Redid my security lighting again. I suppose I'm a bit obsessive that way but I'm satisfied now. I replaced the garden lights with brighter, solar-powered lights mounted on my house corners for $120. Their solar panels and batteries are 3X larger and coverage is 2000 sq ft so they act like a zone coverage. I left a few strategic garden lights in place.
A fully-integrated system would be nice but it would cost at least 10x more for the equivalent coverage and I'd be locked into a proprietary scheme.
