A complete CCTV system encompasses several components: cameras, wiring, storage for video footage (via cloud or digital video recorder), monitors, access control mechanisms, and system management tools.
Businesses often deploy CCTV systems to enhance security by monitoring critical areas continuously. This is particularly beneficial for large premises housing valuable assets or information.
Beyond mere video recording, CCTV systems can alert operators to any movement or activity within monitored areas, even during off-hours when premises are typically empty. Such alerts can signal potential intrusions or unauthorized activity.
Aside from surveillance and security monitoring, CCTV systems aid in identifying suspects and serve as a deterrent against intruders.
How CCTV Systems Operate
Interested in the workings of a CCTV setup? The process is straightforward, though it varies based on system type and components used.
Typically comprising cameras, lenses, monitors, and recorders, a CCTV system can be scaled to suit different surveillance needs. Cameras capture continuous images, which are then transmitted via cables or wirelessly (depending on system configuration) to a recording device. From there, the footage is displayed on monitors, allowing operators to view the images as video.
Depending on camera capabilities, they may feature functionalities like zooming, panning, and night vision, or specialized tasks such as thermal imaging or license plate recognition.
Broadly speaking, CCTV systems come in two primary types:
- Wired Systems: Cameras and other components are connected via physical cables.
- Wireless Systems: These systems operate over internet connections without the need for physical wires.
Each type offers distinct advantages based on specific surveillance needs and environmental considerations.
