Dahua DH-CS4220-16GT-135 16-Port Gigabit PoE Switch Price in Kenya

Dahua DH-CS4220-16GT-135 16-Port Gigabit PoE Switch Price in Kenya

The Dahua DH-CS4220-16GT-135 is a managed Gigabit PoE switch designed to connect and power compatible network equipment, including IP cameras, wireless access points and other PoE devices. It suits offices, shops, schools, hotels and CCTV installations that need centralized connectivity and power management.

Although commonly described as a 16-port PoE switch, it provides 20 network interfaces in total: 16 Gigabit PoE ports, two additional Gigabit Ethernet uplinks and two Gigabit SFP uplinks. The separate uplinks let you connect the switch to other network equipment without occupying a camera or access-point port. material.dahuasecurity.com

Its 135W shared PoE budget is the key planning limit. Select connected devices around their combined maximum power requirements, rather than assuming every port can deliver its individual maximum simultaneously.

Key Features and Benefits

Gigabit Connectivity for Cameras and Access Points

Gigabit interfaces provide capacity for traffic from multiple devices. They are useful where camera streams, wireless users and other applications share the same installation.

Actual performance still depends on the connected devices, cabling, uplinks and upstream network.

Centralized PoE Power

PoE carries power and data through one Ethernet cable, reducing the need for a separate electrical socket beside each compatible device.

The switch supports IEEE 802.3af/at equipment, with additional high-power support on designated ports. Verify each device’s required standard before connecting it.

Copper and Fibre Uplinks

The additional Ethernet uplinks suit nearby network connections. The SFP interfaces support suitable optical modules for fibre links.

Explore SFP modules when planning a fibre connection. Match the modules, fibre type and optical characteristics at both ends. These are Gigabit SFP interfaces, not 10Gbps uplinks.

Network and Power Management

Local management helps administrators inspect connections and control PoE operation. Cloud management through Dahua’s platform can provide remote visibility where configured and supported.

For an installation with several cameras, monitoring can help distinguish a power problem from a network connection problem.

These core values are documented in Dahua’s original and V2 datasheets. material.dahuasecurity.com

For physical planning, the original datasheet lists 440 × 220 × 44mm, while V2 lists 440 × 228.81 × 43.65mm. Confirm the supplied revision before allocating cabinet space. material.dahuasecurity.com

Understanding the 135W PoE Budget

The 135W figure is shared across all powered devices.

For example:

Example loadCombined requirementPlanning result10 devices at 10W each100WLeaves some budget for other loads16 devices at 10W each160WExceeds the available budgetOne device at 90W plus four at 10W130WLeaves little operating margin

These are illustrative calculations. Use each device’s maximum requirement, including infrared illumination, heaters or other features that increase consumption.

Allow margin for startup demand and cable losses. A switch with enough connection ports may still lack sufficient power for the proposed equipment.

Applications and Compatible Equipment

CCTV Networks

The switch can connect compatible IP cameras to a recording network. Recorder channel capacity remains a separate limit.

For example, the linked Dahua DHI-NVR1104HS-P-S3H four-channel NVR is a related recorder to assess for a small installation. Adding a larger switch does not increase its recording-channel allowance. Confirm camera compatibility and recorder bandwidth before purchase.

Wireless Access-Point Installations

Power compatible access points and connect their traffic to the main network. Check the PoE requirements of each access point, particularly higher-power models.

Browse access points and networking accessories for complementary equipment.

Office and Commercial Networks

Use the switch as a distribution point for wired equipment. Separate routing equipment should provide internet access, firewall protection and routing between network segments.

The MikroTik RB760iGS hEX S at MikroTik Kenya is an upstream router option to assess. Size the router around the workload and required configuration.

Management Features and Revision Differences

Both documented versions support network management, but the capabilities are not identical.

The V2 datasheet adds explicit IEEE 802.1Q VLAN support, static link aggregation, port isolation, mirroring and LLDP-based topology features. It also documents physical switches for operating-mode controls.

On V2, the physical PoE Watchdog and Extend controls operate only when Managed Mode is off, according to the datasheet. Follow the instructions for the supplied hardware rather than assuming the controls work identically across revisions. materialfile.dahuasecurity.com

How to Set Up the Dahua DH-CS4220-16GT-135

1. Identify the Hardware Revision

Check the label and supplied manual. Record the model, serial number and revision.

Use the corresponding documentation for management access, firmware and physical controls.

2. Calculate the Power Requirement

List each intended PoE device and its maximum power demand.

Keep the combined requirement below 135W with practical margin. Allocate high-power equipment only to suitable designated ports.

3. Install the Switch

Place it on a stable desktop surface or install it using the correct rack hardware.

Provide ventilation and connector clearance. Keep the switch indoors unless an appropriate protective enclosure is provided.

4. Connect Power

Use the supplied power cord and follow the unit’s rated supply requirements. V2 documentation specifies a built-in 100–240V AC supply. materialfile.dahuasecurity.com

A suitably sized UPS can help maintain operation, but its capacity must cover the switch and connected PoE load.

5. Connect One Uplink

Connect a Gigabit uplink to the router or main network.

Begin with one uplink. Do not add parallel connections until loop prevention or a supported aggregation configuration has been planned at both ends.

6. Access and Secure Management

Follow the supplied quick-start guide to locate and initialize the switch. Where it obtains an address through DHCP, check the router’s lease list or use the manufacturer’s discovery method.

Set strong credentials and record the management address. Avoid assuming a default address or password from another Dahua model.

7. Add Devices Gradually

Connect verified compatible PoE devices one at a time.

Check that each starts correctly and review its power demand. Use suitable Ethernet cable and inspect terminations if devices restart or fail to negotiate the expected link speed.

Browse Ethernet cables when preparing the installation.

8. Configure Network Separation Where Needed

Plan camera, office and management traffic before enabling VLAN settings.

Match access-port and uplink configuration to the router and other switches. Preserve a working management connection during changes.

9. Configure Watchdog Carefully

Where appropriate, enable PoE recovery for supported devices. Test its behaviour before relying on it.

Automatic power cycling can interrupt recording or other services, so it should address a specific operational need.

10. Use Extended Distance Only When Suitable

Dahua documents an extended mode of up to 250m at 10Mbps, with actual distance depending on cable and load conditions. This is not a 250m Gigabit connection. material.dahuasecurity.com

For demanding or longer links, assess fibre or another suitable design.

11. Test Under Realistic Load

Run the intended camera streams, access points and other applications together.

Check power usage, recording continuity, link errors and uplink traffic. Save configuration records and backups where supported.

Frequently Asked Questions

Can it power 16 cameras simultaneously?

Possibly, if their combined maximum demand fits the budget and each camera is compatible.

Does it record video?

No. A separate NVR or recording system is required.

Can it power 24V passive PoE radios?

Do not assume compatibility. Use a power arrangement expressly supported by the radio.

Does it provide Wi-Fi?

No. Connect suitable access points.

Does it replace a router?

No. It provides Layer 2 switching; gateway services require an appropriate router.
