The invention disclosed herein concerns a privacy enhancing device for use with IP cameras and related methods. The privacy device includes an adjustable light filter and is configured to be placed over the lens of an IP camera such that the image captured by the IP camera passes through the filter. The transparency of the light filter is controlled using a control module in response to user inputs received using an on-board user interface so as to provide varying levels of privacy ranging from an opaque state and a transparent state. Inputs that serve to facilitate and enhance operation of the device can also be received from other input sources such as connected computing devices. For security, the control path defined by the control module and the on-board user input device can be isolated from other more sophisticated control devices that can be prone to hacking and remote control.
