drilling the expansion pipe. The 6mm expansion tube is about 5 mm deeper than the length of the expansion tube when drilling.
