24 PoE PORTS · 240W · CLOUD MANAGEDDahua DH-CS4226-24ET-240-V2 24-Port PoE Cloud Managed Switch — 240W
Power and connect a multi-camera IP surveillance system with the DH-CS4226-24ET-240-V2. It provides 24 PoE camera ports and a shared 240W power budget, plus two Gigabit combo uplinks for the network or recorder. DoLynk Care and web management give installers visibility of the network and tools for maintenance.
Key Features
24 camera connections
Each PoE camera port runs at 10/100Mbps. Two Gigabit combo uplinks handle connections towards the wider network.
Shared 240W PoE budget
Ports 1–2 support up to 90W each; ports 3–24 support up to 30W each. All powered devices share the 240W total.
Managed maintenance
DoLynk Care, web management, port VLAN and LLDP help organise and manage compatible network installations.
PoE watchdog
Automatic monitoring can restart an unresponsive powered device. Long-range mode can extend suitable links, with reduced data speed.

Setup and Compatibility
Add up every camera’s maximum power consumption, including IR, warm lights, heaters and PTZ movement, and leave capacity for expansion. The 240W rating is a shared limit, not 240W per port. Each combo uplink is one logical connection: its copper port and SFP slot cannot be used as two independent uplinks. Long-range mode reduces the selected link to 10Mbps and is not a guarantee for every cable installation.
Choosing Accessories
Need a larger power budget? Compare the DH-CS4226-24ET-375-V2 375W switch. Add 8ware Cat6/Cat6A patch leads for the required connections. SFP modules and rack installation hardware should be selected for your network. The optional UPS must be sized for the switch and its full connected PoE load; a monitor connects to a recorder or computer, not directly to this switch.

Frequently Asked Questions
Are all 24 camera ports Gigabit?
No. The 24 PoE ports are 10/100Mbps. The two combo uplinks are Gigabit.
Can I power 24 cameras at 30W each?
No. The total PoE load must remain within 240W, even though individual ports have higher limits.
Does it record CCTV footage?
No. It connects and powers devices; recording requires a compatible NVR, server or camera storage.
