Elevate your network infrastructure with the Dahua CS4220-16GT-135-V2, a sophisticated Layer 2 managed PoE switch designed to provide a robust and intelligent foundation for your most critical systems. Engineered for reliability and high performance, this switch is the ideal solution for businesses, security integrators, and IT professionals seeking to power and manage a wide array of network devices, especially within demanding video surveillance environments. It delivers a seamless combination of high-speed gigabit connectivity, substantial power delivery, and advanced management features to ensure your network operates with maximum efficiency and uptime.
Experience unparalleled convenience and cost savings by consolidating data and power over a single Ethernet cable. With a generous 135W total PoE budget, this switch effortlessly supports a full suite of IP cameras, VoIP phones, wireless access points, and other PoE-compatible devices, eliminating the need for individual power adapters and complex wiring. Its intelligent power management capabilities ensure that connected devices receive stable and reliable power. For high-power devices like PTZ cameras, the switch offers Hi-PoE support on dedicated ports, delivering up to 60W for uncompromising performance. Furthermore, its innovative long-distance PoE transmission technology extends your reach up to 250 meters, providing incredible flexibility for deploying devices in large facilities, warehouses, or campus environments without signal degradation.
Take complete command of your network with a rich set of Layer 2 management features. The Dahua CS4220-16GT-135-V2 empowers administrators to optimize traffic flow, enhance security, and simplify troubleshooting through an intuitive web-based interface, command-line interface (CLI), or SNMP integration. Implement VLANs to segment your network for improved security and performance, and use Quality of Service (QoS) to prioritize critical data traffic, ensuring smooth video streams and clear voice calls. The groundbreaking PoE Watchdog function automatically detects unresponsive devices and reboots them, dramatically reducing downtime and minimizing the need for manual intervention—a crucial feature for maintaining continuous security monitoring. Built for resilience, it also supports network redundancy protocols (STP/RSTP/MSTP) to prevent network loops and ensure a stable connection path.
