The '''City Scanner''', also known as '''Scanner Type I'''''Half-Life 2 Prima Guide'' and often referred to simply as '''Scanner''', is a lightly armored, flying security camera used by the Combine to monitor City 17's (and possibly other cities) residents. Its Synth counterpart is the Shield Scanner.

The City Scanner is equipped with a camera used to take photographs; the camera acts as the "eye" of the scanner, with the aperture occasionally moving, while the flash is mounted on top of its frame. The flash emitted when taking a picture can temporarily blind a person, even when not looking directly at the scanner. However, if not looking directly at the flash the blinding will be less severe and allow some vision. The flash also acts as a searchlight, which is used for illumination and can move in any direction.

Scanners are powered by a single Combine battery, which can occasionally be salvaged from a destroyed unit and reused for the HEV Suit. Scanners are lightly armored and can be destroyed easily by gunfire, impacting against walls or being hit by objects. A critically damaged scanner will usually attempt to kamikaze dive into its attacker, while spinning and emitting an alarm.

As the name implies, Scanners are generally used only in cities and are rarely encountered anywhere else. They are commonly seen patrolling City 17's Canals, searching for refugees. Other applications include reconnaissance and searching for wanted individuals. Scanners help by locating targets and alerting other nearby Combine units. During emergencies, Scanners can be mass-deployed in thousands from the Citadel, to perform a city-wide, and possibly out-of-city search such as when Gordon Freeman was detected in City 17.

The scanner has four front flaps that can move independently, with the camera in the center. This design can be seen in Dog's head, which appears to be made of the eye and three of the four flaps of a salvaged City Scanner.

*While the City Scanner started as a Synth under several Shield Scanner the scenes|variations that made their way into the Shield Scanner, Ted Backman and Dhabih Eng both worked on the Scanners concepts; the first ended up with the Synth version, the second the mechanical one, first known as "Combot".Development of Half-Life 2 game|''Half-Life 2'' leak

*As the Combot, the mechanical Scanner was to throw gas from its front, and fire from the small ergots on its two sides.

*The mechanical Scanner design was initially modeled after the shape and movement of a piranha.

*11 sound files found in the ''Half-Life 2'' leak files also indicate that the mechanical Scanner was to talk directly to people via prerecorded messages. Spoken by a robotic female voice, they include sentences such as "Citizen, do not move.", "You may proceed.", "Hold still for scan.", "Hands on your head." or "Violation has been noted.".Development of Half-Life 2 game|''Half-Life 2'' leak files

*In the ''Half-Life 2'' chapters ''Anticitizen One'' and ''"Follow Freeman!"'', the "npc_create npc_cscanner" console code spawns a Shield Scanner.
*Scanners are not directly met in ''Half-Life 2 Episode Two|Episode Two''; they are only seen on the route to White Forest.
