@Mike or anyone... Do you know of a circular mounting base, metal or PVC, that fits this camera or do I have to get off my lazy rear and exercise my Google Fu? It's 139 mm in diameter overall, the 3 holes are each located 120 degrees around the circle and are 110 mm apart, images below of supplied drill template and of camera base from bottom. My scanner's on the blink so I had to snap these with my phone...Hey, no jokes about my pajamas...it's early and I'm retired. EDIT: 1009; I found this Hikvision CB135 that mount with the 4 screws in that 83.5mm x 46mm rectangle, not the 3 @ 120 degrees as in the template. I have no preference. And the CB135 is 137mm overall, my 139 is likely not accurate. Unless someone comes along with a better (and cheaper) box, this could be it.
