Drones as opposition/security, How common are they in YOUR games? Options

[Brainpiercing7.6...]

I have a problem: When designing security as the GM, I often forget just how CHEAP drones are now. Basically, for every human guard with just a modicum of training and equipment you can get two drones, which then cost basically nothing much, while the guard keeps eating wages.

Then there is the issue of how to control them: A drone on pilot is pretty piss poor at everything, unless you invest in a good pilot program, autosofts, etc. So, a drone wiht a DP of 6-8 isn't much good at actually killing stuff, and they also won't be able to make many "smart" decisions. On the other hand, they should be able to spam a lot of lead, which generally takes care of hitting issues.

I still feel that probably i'm not using them nearly enough. I use them for colour, and basically as mobile camera systems, where I should be spamming then. Then there is the issue of how to control them. As I said, on pilot they aren't that dangerous. With a jumped in rigger this can change pretty quickly (if their sensor packages are good enough). Then there is the problem of how secure to make the networks that run them. It seems to me that if security is too light, then you basically just gave your runners a present of a multitude more guns and eyes on their side. But realistically, what numbers should a drone network have?

So, my questions:
How do you avoid this issue? Is using drones second nature to you? What is your ratio of human guards to drones? How many of them are flying about in your everyday city sky, or rolling around in your everyday city streets? How scared are your NPCs of drone theft, or rather, how scared are you that your PCs will just see ubiquitous drones as an invitation to lining their pockets? How secure are your police or corporate drone networks?

And of course, how do you configure opposign drones? Are they customized or do you deploy them basically straight from the book?
