Nanobug
Nanobug (TL9)
A pinhead-sized sensor/recorder unit (SM -18) with an adhesive backing, which is usually placed somewhere where it can scan an entire room. Its camera and microphone can record constantly, listen for a specific voice before recording, scan at specific times of day, or scan when its sensors detect light or motion in the room. It includes a microcommunicator that can transmit recorded data in a short "burst" upon receiving a coded radio command. It can also be set to transmit after a specific time has passed. Once it transmits, it may be programmed to erase everything it has stored and begin recording again, or to self-destruct. It will also self-destruct if tampered with (roll vs. Explosives (EOD)-3 or Traps-3 to defuse). $100, AA (1 year), LC3 (presumed, not given in the book).
Emissions Nanobug (TL9): As above, but instead of audiovisual sensors, it has field-emission sensors that can read data being sent to or from an electronic device that the bug is in direct contact with. It cannot read stored data that is not being accessed.
Microbot Nanobug (TL10): A single, tiny microbot spy (SM -16). As a regular nanobug, above, but add any microbot swarm chassis at 1% the usual cost. Mobility is as per a cyberswarm. One hit destroys it.
