A gateway is a network device that connects two different networks and enables communication between them. It translates data formats, protocols, or IP addresses to ensure systems can exchange information effectively.
For example, in surveillance networks, a gateway links local devices to cloud platforms or external monitoring centers. This connection allows remote access, system integration, and centralized control.
While routers handle traffic within a single network, gateways operate across networks with different architectures. They often include security features such as firewalls or VPN support.
By using gateways, organizations improve network flexibility, connectivity, and data security.
