A surveillance camera is a video camera that is used to remotely monitor an area or building by transmitting recorded images to a central control room.
In military usage, surveillance cameras provide additional security in areas where it may be difficult to position a manned patrol unit, or used in tandem with a patrol to provide extra coverage. If a camera detects an anomaly, an intruder, or a disturbance, an alert is raised from the central control room, and personnel are dispatched to the area to investigate.
A surveillance camera was utilized in the hospital room that Naked Snake was recuperating/imprisoned in during the aftermath of the Virtuous Mission, namely to monitor what he is doing. However, the processing screen was choppy.
Although none were actually seen during the Peace Walker Incident, the surveillance room on the United States missile base in Nicaragua indicated that the U.S. missile base did indeed use them, with Snake using one to converse with locate and converse with Paz Ortega Andrade.
During the 1980s, the successor PMC to the Militaires Sans Frontières, the Diamond Dogs, included surveillance cameras on the forward operating bases on their Mother Base in the Seychelles near Africa, in an attempt to deter any intruders belonging to any competitors to the Diamond Dogs.
Surveillance cameras may operate continuously or only as required to monitor a particular event. During the Big Shell Incident, a camera of the latter type was set up in the Shell 1 Core of the Big Shell, in order to clear personnel for use of an elevator.
The Eastern European city's station utilized a surveillance camera to verify peoples identities, as evidenced by signs in Czech during Solid Snake's visit to Eastern Europe to locate Big Mama during the Guns of the Patriots Incident.
The gun camera, mounted with a heavy, rapid fire weapon, was also deployed in restricted areas, which automatically fired upon a detected intruder. They often act autonomously and were sometimes deployed within areas of high electronic jamming, in which a central control room couldn't be alerted via wireless data transmission.
Cameras have a fairly large blind spot directly underneath them that can be exploited to hide in; if the player presses against the wall and only moves under the camera while the beam is facing the other direction. Using chaff grenades will also disable cameras in the area for a short period of time, allowing them to quickly run past them. Cameras can also be destroyed in the 3D games. In Metal Gear Solid, cameras can be destroyed only by using the Stinger missile launcher or any other explosives (i.e. Nikita or C4). From Metal Gear Solid 2 onward, the player has the ability to shoot out cameras by going into first person view and firing any lethal weapon to disable the camera; tranquilizer rounds will have no effect. Passing through a camera's field of vision will not cause an alert if the player is successfully disguised as an enemy or is using stealth camouflage. If the player manages to shoot out 15 surveillance cameras in the Metal Gear Solid: HD Collection, they'll gain the trophy called "Bye Bye Big Brother."
In the 2D Metal Gear games, cameras could not be avoided by simply walking under them. The only chance the player has for evasion is to hide behind a wall or equip the cardboard box before it moved over him.
Surveillance cameras also make an appearance in Metal Gear Solid: Portable Ops in the hospital, research laboratory, warhead storage facility, power plant and silo entrance. However, they are only present in Extreme Mode.
Camera that monitors a fixed area in a cycle. Sounds an alarm if an intruder enters its visual field."
