DAHUA DH-HS4210-8GT-110 & DH-HS4208-4GT-90

Cloud Managed Gigabit PoE Switch with SFP Fiber | CCTV PoE Switch Promotion Singapore

The DAHUA DH-HS4210-8GT-110 and DH-HS4208-4GT-90 are hardened smart-managed Gigabit PoE switches designed for CCTV, IP cameras, PTZ, WiFi AP, video intercom, facial recognition, door access and other IP network devices.

The major advantages are Gigabit PoE, SFP fiber uplinks, up to 250m extended PoE transmission, Intelligent PoE, PoE Watchdog, VLAN, web management and centralized cloud management through Dahua DoLynk Care. (Dahua Technology)

Model Comparison

Dahua’s transmission catalogue confirms the HS-series positioning: the HS4210-8GT-110 has 8GE PoE + 2GE SFP and 110W, while the HS4208-4GT-90 has 4GE PoE + 2GE RJ45 + 2GE SFP and 90W. (Dahua Security Material File)

DH-HS4210-8GT-110 — 8-Port Gigabit PoE + 2 Fiber

This is the stronger choice when a site needs up to 8 PoE devices.

8 × 10/100/1000Mbps PoE

• 2 × 1Gbps SFP Fiber
• 110W PoE Budget

It supports IEEE 802.3af, 802.3at, Hi-PoE and IEEE 802.3bt. Ports 1 and 2 can support high-power devices up to the specified 90W port limit, while ports 3–8 support up to 30W each, subject to the 110W total switch budget. (Dahua Technology)

This makes it particularly useful for a combination such as:

Fixed IP Cameras + PTZ + WiFi AP + Video Intercom + Facial Recognition Terminal

DH-HS4208-4GT-90 — 4-Port PoE + 2 RJ45 + 2 Fiber

The smaller DH-HS4208-4GT-90 provides:

4 × Gigabit PoE

• 2 × Gigabit RJ45 Uplink
• 2 × Gigabit SFP Fiber
• 90W PoE Budget

Port 1 supports up to 90W while ports 2–4 support up to 30W each, again subject to the 90W total PoE budget. (Dahua Security)

This model is especially attractive for a smaller remote CCTV node where only 2–4 cameras are required but fiber connectivity back to the main building or control room is important.

Up to 250m Long-Distance PoE

Both models support Dahua’s long-distance PoE transmission up to 250 metres under specified conditions. (Dahua Security Material File)

Typical design:

IP Camera
↓ Cat5e/Cat6
DAHUA HS PoE Switch
↓ SFP Fiber
Main Network / Core Switch
↓
NVR / VMS

This can be useful for:

Factories • Warehouses • Car Parks • Construction Sites • Condominiums • Campuses • Guard Houses • Remote Buildings

There is an important engineering limitation: Dahua’s test data shows that extended-distance operation beyond 100m can reduce the Ethernet link to 10Mbps, and actual achievable distance depends on cable resistance, quality and the connected device’s power requirement. (Dahua Technology)

So 250m does not mean 250m Gigabit Ethernet.

PoE Watchdog — Useful for CCTV

One particularly useful CCTV feature is PoE Watchdog.

When correctly configured, the switch can detect an abnormal/unresponsive powered device and cycle its PoE power, helping recover compatible IP cameras without requiring a technician to physically disconnect and reconnect the camera.

This is valuable for remote installations such as:

Car Parks • Rooftops • Guard Houses • Warehouses • Remote Camera Poles

It can reduce unnecessary site visits for simple device lockups.

Intelligent PoE Management

The HS4210-8GT-110 supports PoE power-consumption management and individual PoE power control. (Dahua)

This provides better control than a basic unmanaged PoE switch.

For example:

Camera 1 → 7W
Camera 2 → 8W
Camera 3 → 9W
PTZ → 25W
WiFi AP → 15W

The network administrator can better understand and manage the available PoE capacity.

Fiber Optic CCTV Network

The SFP ports are a major advantage for multi-building CCTV.

SFP Fiber

↓
Core Network Switch
↓
NVR / Server

Fiber is particularly useful between buildings because it supports long-distance network transmission and provides electrical isolation between copper-network segments.

Actual fiber distance depends on the selected SFP transceivers and fiber type, not simply the switch itself.

Cloud Management with DoLynk Care

The DH-HS4210-8GT-110 officially supports centralized cloud management through Dahua DoLynk Care, in addition to local web management. (Dahua Technology)

This is a significant benefit for installers and maintenance providers managing multiple customer sites.

Instead of treating each switch as an isolated device:

Site A Switch
Site B Switch
Site C Switch
Site D Switch
↓

DoLynk Care

↓
Centralized Network Maintenance

Depending on the supported device functions and account configuration, this can simplify remote network visibility, configuration and troubleshooting.

VLAN for CCTV Network Segmentation

The HS4210 supports IEEE 802.1Q-based VLAN configuration, while the HS4208 family also provides managed VLAN capabilities. (Dahua Technology)

For example:

VLAN 10 → CCTV

VLAN 20 → WiFi

VLAN 30 → Door Access

VLAN 40 → Video Intercom

This allows one physical network infrastructure to support several IP systems while keeping traffic logically separated.

Recommended Applications

These switches are suitable for:

CCTV & IP Cameras • PTZ Cameras • WiFi Access Points • Video Intercom • Facial Recognition • Door Access • IP Phones • IP Speakers • Network Sensors • Fiber Backbone Networks

For a typical CCTV project:

DAHUA IP Cameras
↓ PoE
DH-HS4210-8GT-110
↓ Gigabit SFP Fiber
Core Switch
↓
DAHUA NVR
↓
HDD Storage / Monitor / Remote Viewing

For critical surveillance, protect the PoE switch + NVR + router/core equipment with an appropriately sized UPS. Keeping only the NVR on UPS will not maintain surveillance if the PoE switch and cameras lose power.
