Nobody here has residential air conditioning. The heat is on just now.
It\'s officially 61F right now, but our neighborhood runs colder, 58
right now. A ceiling fan is great for the rare hot days that we have.

Ceiling fans are amazing. Quiet, reliable, cheap.

Well, until the capacitors in the speed control box degrade. Mine got to
the point where the choices were exceedingly slow, very slow, or
gale-force. Of course, a trip to the electronics store fixed that, but
not an option for most people.

Oh, yes, and it is mounted on a crossbeam that is attached to the joists
by large steel brackets and substantial screws. It\'s not going anywhere.

I\'m installing a PTZ camera on a ceiling. The unit weighs
a bit less than a kg.

The documentation claims:

When installing the unit in a high location, be sure
that the location and installation components (excluding
the supplied accessories) are strong enough to withstand
at least 60 kg of weight, and install the unit securely.
If the components are not strong enough, the unit may fall
and cause serious injury.

I can\'t see from where the *60* kg requirement derives.

Is this thing made in or sold in Europe? The various building codes put requirements on the dead loads and live loads the structural ceiling is required to support. They\'re specified in pounds per square foot in U.S. - there are always exceptions and additional requirements you would have to check the residential code of the IRC to verify. So forget that. The majority of that 60kg pertains to the weight the ceiling is rated for to hold itself up.. They don\'t want you hanging if off something flimsy like a suspended ceiling, drywall, or some cheap ass 2x2s you can effortlessly break over your knee. Use 150 lb *pullout* fasteners, which are pretty small, cheap and readily available, and attach them to *good* framing.
