The IR illuminators can be disposed below any portion behind the substantially opaque area. The IR illuminators are concealed under the front cover plate 708, but light generated by the IR illuminators can still penetrate the front cover plate 708 to illuminate the field of view of the doorbell camera 106.

For example, the Electronic Frontier Foundation has warned of a secretive surveillance tool being used by the FBI which acts as a face cellular tower. These devices, called Stingrays, lets the government search large geographical areas for a particular cell phone signal. In the process however, the devices collect information on thousands of other cell phone signals belonging to unassociated people, which happen to also be located in the same area.
