DH-CS4218-16ET-135-V2 18-Port Cloud Managed PoE Switch

The DH-CS4218-16ET-135-V2 is a smart, cloud-managed network switch designed for reliable connectivity and efficient power delivery to compatible network devices. Featuring 18 network ports, including 16 PoE ports, this switch provides a practical networking solution for CCTV surveillance systems, IP cameras, access points, VoIP equipment, and other Ethernet-connected devices.

With support for PoE standards including IEEE 802.3af, IEEE 802.3at, Hi-PoE and IEEE 802.3bt, the switch can deliver power and network connectivity through compatible Ethernet cables, helping simplify installations where separate power connections would otherwise be required. The total PoE power budget is up to 135W, while Ports 1 and 2 can support up to 90W each and Ports 3–16 support up to 30W each, subject to the overall power budget and connected-device requirements.

16-Port PoE Connectivity for Network Devices

The DH-CS4218-16ET-135-V2 provides 16 × RJ45 10/100 Mbps PoE ports for connecting compatible powered devices. It also includes two combo uplink ports supporting 10/100/1000 Mbps RJ45 or 1000 Mbps SFP connections, providing flexible options for integrating the switch into different network infrastructures.

This makes the switch suitable for installations that require multiple IP cameras or other PoE devices to communicate through a central network point. The combination of PoE connectivity and Gigabit uplinks helps create an organized and scalable network layout.

Intelligent PoE Power Management

The switch supports intelligent PoE power management, allowing network administrators to manage PoE power consumption and control PoE power on individual ports. This can help simplify the management of connected equipment and provide greater control over the overall network installation.

The built-in PoE Watchdog feature can monitor connected PoE ports and automatically restart a port when a connected device experiences a communication problem. This is particularly useful in surveillance environments where maintaining connectivity with network cameras is important.

Cloud and Web Network Management

The DH-CS4218-16ET-135-V2 supports web-based and cloud management, giving administrators convenient ways to configure and monitor the network. Dahua also lists centralized cloud management through DoLynk Care, together with real-time network monitoring and network topology functions.

Cloud management can be useful for installers and system administrators handling network equipment across different locations. Instead of relying solely on local access, compatible management tools can make network monitoring and maintenance more convenient.

VLAN and Network Control

For installations where network traffic needs to be organized, the switch supports VLAN functionality. It provides IEEE 802.1Q VLAN support, with up to 32 VLANs listed in the specifications. Additional network features include flow control, loop prevention, port isolation, multicast storm control, broadcast storm control, unknown unicast suppression and port mirroring.

These features make the switch suitable for structured networking environments where traffic management and network organization are important.

Long-Distance PoE Transmission

One of the useful features of the DH-CS4218-16ET-135-V2 is its long-distance PoE transmission capability. In extended transmission mode, compatible PoE connections can reach distances of up to 250 metres at 10 Mbps, depending on cable quality, connected-device power requirements and installation conditions.

This can be valuable for larger CCTV installations where cameras or other PoE devices are positioned far from the main network equipment. Actual performance and available power should always be considered when planning long-distance installations.

Reliable Performance for CCTV and Networking

The switch operates as a Layer 2 smart managed switch with a switching capacity of 7.2 Gbps and a packet forwarding rate of 5.36 Mpps. It has an 8K MAC address table, a 4 Mbit packet buffer and supports jumbo frames up to 9216 bytes according to the listed specifications.

The unit is housed in a sheet-metal casing and supports both desktop and rack installation, making it adaptable to different equipment-room and networking setups. Its operating temperature range is approximately –10°C to +55°C, with non-condensing operating humidity specifications suitable for many indoor networking environments.

Suitable Applications

The DH-CS4218-16ET-135-V2 can be used in a range of professional networking applications, including:

• CCTV and IP surveillance installations
• Multi-camera security systems
• Offices and commercial buildings
• Schools and institutions
• Hotels and hospitality facilities
• Shops and retail premises
• Warehouses and industrial facilities
• Networked access points
• VoIP and other compatible PoE devices
• Structured Ethernet installations
