Nanny Camera Fail

I was going through nanny camera footage and I found some things that were odd and annoying, but not related to children. I was wondering if anyone else ever had this experience/problem.

Reviewing (quickly) 80 hours of footage:
-Nanny opens freezer atleast nine times and eats ice cream out of the half gallon container with her fingers.
-Nanny vacuums stove top.
-Nanny sings into vacuum hose.
-Nanny takes approximately 1,000 selfies
-Nanny chases dog, unsure if it is menacing or a game
-Nanny comes to vitamin cupboard, selects vitamins(?) puts in blender with yogurt. Applies to face.
-Nanny takes off her jeans, irons them on kitchen counter, puts them back on
-Nanny (and oldest son) seen running at mach speed towards sofa in family room, doing somersault and landing in flip on sofa.
-Nose picking, ear picking, cleaning ear with a paper clip, returning paper clip to stationary cup near phone.
-Nanny wearing husband's winter jacket and snow boots to exit and return to house, likely to walk child to bus.
-Nanny snooping through mail very thoroughly
-Nanny in multiple conversations on phone where she is angry and yelling (no audio, based on appearance only).

Most of the time this occurred falls in times when the children are in school. And I wasn't looking for anything about the nanny, but rather a repairman who we thought was responsible for stealing a check register. Anyway, it was more than I needed to see. We're changing the locations of the nanny cameras to face the front and back door and porch areas and foyer, so we can see who is coming and going.

The Tooth

This is driving me crazy. We hang out in the family room off the kitchen most of the time. Our family consists of two children, under four and my husband. We have a live-out nanny that works weekdays.  This morning we were enjoying a Saturday morning together. I was on the floor doing a puzzle when I noticed a small object under the sofa. I quickly grabbed it before one of the kids put it in their mouth. The problem is it is an adult sized tooth, and one that would come from further back in the mouth. I called my nanny and told her what I found and she said..."that's weird, it isn't mine". My husband and I literally checked our mouths to make sure our teeth were accounted for. As a mom who plays with her children on the floor and as a mom who makes sure there are no unsafe items on the floor, this tooth was not there last weekend. I am certain. I am really unnerved that this tooth is in the house and we don't know where it came from. I feel the need to find out, as in press the nanny on if she had any company, but I don't want to be accusatory. I don't think she would have since we live in a doorman building and our children are young and keep her quite occupied. Any suggestions? Anyone else have a strange object turn up in their house?
