Legal Question in Civil Rights Law in California

It can be argued that it is legal because the owner wants to protect the property. At the same time, I can see your view that since you are renting the premises, you should have a right to your privacy and the camera's presence is creepy. I would suggest speaking with the owner about disabling the camera for the living room or, if your rental agreement is silent about it, throwing a towel over the camera while you are there while making sure not to damage it.
