Black Camera

Nanny is a wireless camera with 420 lines (black and white) look good enough to see all the details?
im looking to buy a nanny camera for my living room. I have a cleaner / dog sitter come and feed my cats and dogs and clean their messes up but lately ive seen my cat with stripes on its neck, of course I'll let her know that I have a camera present to avoid any privacy issues, but I was wondering if a camera line 420 Black and white looks pretty good to see small details. Anyone with recommendations? (seeking) Wireless thank you!
VERY Nanny cameras are of poor quality … they really fail is that they do not operate at 30 frames per second … closer to 5 frames per second … these missing frames can cause much misunderstanding. What may be the best solution is a high resolution IP camera. You can google for them
