Any recommendations for 'discreet' wifi front door security cameras?

[Siwsan]

25. I'm looking into a motion detecting security light for my back yard

And I do have iron bars in the tracks of the sliding windows and door, and security flip locks on the entry doors and even the basement door. The new windows I had installed all of little security flip bars that only allow the windows to be open about 2 inches.

My whole security search was triggered by the return of my 'quasi-stalker'. I've told her, up front and in no uncertain terms, and for many, MANY legitimate reasons, to leave me alone and to stop pestering my family to intervene but every few years she starts up, again. Before I moved and changed my phone number, she'd watch my coming and going, send me drippy letters and call, crying that she misses me. I don't think she's dangerous or a threat to anything other than my mental health but any contact will just start the whole thing over, again.

This individual has now enlisted her son in her quest to get back in touch. I've had to block him and his sister on Facebook. He has a history of what we will call bad behavior, in his younger days. He might, now, be a stellar citizen but I watch far too much Discovery ID TV shows and know situations like this can take a bad, unexpected turn.

Hope you forgive my 'over sharing'!
