Mounting to Soffit with no backing?

[Sybertiger]

My aluminum soffit is not rigid enough to properly support the cams. This is, in part, the reason for using aluminum flat bar. Second, the only hole to be made is one just large enough for the Cat6 which is easily plugged with a tiny rubber plug should the camera be removed.

I route the cable in a groove of the soffit that is covered by the aluminum bar. If you don't have grooved vinyl soffit that won't work, but if you do there's no holes at all. To access for wiring I bend the flange of the channel at the gutter side out of the way, it's thin aluminum, and slide a whole section of soffit out for convenience. Bending the flange back into shape, fingers only, only takes a minute or two.
