Does the owners corporation require a by-law to install something on its own property?
I think you may be setting the bar a little high for yourself there as a by-law requires a 75 per cent vote but a simple resolution only needs a simple majority.
Just put it in as an agenda item that the committee investigates the options, with a due date for reporting back (or it may well be stalled).
If you get your motion in on time, then it has to be discussed and voted on at the AGM.
