Emitters are security measures which emit laser beams. Depending on the type of Emitter, it is either impossible for an agent to walk through the beam, or there is a penalty for doing so. The type of emitter depends on the corporation the facility belongs to.

Each Emitter is connected to a Power Supply which can be hacked or rebooted to disable or control the emitter. Emitters cannot be directly hacked as they do not have firewalls, but they can be rebooted using EMP Packs. Additionally, an Emitter is always disabled when a guard is in the beam, even if the guard is knocked out or dead, or a drone under the agency's control.

Every facility has exactly one Emitter along a 2–4 tile boundary which connects two rooms, except for Security Dispatch and Vault missions which have an additional emitter protecting the objective room, and the Tutorial mission which has none. Except for emitters protecting objective rooms, there is guaranteed to be an alternative route between two rooms connected by an emitter which does not require disabling the emitter or going through it.

Beam Emitters emit non-lethal laser beams which agents can walk through, but if they do, the alarm level is raised by 1 step. They appear in FTM and Plastech facilities.

Laser Panels emit lethal laser beams which agents cannot walk through. If the Power Supply connected to a Laser Panel is hacked, then it can be enabled in order to block guards' paths.

If an enemy-controlled Laser Panel is temporarily disabled, but then becomes enabled again while an agent, Courier or Prisoner is standing in the beam, it deals lethal damage to them. If an agency-controlled Laser Panel is enabled while a guard stands in the beam, it kills the guard, and then the Laser Panel is rebooted for 6 turns.

Infrared Emitters emit non-lethal laser walls which agents can walk through, but if they do, a random daemon is triggered and then the Infrared Emitter is disabled for the rest of the turn. They appear in OMNI and Sankaku facilities.
