IP cameras allow for remote access of surveillance footage from anywhere through internet access on mobile devices, while CCTV cameras only allow local access. IP cameras are easier to use than CCTV cameras as they store footage on hard drives rather than tapes, and have higher resolution images. IP camera security systems are smaller, easier to expand over a network, and have lower overall costs than CCTV systems. Additionally, IP cameras can support audio, while CCTV cameras cannot. In summary, IP camera security systems provide better access, usability, image quality, scalability and value compared to traditional CCTV systems.
