Can I Legally Videotape Our Babysitters?

The idea of trusting someone to watch our child while we’re gone frightens me, but I know it is something we’re going to have to do. Does anyone know if it is legal to have hidden cameras, maybe in the living room and child’s room to be sure that our child is being treated properly? Would I have to let the babysitter know about this?

I live in Mississippi, in case anyone knows any particular law pertaining to MS….
