I am interested to know the range of any of the security cameras. When I search for 'range' I find only the range of wifi from the hub so maybe I am using the wrong word. I am just trying to find the range that the cameras can cover (in meters or feet) from the eye of the camera to the object which is being looked at / filmed. What is the maximum? I've checked the specs of a camera I'm interested in but can't find any info about this but I'm sure it's there somewhere! As for the model, I was thinking about the 'Stick Up Cam Battery' but any will do if they are the correct range.
