does this product have to be plugged into wall socket or is it battery operated/rechargeable?

It must be plugged in. It is not battery powered.

Does it have a card slot for added memory?

YES it does - and the motion sensor is a nice feature. Bought it for my father so it requires no effort on his part. Good product
