I'm guessing inexpensive cameras (eg: 50GBP dome cameras) will be a useful addition for presence sensing ... and that maybe one per room, on the ceiling & near a corner, would be good, given unobstructed views ... with obstruction, some rooms might need two, or more ... ... but am I right ? Our card can cope with four cameras ... one in each main room, maybe ... is that going to be enough ? Has anyone actually tried augmenting reed-switches & PIRs with cameras, yet ??
How about sound, too - dead-of night should be still & quiet, so noise & motion mea there's maybe a problem - what sort of camera- & sound-sensors might make sense ?
Any thoughts ... ??
