Laser tripwire



Laser Tripwires are a security measure used by several Organizations, and they appear in all Deus Ex games.

These tripwires are usually placed in a doorway or another narrow space that gets a lot of traffic. On one side are laser emitters, and these lasers reflect off a flat surface and back into the emitters. If a person "trips" the wire, the emitter will sense that an entity is blocking the laser, and it will trigger some form of consequence, such as drawing guards and bots to the location, or releasing poisonous gas.

Deus Ex
There are two varieties of laser tripwire:
 * Blue Tripwires - Blue ones rather deploy a security bot, usually Chiang Arcbot M2s or 100101 small security bots.
 * Red Tripwires - Red ones trigger an alarm, similar to Security cameras.

Lasers can be disabled through directly hitting the emitters with an explosive or stopping the associated power box with Multitools. The player can also place physics objects, such as metal crates, or a cloud of Pepper spray in front of the emitter to pass by without tripping it.

Deus Ex: Invisible War
In Deus Ex: Invisible War, there are 4 types of tripwires:
 * Red Tripwires - Combination of the Red and Blue wires from the first game. Red tripwires now call alarms and release bots if any are nearby.
 * Green Tripwires - Once tripped, release a tank of poisonous gas. The tank is usually found near the laser, and can be destroyed to neutralize the trap.
 * Yellow Tripwires - Cut through anything that passes through the laser. According to a scientist at Tarsus Seattle, they can kill someone in under 1/4 of a second.
 * Glass Sensors - Lasers running through panels of glass. Once the glass is disturbed, an alarm is set off, deterring intruders from breaking windows. The Glass Destabilizer weapon mod vaporizes glass, silencing the sound of glass shattering and shutting off any alarms the window may be rigged with.

These lasers can be stopped through physical obstruction, explosives or Multitools, like in the first game, although now they can also be disabled through EMP grenades and hitting the emitter with a melee weapon, if the player has the Electrostatic Discharge augmentation.

Deus Ex: Human Revolution

 * Red Tripwires are seen in Human Revolution, here they move back and forth, instead of the wires in previous games, which were always stationary.
