always depends. Low level ware house maybe a couple ferret drones, some rent a cops with pistols, and armored vest, with a panic button in the security office to call the cops. Maybe some rating 2 or 3 mag locks. A couple external cameras.
A Medium security, add more guards, maybe with some shot guns, nissan dobberman drones,with ARs, or SMG. a couple of flyer drones. Sub machine guns for the guards maybe. Rating 4 mag locks, RFID scanners, keycards. Panic button to call in a SRT team.
Seeing a tend here?
As far as cameras go, you have to think the almost over abundence of pics tures and information, you could have a agent sort through, but how many "Medium height, medium build, human, casusain male, wearing smart glasses" will they have to track down sift through and interrogate. As far as over head drones, in my experience over head ISR is not all its cracked up to be. "You mean we are looking for another, white datsun pick up truck, with a lugauge rack?". Worst comes to worst depending on how your getting in, and your infil plan just buy a damn ski mask.
