Ring cameras. Gave me peace of mind while away from home and caught my landlord entering my apartment unannounced once while I was away. Gave one to my parents, who reluctantly accepted it. Caught and deterred would-be burglars entering their house 2 months after setting it up. I used to manage my parents' old-style security cameras, and now I realize what important features they lacked. It takes a lot for a system to catch people in the act, regardless of how high-quality your cameras are and how much disk space your DVR has, and convenience matters too.
