Sensor Arrays: Houserules

With Sensor Arrays explained, next up is what default packages they come with. To start with, let’s look at the lessons we can learn from SR4.

Now in SR4, Arsenal defined a Standard Vehicle Sensor Package on p105, but back then each type of vehicle had a specific sensor capacity so drones had less sensors than that. This changed in SR5, as explained only the maximum rating of the sensor array depends on the vehicle, each array can contain up to 8 sensors.

Mind you, that’s UP TO. In other words it’s still perfectly possible, and with factory arrays even rather plausible, that a drone can come with less than 8 sensors normally.

Another thing Arsenal noted is that the GM could allow different default sensor packages, which I refer to below as well. (It also actually noted a test for replacing a Sensor with another.)

The standard package came with 2 Cameras, 2 Laser Range Finders and 2 Motion Sensors. This allowed vehicles to check out both its front and back, quite useful given how pretty much everything can move in reverse and you want to know what’s coming from behind you.

So these are the things we can gather from Arsenal:

  1. Vehicles come with Standard Sensor Array loadouts, rather than with completely-customizable loadouts for free.
  2. Custom Loadouts are possible but by GM discretion.
  3. Drones may have less & different sensors (though in SR4 this was due to a rule no longer valid here).
  4. The standard packages keep both front and back in mind and are willing to double-up on a sensor for that purpose.
  5. The standard packages include laser range finders for distances, and cameras + motion sensors for vision.

With that in mind we can design custom sensor packages for multiple types of drones/vehicles.

Disclaimer: This only applies to the factory arrays, not for any new sensor array you buy yourself!

Player Advice: If you buy Vision Enhancements, consider only getting them for your front camera! That will be the camera used when firing after all.

Rule: Land-based vehicles come with 2 Cameras, 2 Laser Range Finders, 2 Motion Sensors, 1 Atmosphere Sensor, 1 Omni-Directional Microphone, almost no plausible alternative loadouts exist

Since vehicles are big and expensive, there’s no real reason for them not to come with a full sensor package. This is pretty much the Arsenal package, except that the Radar has been replaced with an Omni-Directional Microphone for hearing stuff nearby. The Laser Range Finders let you measure precise distances, which is needed for Autopilots and more. The Motion Sensors you need for blind spots near you, so you realize there’s someone next to you while turning. No headsup on that truck barreling your way though…

The two motion sensors could perhaps be replaced by a single one because honestly, there’s nothing in those that explicitly forbids 360-vision despite the car being partially in the way. You could always replace the second and the microphone for two directional microphones.

This package is everything a car should ever need to come with under any normal circumstances. The only possible exceptions are the luxurious cars, which might come with a MAD scanner instead of the Atmosphere Sensor. Of course a GM can always change their mind, but I myself would stick with this layout.

Rule: Land-based vehicles come with 2 Cameras, 2 Laser Range Finders, 2 Motion Sensors, 2 Omni-Directional Microphones

Basically the same as above, except for following the ‘car blocks motion sensor’ logic for the microphone as well so using two instead of a silly atmosphere sensor. In a car you don’t usually care about the outside after all.

Rule: Microdrones and Minidrones come with 1 Camera, 1 Laser Range Finder, 1 Atmosphere Sensor and 1 Omni-Directional Microphone, no alternativeĀ  loadouts available

Since these drones are really small and are designed to essentially look forward, such as the Fly-Spy with its insect shape, their sensor packages represent the fact they don’t bother looking back. This restricts them to 180-degree vision. The Atmosphere Sensor is useful for hazardous situations, and at their size an Omni-Directional Microphone would never be restricted.

Keep in mind these drones normally cost at most 2 grand. Even though the factory has a scale discount, there’s still no reason for them to put extra sensors on these. They’re enough for what they need to do, and there’s no need for all the extra fancy sensors normally. You want extra? Well good luck, there’s still 4 space left so go ahead and buy your own! We only care about the bottom line after all.

Rule: Small Drones come with 2 Cameras, 2 Laser Range Finders, 1 Atmosphere Sensor, 1 Omni-Directional Microphone, alternative loadouts replace Camera + Laser Range Finder

Already more expensive than the tiny drones, these drones come with double vision+distances because they’re big enough to actually run into trouble if they don’t look at what’s behind them. They still don’t normally come with additional espionage sensors, but if you really need one they do sell those at a price: Sacrificing the back-view for it. This is so there’s an actual price paid for the additional option, since it doesn’t cost you a single penny. Still has 2 spare Sensor slots to fill up though.

Rule: Medium Drones and Large Drones come with 2 Cameras, 2 Laser Range Finders, 1 Atmosphere Sensor, 1 Omni-Directional Microphone, 1 Motion Sensor, 1 sensor of choice (Cyberware, MAD, Geiger, Olfactory, Radio Signal or Ultrasound), alternative loadouts replace Atmosphere Sensor with a second sensor of choice

Since these are bigger and more expensive, they come with a full sensor package that can keep both front and back in mind. This package is almost identical to vehicles, with one exception: They’re equipped with a single Motion Sensor because at their size the single sensor plausibly can cover their entire surrounding area. (The same applies for the microphone if you compare it to the second possible vehicle-package rule.)

Since you don’t buy a drone like this unless it’s to be prepared for trouble, the spare sensor slot is filled up with a sensor of your picking, all six options being sensors you’d like for security. If you really want to push it and the GM allows it, you could even get a model that comes with 2 security sensors but without atmosphere sensor.

Rule: Watercrafts and Aircrafts follow Land-based Vehicle default packages

You want to keep it nice and simple, this will suffice.

Rule: Watercrafts and Aircrafts have near-free loadouts, barring GM-vetoes

Since these things are rather expensive and follow different dimensions than mere cars, it’s quite plausible that no default sensor packages normally apply, instead leaving it entirely up to the buyer. I’d personally avoid this for the cheapest ones, but for anything past 50 grand this seems quite logical. The GM veto is because there’s a limit to how obscure a loadout you can easily score from a factory / mechanic without raising red flags.

Rule: Upgrading & Replacing Sensors requires Availability test for parts, Hardware test

If you want to add/replace a Sensor in an Array, or upgrade a sensor with new audio/vision enhancements, this lets you easily and cheaply do so: You first have to buy the sensor or the required parts, where for Enhancements you face the Availabily as if you were buying the combination new (just like Missions has for upgrading ware). So say you got a Thermographic Vision camera (Availability 5+6 = 11), and you want to add a Smartlink (+4R) to it. This means your contact has to do an Availability test of 15R to get the parts that wouldn’t clash with the TV already in the camera.

The reason for the rising availability is so that buying in chunks doesn’t avoid availability restrictions. No free ride here chummer!

If you want to add/remove a Sensor to an Array (replacing = remove + add), you need to succeed in the following: Hardware+Logic[Mental](8, 1 hour). This is basically the same test as in Arsenal.

For adding extra enhancements to a Sensor, or removing one from it, you need to succeed in the following test for each enhancement: Hardware+Logic[Mental](Ratingx2, 1 hour). In other words, the more advanced the camera/microphone, the tougher it is to put the parts in, doesn’t matter how much is already in there because you still have to leave space for future upgrades.

Of course a Kit suffices for these, so with a Shop or Facility you get a Superior Tools bonus. So if you hire a mechanic to put 2 Vision Enhancements into your rating 3~4 Camera, they’ll take ~8 hours which costs…. 800 nuyen I think?_? Buying a fresh one with enhancements already installed would still require 4 hours of cost to replace the sensor so not really a gain there. Just suck up to your Decker/Rigger instead.
