If you’re looking at CCTV installation North Wales or CCTV installation Pwllheli then its best to understand more on what it means, and how it all works. Speaking to a specialist can help determine the perfect system for you. 

CCTV stands for ‘Closed-Circuit Television’. This is a closed-circuit system, meaning that the signal is not openly transmitted (or openly shared) like it is with broadcast television. The video cameras only share the footage back to the monitors it is linked to. 

CCTV is a video method where cameras are specifically placed to record video images, and have these sent back for viewing to a monitor, or monitors, with only a small number of people able to access the footage. The system will consist of a monitor, a recorder, a camera and a lens. The cameras picks up the images, which are then sent to the recording device, and lastly to a monitor.
