That very same evidence could also have been used as blackmail and extortion material. Those secret recordings could have been done using both audio and visual equipment.
Other devices that could have been used to record their conversations during meetings with the Guptas could have been their cellphones.
Cellphones can also be turned into transmitters, whereby they can relay (transmit) private and confidential conversations (dialogues).

Electronic equipment that could have been used include television sets, wall clocks and microchip bugs planted inside portable accessories like pens, glasses, cigarette lighters, packs of cigarettes, car keys, and watches.
The saying “I wish I could have been a fly on the wall in that particular meeting” applies here.
