===Other detection===
There are many other types of detectors that use various sensory modes to detect intrusion.
; Pressure plates
: Detects any unauthorized person stepping on the sensor zone. An active pressure plate is depicted in the [[HUD]] as a red mesh region across a pinch point. If the sensor is disabled, the mesh turns gray.
; Laser fences
: Detects any unauthorized person passing through the sensor wall. A laser fence is depicted in the [[HUD]] as a vertical array of horizontal red lines forming a detection zone between two towers. Most laser fences are initially harmless except for detection, but the [[Security AI]] can activate "lethal" mode under elevated security protocol. The laser fence will then cause damage (usually not lethal) to any unauthorized person crossing through, in addition to detection.
; Motion detectors
: Motion detectors detect any unauthorized person sprinting through the sensor area. Motion detectors will not detect anyone sneaking through the zone, but the zone is usually large. A motion detector zone is depicted in the [[HUD]] as a red circle around the detector. Motion detectors are blocked by solid objects in the same way as a [[Cameras|camera]]. The [[HUD]] display does not mark the blocked regions of a motion detector.
; Bio-Scan Field
: A Bio-Scan Field detects life signatures within a large area. The [[HUD]] depicts this as a blue fuzzy glow in the air. The field will trigger an alert if too many bio-signatures are detected; the usual limit is 1 signature at a time. If more signatures are detected, the detector raises a pending [[Security Tally]]. If the extra signatures leave the field before the end of the [[Turn]], the pending [[Security Tally]] is removed and the [[Security AI]] is not informed.
; Mines
: A mine is a kind of [[Motion detectors|motion detector]] that will trigger an explosion if an unauthorized person enters the sensor zone. It will detect intruders both sprinting and sneaking. The mine does not directly add [[Security Tally]], but the explosion is likely to be heard by many enemies.
All of these sensors (except mines) will increase pending [[security tally|Security Tally]] by one or more points when triggered. The [[alert status|Detected Status]] of the merc may be increased. When the Security AI is notified of a detection, it will usually send a guard to investigate; the guard's [[Alert Status]] will be raised to Suspicious.
