The device that is used to add audio capabilities to cameras without native audio functionality is the T61 Portcast Device. This device acts as a bridge, allowing audio to be transmitted alongside video feeds, enhancing the surveillance capabilities of cameras that do not originally support audio recording or streaming. It essentially expands the functionality of existing camera systems by integrating audio input from various sources.

The other choices do not fit this purpose. Axis Site Designer is a tool for designing and planning installation layouts of video surveillance systems, rather than providing audio functionality. A Network Time Protocol Server is crucial for synchronizing time across devices in a network but does not deal with audio capabilities. MAC Address Switches are components used in networking to manage data traffic based on device addresses, and again, have no relevance to adding audio to cameras. Hence, the T61 Portcast Device stands out as the correct choice for enabling audio features in such scenarios.
