I've gotten 3 recommendations from Fryes Electronics: The Swan, (they say makes the best products), The QC, and the Lorex, (this one has a motion detector). Anyone heard of these, there's also an sc card we'll have to purchase. Pricing ranges from $199.00 to $249.00 and that doesn't include the sc card of 32 gigs, which is $69.00
I used cameras from x10.com and other 'pieces' so I could record on my 'old' vcr. Since I was the one mostly here with Mom I didn't need as sophisticated a system, and the 'night vision ones' I got from x10.com worked nicely for me.
I posted on your other 'topic' about the legalities of recording anyone. I do hope you get the level of comfort from the camera that you choice. I could not have managed without the ones installed in my home.
