CCTV: Understanding Modern Surveillance Technology
Traditional CCTV vs Modern Systems
What does CCTV stand for? The term CCTV (Closed Circuit Television) traditionally referred to analogue surveillance systems operating on a self-contained network. These systems consist of cameras connected via dedicated wiring to recording equipment and monitors, with all footage stored on-site in a truly ‘closed’ circuit.
The Evolution to IP Technology
Modern surveillance has largely shifted towards IP (Internet Protocol) camera systems, which offer significant advantages:
- Superior image quality
- Enhanced features and capabilities
- Remote access functionality
- Cloud storage options
- Greater flexibility in system design
Today’s Definition
While IP-based systems technically operate differently from traditional closed-circuit systems, the term ‘CCTV’ has evolved to encompass all types of video surveillance technology. This broader definition reflects how the industry has adapted to technological advancement whilst maintaining familiar terminology for users and providers alike.
The key distinction lies in how these systems process and store data:
- Traditional CCTV: Operates within a closed network with on-site storage
- IP Systems: Functions over computer networks with potential cloud storage and remote accessibility
Despite these technical differences, both systems serve the same fundamental purpose of providing effective video surveillance for security and monitoring needs.
