In businesses, surveillance cameras are used to monitor employees, customers, and merchandise to prevent theft, vandalism, and other crimes. They can also help businesses ensure compliance with safety regulations and monitor operations for efficiency and quality control. Additionally, surveillance cameras in businesses can provide valuable evidence in the event of incidents or disputes. Overall, surveillance cameras play a crucial role in enhancing security and surveillance capabilities for both homes and businesses.
