I've been trying to find those things around here with no luck. All the stores have long since changed the style of vinyl siding they sell but none stock the "new" style quick and easy siding mount kits like those to match what they've been selling for siding for the last 20+ years. They've all got the wrong notch pattern in the back believe it or not. This reminds me that I haven't tried mail order yet. Thx.
Drill the top plate easily because it's plastic.
All four side plugs fit very snug, but you could glue them of course.
Drill any one (or more) of the side plugs with a hole just large enough for the Cat5 cable to slip through, do your crimpingafter the cable is pushed through, then when everything is sealed up in the j-box, just a touch of silicone around the cable and slip it in another 1/4 inch to make sure it seals too.
Oh yeah... and they're already grey to match my house. (YMMV)
Yes but they'll wiggle a bit in heavy wind if there isn't something solid to screw into other thsn plastic soffit. Not a huge deal because if it is windy enough to screw up the motion detection from wiggling there's most likely other stuff blowing that'll set it off as well. Just don't over torque the screws beyond snug or your bullet might eventually end up blowing in the wind.
