Traditional analogue CCTV systems
​Traditional analogue CCTV systems use coaxial cables to transmit video signals. As a result, image resolution is limited and there is no built-in image processing. While these systems were once the industry standard, they lack the clarity, colour accuracy, and performance expected from modern surveillance solutions. With advancements in technology, analogue CCTV has largely been overtaken by more capable digital alternatives.
HD analogue CCTV (TVI technology)
TVI technology enables high-definition analogue signals to be transmitted over existing coaxial cables. This offers a noticeable improvement over older analogue systems and can achieve resolutions of up to 4K (8 megapixels). However, TVI signals are still transmitted in analogue format and rely on legacy cabling. Because TVI cameras have no onboard image processing, colour accuracy and overall image quality do not match that of IP systems. While TVI remains a viable upgrade option where existing cabling is in place, it cannot fully compete with true digital CCTV technology.
​IP CCTV systems – true digital surveillance
IP (Internet Protocol) CCTV systems are fully digital and deliver superior image quality. These systems are installed using CAT5e external-grade solid copper cabling, allowing gigabit bandwidth speeds. The increased bandwidth supports much higher resolutions and significantly better image clarity than TVI analogue systems. IP cameras perform image processing directly within the camera before transmitting data back to the recorder, resulting in sharper detail and more accurate colours.
