Summary

The Security Cameras can be seen throughout the Test Chambers within the Aperture Science computer-aided Enrichment Center. Throughout the Portal series, the cameras are used by GLaDOS as a means of monitoring the movements and progress of Test Subjects.

While it doesn't serve any vital role in-game at least in Portal and Portal 2, cameras in Portal are referred to as 'vital testing apparatus' if destroyed.

Also included is a fun turret version! The holes are sized for 9mm wires to connect the back of the camera to the wall mount!
