Inter-Spectral Vision

Inter-Spectral Vision was an item which was acquired and utilised by a Dalek as it fought to escape the Vault, enabling it to detect cloaked human security officers and mines. (NOTVALID: The Last Dalek)

Behind the scenes
The Inter-Spectral Vision was identified in the video game The Last Dalek, based on the television story Dalek. It was acquired in Level 7.

In the original episode, however, the Vault's security personnel were not shown to use cloaking technology. As such, no mention was made of the Dalek's enhanced vision.
