Dahua SG4028

Equipped with a high-performance switching engine, the 28-port all-gigabit managed switch performs optimally. It has low transmission delay, a large buffer, and is highly reliable. It also has strong switching capability and optimizes transmission performance when accessing Ultra HD videos. With its full metal design and fanless construction, the device offers excellent heat dissipation and low power consumption, operating in environments ranging from -10°C to 55°C (14°F to 131°F). With protection against overvoltage, EMC, and overcurrent from power input terminals, the switch effectively resists interference from static electricity, lightning, and pulses. It also features powerful network management functions, supporting IGMP snooping, link aggregation, QoS, LLDP, STP/RSTP, and web management.

Link aggregation combines multiple physical links into one virtual channel for dynamic redundancy and load balancing, ensuring that the connection remains stable.

Quality of service (QoS) uses mechanisms designed to control bandwidth, delay, jitter, and loss to ensure the performance of services when capacity is limited.

Link layer discovery protocol (LLDP) enables network devices to advertise their information mutually, allowing for convenient monitoring and management of devices in the local topology. This makes it easy for administrators to effectively perform troubleshooting.

Spanning tree protocol (STP) uses algorithms that calculate the best loop-free path through a Layer 2 network while providing path redundancy to prevent the occurrence of broadcast storms and enhance the stability of operations and services.

IGMP snooping listens to multicast traffic and solely forwards information to registered clients based on the multicast forwarding table. This ensures the safety of information and improves network efficiency.

The fanless design reduces noise, enhances user experience, reduces mechanical losses, and improves service life to a certain extent.
