The other day I was touring a home with some buyers when I noticed a camera on one of the book shelves. The camera was on but I didn’t see the little blinking green light so it may not have been recording but there could have been someone watching through the interent. Hard to tell.
These cameras are popular as baby monitors and can be set up as motion detectors that will send an email to the owners who can activate an app on their tablet or smart phone or use a computer to get the same view the camera is getting. They are becoming more common.
In other words a homeowner could be away and watching people inside their home and listening to what they have to say. The cameras can see and hear, zoom in or out and pan the room.
I have to admit I would be tempted to watch if it were my home being toured by potential buyers. We use cameras instead of an alarm system.
This picture is coming from a camera placed near the ceiling on a cabinet. It automatically adjusts to gray scale in low light situations so that it even works in the dark.
