How many PoE cameras can the DH-CS4226-24ET-240 connect?

The switch provides 24 dedicated 10/100Mbps PoE access ports for compatible cameras, intercoms, wireless access points and other powered devices. Ports 1 and 2 can supply up to 90W each, while ports 3 to 24 support up to 30W each. The total PoE budget is 240W, so the combined power requirement of all connected equipment must remain within the available budget rather than every port operating at its individual maximum.

What uplink connections are available on this cloud-managed PoE switch?

Ports 25 and 26 are Gigabit combo uplinks. Each numbered uplink provides a 10/100/1000Mbps RJ-45 interface and a 1000Mbps SFP interface, with the copper or optical connection selected for that combo port. This gives the switch two Gigabit uplink paths for connection to a recorder, router, aggregation switch or fibre network. Suitable SFP modules and fibre cabling are not stated as included.

Can the CS4226-24ET-240 be managed remotely through the cloud?

Yes. The switch supports cloud management through Dahua DoLynk Care, as well as local web and app management. Cloud functions include real-time network monitoring, device-status viewing, fault alarms, notifications and topology visualisation through supported LLDP information. Cloud access requires internet connectivity, account configuration and an appropriate supported platform. Local configuration and cybersecurity settings should also be completed before the switch is placed into service.

What is PoE Watchdog and how does it help a CCTV system?

PoE Watchdog monitors the status of enabled powered-device ports and can restart a failed PoE port when a connected camera or other compatible device stops responding. This may restore operation without an immediate site visit and can reduce maintenance time. The function must be enabled and configured correctly, and it cannot resolve problems caused by damaged cabling, insufficient power, incompatible devices, network loops or hardware failure.

How does the 250-metre long-distance PoE mode work?

Long-distance mode extends PoE and network transmission on supported access ports to a listed maximum of 250 metres, compared with the usual 100-metre Ethernet design limit. The port bandwidth is reduced to 10Mbps in this mode, so it should be used only when the connected camera's bitrate and traffic remain suitable. Cable quality, connector workmanship, power demand and environmental interference can affect the achievable distance.

Can this switch power high-consumption PTZ cameras or other Hi-PoE devices?

Yes, subject to the complete power calculation. Ports 1 and 2 support IEEE 802.3af, IEEE 802.3at, Hi-PoE and IEEE 802.3bt with up to 90W available per port. Ports 3 to 24 support up to 30W each. The overall PoE budget remains 240W, so high-power devices reduce the amount available for the remaining ports. Confirm device startup demand, cable length and PoE standard before connection.

What network-management and protection features are included?

The switch provides port-based VLAN support for up to 32 VLANs, DHCP client operation, IEEE 802.3x flow control, loop protection, PoE power management and remote port power control. It also supports an 8K MAC table, 15KB jumbo frames and a 4Mbit packet buffer. Electrical protection includes 8kV air-discharge and 6kV contact-discharge static protection, plus 4kV common-mode and 2kV differential-mode lightning protection.

What should I confirm before ordering the DH-CS4226-24ET-240?

Confirm the number of powered devices, their normal and startup wattage, required cable distances, uplink type, VLAN design, rack space and cloud-management requirements. The 24 access ports are Fast Ethernet rather than Gigabit, and long-distance mode reduces a port to 10Mbps. When ordering through Security Wholesalers, provide the camera and recorder models so the PoE budget, uplink design and expected aggregate traffic can be checked before installation.

Description

Product SKU: DH-CS4226-24ET-240

Product Overview

The Dahua DH-CS4226-24ET-240 is a 26-port Layer 2 cloud-managed PoE switch designed for CCTV, intercom, wireless and small-to-medium business networks. It provides 24 Fast Ethernet PoE access ports and two Gigabit combo uplinks, with each uplink supporting either RJ-45 copper or an SFP fibre connection. Ports 1 and 2 deliver up to 90W for compatible high-power devices, while ports 3–24 support up to 30W each within the total 240W PoE budget. DoLynk Care cloud management, network-topology visualisation, fault notifications and local web or app management simplify remote monitoring and maintenance. PoE Watchdog can restart an unresponsive powered-device port, while long-distance mode extends supported PoE connections to 250 metres at a reduced 10Mbps bandwidth. The metal 1U housing supports desktop or rack installation and operates from -10°C to +55°C. The 24 camera-facing ports are 10/100Mbps rather than Gigabit.

Key Capabilities

24 PoE Access Ports

Twenty-four 10/100Mbps RJ-45 ports provide network connectivity and power for compatible IP cameras, intercoms, access points and other PoE devices. The 240W total budget supports larger CCTV deployments when individual device requirements are calculated correctly.

Two Gigabit Combo Uplinks

Ports 25 and 26 each provide a Gigabit RJ-45 interface and a 1000Mbps SFP interface as a combo pair. This supports copper or fibre uplinks to a recorder, router, aggregation switch or wider network.

90W High-Power PoE Ports

Ports 1 and 2 support IEEE 802.3af, IEEE 802.3at, Hi-PoE and IEEE 802.3bt with up to 90W per port. They suit compatible high-consumption PTZ cameras and other powered equipment requiring more than standard PoE+ capacity.

DoLynk Care Cloud Management

The switch supports remote management through Dahua DoLynk Care, including real-time device monitoring, network-status visibility, topology display, fault alarms and notifications. Local web and app management are also available for configuration and maintenance.

PoE Watchdog and Loop Protection

PoE Watchdog can automatically restart a configured port when a connected camera becomes unresponsive. Loop protection identifies network loops and activates an elimination mechanism to help prevent broadcast storms and widespread network disruption.

250m Long-Distance PoE

Long-distance mode extends supported network and PoE transmission to a listed maximum of 250 metres. Port bandwidth is reduced to 10Mbps in this mode, so camera bitrate and traffic requirements must remain suitable.

Best For

Medium CCTV Systems: Powers and connects up to 24 compatible cameras through one centrally managed switch.
Warehouses and Factories: Supports long camera cable runs, remote monitoring and high-power PTZ connections.
Retail and Office Networks: Combines CCTV, intercom and compatible wireless equipment within a managed Layer 2 network.
Multi-Site Service Providers: Uses DoLynk Care to monitor switch status, topology and faults without attending every site.
Fibre-Linked Installations: Provides two Gigabit combo ports for copper or SFP uplinks to recorders and aggregation networks.

Why Choose the DH-CS4226-24ET-240

The DH-CS4226-24ET-240 offers more control and service visibility than an unmanaged 24-port PoE switch. DoLynk Care cloud management, topology visualisation, PoE Watchdog, loop protection and remote port-power control help installers diagnose common CCTV network problems without immediately visiting the site. Two 90W ports can support compatible high-power PTZ cameras, while the remaining 22 PoE ports provide up to 30W each within the shared 240W budget. The two Gigabit combo uplinks also allow either copper or fibre network connections. Available through Security Wholesalers, this model is best specified after calculating the complete PoE load and expected network traffic. Its 24 access ports are Fast Ethernet, so projects requiring Gigabit bandwidth to every connected endpoint should use a different switch.

Buyer Decision Tips

PoE Budget Tip: The 240W budget is shared across all powered ports. Add each device’s maximum and startup wattage rather than multiplying the individual port rating by 24, especially when using 60W or 90W PTZ cameras.

Bandwidth Tip: Ports 1–24 operate at 10/100Mbps, while ports 25–26 are Gigabit combo uplinks. Long-distance mode further reduces a supported access port to 10Mbps, so confirm camera bitrates and aggregate uplink traffic before installation.
