The Hollywood Hills rental home where singer D4vd was living has a security system with external cameras that capture everyone going in and out ... the owner tells TMZ. The homeowner says the cameras are positioned at entry points, in the backyard and on the street ... and he believes people can not go in or out of the house without being recorded. That's a key element because cops were looking into the possibility that Celeste was killed inside the home ... as we first told you, investigators searched the home for traces of blood. The landlord says LAPD has not told him anything about the investigation or if cops obtained security footage ... but he doesn't see why police wouldn't get their hands on the video.
