What is the common application of using a Dynamic Host Configuration Protocol in surveillance systems?

Using Dynamic Host Configuration Protocol (DHCP) in surveillance systems primarily serves the function of automatically assigning IP addresses to devices such as cameras, recorders, and other networking equipment. This automatic assignment simplifies the configuration process for networked devices, ensuring that they can quickly and efficiently join the network without requiring manual IP address settings.

In a surveillance context, where numerous cameras may be deployed, manually setting IP addresses can be cumbersome and prone to error. By leveraging DHCP, administrators can streamline the setup and management of camera systems, enabling the devices to obtain their IP addresses dynamically and reducing configuration time.

The other options, while relevant to various aspects of surveillance systems, do not pertain directly to the primary purpose of DHCP. For instance, while networking multiple cameras relies on appropriate IP addressing, that function is inherently tied to DHCP. Storing video footage is handled by storage solutions, and securing communication protocols relates to encryption and cybersecurity measures rather than IP assignment processes.
