Closed Circuit TeleVision (CCTV) originally applied to the video systems that schools used to train multiple students or classrooms at on time. Although Closed Circuit TV still applies to this Remote Training application of video surveillance cameras, it now often refers to Camera Security applications.

However, CCTV is certainly still leveraged to broadcast video from one local or remote classroom or set to any number of local &/or remote classrooms & auditoriums. 

=> CCTV solutions often provide the following benefits:
- Theft Deterrence
- Incident Capture
- Evidence Playback & Analysis
- Perpetrator Identification
- Rapid & Easy Prosecution
- Recovery of stolen property
