The covert operative primer on improvised proximity alert methods; on the fly set up and use of these security measures (to detect or deter intruders) with no special equipment, while occupying any given room.

LINER TRADECRAFT

The purpose of an improvised proximity alert system is to be instantly notified of the presence of human activity around and or inside a structure or otherwise enclosed space that you’re actively occupying.

Furthermore, these systems are made on the fly with only the items and equipment on your person and immediately within reach of the occupied space.

Nothing is safe if you poke at it long enough. There are always imperfections, workarounds, gaps and anything can be broken – all that can be done is increase how long a breach would take in an attack. The better the security, the longer that time is…

This type of real-time information can produce strategic advantages to use in a variety of scenarios.

    20 Improvised Proximity Alert Methods:

+ Tripwire to trigger a light switch, fire alarm, TV, radio clock, mobile phone, car key fob, etc.

+ Basic A-B tripwire to physically “trip” subjects while in forward motion

+ Request hotel concierge for you to be contacted immediately but discreetly if anyone asks for you

+ Glass cup or other hard object balanced on top of a interior door handle or window sill

+ Broken glass shards / crunchy food bits / candy wrappers spot spread on the floor of key walkways

+ Remove or disable lightbulbs in target areas to create an obstacle or enable a rewired light switch trap

+ Place “loud” plastic bags under doormats, rugs and overtly anywhere to be stepped on

+ Use a TV or other large appliance with the cord plugged in to use as a tripwire

+ If there’s any (smooth) stairs within earshot, coat them with cooking or motor oil, or water in winter (to ice)

+ Place a mobile phone with a motion alert app actively running in a key area

+ If you know the subject’s contact info, call or text them to manipulate or maneuver

+ Repurpose a building’s existing motion sensor unit as your own proximity detection indicator

+ Remove hinges of already insecure doors then close as normal for a subject to use

+ Cover the hard and already slippery floors of foot traffic stress points with hair conditioner and water

+ Use a Wi-Fi or Bluetooth connected device-to-device (mobile phone to laptop) remote security video system

+ Rearrange furniture in a pathway disrupting pattern (especially for non-illuminated areas)

+ Have a trained or highly reactive dog on-site

+ Rewire a light switch to electrically shock the subject upon activation

+ Rewire a light switch to cause an isolated or cascading electrical short

+ Rewire a light switch to turn on a strategically alternate outlet


Each method of alert is powered or activated by the target subject(s). The effect of each “activation” is intended to cause one or more of these results;


REDACTED LOCKER


These are effectively passive triggering mechanisms that detect or react to physical movement, for strategy and security.
