Description
Dahua CS4220-16GT-190 — a cloud-managed gigabit PoE switch that provides high-speed data transmission and power to connected devices over a single cabling infrastructure. The device supports the full range of PoE standards, including Hi-PoE and IEEE 802.3bt, making it a versatile solution for powering both standard IP cameras and high-load equipment. The gigabit ports ensure stable transmission of high-resolution video streams without loss.
Advantages
- Gigabit ports: a speed of 1 Gbit/s on each port ensures unimpeded transmission of high-resolution video and large volumes of data
- Hi-PoE and 802.3bt support: the ability to power PTZ cameras, high-power access points, and other demanding equipment
- PoE power management: intelligent power distribution between ports and overload protection
- Dahua cloud management: remote control and configuration without the need for physical presence at the site
- IEEE standards compliance: guaranteed compatibility with network equipment of any brand
- Reliable build: a quality component base and well-designed architecture for 24/7 operation
Applications
- Large video surveillance systems: transmitting high-resolution video streams from a large number of cameras
- PTZ cameras and pan-tilt devices: powering and controlling high-load cameras via Hi-PoE and 802.3bt
- Corporate Wi-Fi networks: powering gigabit access points in offices and public buildings
- Intelligent security systems: connecting video analytics cameras with high bandwidth requirements
- Industrial and warehouse sites: a reliable network for monitoring with minimal maintenance
Frequently asked questions
What is the advantage of gigabit ports over 100-megabit ones in video surveillance systems?
Gigabit ports provide a bandwidth reserve for high-resolution cameras and help avoid frame loss under peak load.
Does the switch support traffic prioritization?
The Dahua CS4220-16GT-190 managed switch supports QoS configuration and traffic prioritization through the cloud platform.
Can standard PoE devices, not just Hi-PoE, be connected to the switch?
Yes, the device supports all major standards — IEEE 802.3af, 802.3at, Hi-PoE, and 802.3bt — which ensures full compatibility with any PoE equipment.
