Traditionally analogue CCTV is installed using co-axial cables consequently these systems are low resolutions and have no image processing capabilities.
TVI is a method of transmitting a HD analogue signal down the old type cables. Although these images are better than the old analogue cameras they are still in effect been transmitted in analogue down the old type coaxial cables. In addition to the signal being transmitted along the old type of cable the TVI technology has no image processing capabilities which means the colours are inferior. The resulting image is prone to shadows caused by interference getting on to the co axial cable.
The systems we install are IP (internet protocol) systems, this means they’re not TVI. They are wired in CAT5e external grade solid copper cabling which enables our systems to run at gigabit bandwidth speeds. These type systems are true digital. The higher bandwidth allows us to transmit higher resolutions at far superior quality that a TVI analogue system simply cannot complete with. IP cameras do all the image processing within the camera before it is sent back to the control down the superior cable.
The end result is a crisp and clear image not forgetting the beautiful vibrant colours. CAT5e cabling bandwidth is that fast, it can simultaneously transmit 167 4K 8 megapixels down one cable! This makes it the obvious choice when installing CCTV as it future proofs the infrastructure of your system. Click HERE for more information on pixels and megapixels.
