The number of CCTV cameras a UK house needs depends on the property's size, layout, and security objectives. A typical recommendation is to cover key entry points, such as front and back doors, and strategic areas like the driveway, main living areas, and back garden. A small to medium-sized house may require 4-6 cameras for comprehensive coverage. However, larger properties or those with unique features may need more cameras. It's essential to conduct a security assessment to determine the ideal camera placement and quantity to meet your specific needs.   For businesses, the number of CCTV cameras required can vary significantly based on the size and nature of the establishment. Small businesses might suffice with 4-8 cameras, focusing on entrances, cash registers, and main areas. In contrast, larger commercial properties, warehouses, or manufacturing facilities could require a more extensive network of cameras, potentially needing 16-100+ cameras. The exact camera count depends on the business's security priorities, layout, and surveillance goals, making a professional security assessment essential to determine the optimal camera quantity.
