Numerical CVI Security cameras (Composite Video Interface) is a high-definition analog video signal used in security cameras. It was developed by Dahua Technology in 2014 as a cost-effective alternative to IP cameras for high-definition video surveillance.
CVI technology allows transmitting high-definition video over coaxial cable, similar to traditional analog CCTV systems. However, CVI cameras can send video at resolutions up to 1080p or 4K. Providing much higher image quality than traditional analog CCTV cameras.
Numerical CVI Security Cameras are also capable of transmitting audio. And data signals over the same coaxial cable, reducing the need for additional cabling and simplifying installation. Additionally, CVI cameras can be used with existing analog CCTV systems. Allowing for easy upgrades to high-definition video surveillance without the need for a complete system overhaul.
Moreover The depth of field is determined by several factors. Including the aperture of the camera lens. The focal length of the lens, and the distance between the camera and the object being captured. A camera with a larger aperture (lower f-stop number) will have a shallower depth of field. While a camera with a smaller aperture (higher f-stop number) will have a deeper depth of field.
Overall, CVI technology provides a cost-effective and easy-to-install solution for high-definition video surveillance. Offering the benefits of IP cameras at a lower cost and with more excellent compatibility with existing systems.
