Passive Sensor Net, REALLY annoying runners... Options

[The Jopp]

So, how do we make a cheap and reliable shadowrunner detection system?

RFID tags

RFID tags have a signal of 0 which gives a range of 3 meters and a sensor package of 1. Let us assume that with the advances of superconducting materials and battery life these things can function for at least a few years before degrading. We also put all of them in hidden mode.

1 RFID tag cost 1Y which mean that a corporation can shell out say…100K on RFID tags, get a 30% cost reduction for bulk purchase.

Now we come to the sensors.
Barometric Sensor [Measures Pressure Changes]
Motion Sensor
Thermometric [Measure Heat]
Microphone

Insert RFID tags all over the mesh in buildings just below the:
- Floor
- Walls
- Ceiling
- Doors/Windows

Let’s assume 30% cost reduction for bulk purchased and skip VAT cost and suchlike.
70K one hundred thousand RFID tags
350K for twenty-five thousand Thermometric Sensors
0,468750K for twenty-five thousand R1 Barometric Sensors
0,875K for twenty-five thousand R1 Microphones
0,875K for twenty-five thousand R1 Motion Sensors

Total: 2.638.750,00Y

Two and a half million Yen isn’t expensive for a company who are concerned about security adding 100.000 sensors in a building.

Each floor have barometric RFID tags inserted just below the linoleum floor detecting pressure changes.
Microphones are hidden in ceiling and walls.
Motion sensors are scattered close to windows and doors
Thermometric sensors are built into doors and each and every handle of the building.

These might be low grade rating 1 sensors, but there are 25.000 of each type.

All of them report individually through a network that can ONLY receive RFID tag sensor data information, you need to break into the hardware to reprogram it.

The information center link all the reports together to form an “image” of movement through the building and report any changes within.

The more sensor hits the center receives the higher priority the alarm gets.

Information centers might hidden within the walls as well and function as a hidden network connected through the building with fibreoptic cables – thus almost impossible to find.

Add two security guards with a yearly income of 30K a year (slightly above low lifestyle) who have a hand-held receiver that can receive the same information as the center gains from the sensors – adding a human security decision (albeit cheap).
