The first issue is whether they have permission to instal cameras. A by lawpreventi g changes to common property would cover this.
Se only, if they have permission, they are only allowed to record common property. Common property is a public area, so as long as the camera does not record inside a lot its legal.
I would also be bringing up with the committee, the relevance of cameras. If the lot owner claims its for their security, they should only record what’s relevant. ie their front doo, their garage, but not areas not associated with them.
