Security

Stage 0
Stage 0 is a most basic state of security, with little to nothing in the way of security features. Little will occur if an intruder enters the area. Little to no preparedness for emergency or disaster has been undertaken.

Stage 1
Stage 1 security level includes a basic suite of automated sensing systems covering at least major points of entry and vehicle movements, some considerations for defensibility such as creating clear line of sight on area surrounding habit, and a mild active deterrent such as a motion-tracking spotlight. An intruder entering the area would be hit with bright light and an audible warning, and residents and/or local authorities would be notified. A small reserve of emergency rations, first aid equipment and other supplies is also specified, as well as fire suppression equipment such as an extinguisher.

Stage 2
Stage 2 security level is a substantive platform of active defense featuring an area denial system in the form of one or more turreted semi-automatic computer controlled rifles firing lethal or non-lethal ammunition. A computer data hub monitors a 360 degree area around the defended structure with visible and infrared cameras. Object tracking maintains lock on the target(s) and directs the turret using laser range finding and other methods. A safe zone of some kind such as a concrete basement with barred steel door exists in the structure to provide a fortified emergency shelter should a dire situation arise, with included extensive provisions, additional first aid supplies and heavier duty fire extinguishing device. An intruder encountering a Stage 2 secured structure would be warned audibly, painted visually by spotlight, and should they not heed the audible warning and stop approaching, they would be fired upon, initially a warning shot at the feet, followed by repeated hits with nonlethal munitions. Lethal strikes would require resident authorization to prevent accident.

Stage 3
A military or paramilitary force is required to neutralize defense stage 3. Additional structural fortifications such as armored walls and windows, air supply scrubbers and chemical filters, and fire suppression systems augment the security of the structure. Hardened electronics may also be featured. Drones may be used on automated patrol routes and timings to maintain a much larger field of awareness. At least 2 weapon turrets with at least one large caliber anti-material rifle such as a .50 BMG provide active defense against personnel and non-armored vehicles out to a 1+ mile range. Provisions are made for mid to long term survival with little to no access to food or water, extensive medical equipment is stocked, and the structure is equipped with a sprinkler system for fire suppression.

Automated Hunting
Should the resident(s) be of the moral persuasion, an automated hunting system could be enabled at Stage 2 or higher to provide a free source of meat. An alarm would be triggered to resident upon firing so as to facilitate rapid collection of carcass.
