Are you looking for a Nanny cam with a built in recorder? This is just what you need. The Nanny Cams below all have recorders inside them. Some nanny cams with sd card recorders accept up to a 32 Gig sd card for 64 hrs. Of continues recording. Other self recording nanny Cams have built in Memory.
How do I know the difference? If the Nanny Cam offers an SD card upgrade with the unit it means the sd card is removable. If the Nanny Cam offers a memory upgrade or no upgrade other than audio, it means it had built in memory and there is no removable sd card.
Hope This Helps.
