PoE, or just “PoE,” refers to different standards or ad hoc systems that send both power and data over twisted-pair Ethernet cabling. It is a better way to send information than regular electrical wiring, which only sends power and needs separate wiring to send data. PoE sends both power and data over an Ethernet cable. It cuts down on the amount of wiring needed while keeping the integrity of the wiring.

Dahua Technology is a well-known global video-centric intelligent IoT solutions and services provider. Dahua Technology is constantly improving transmission technology and equipment in response to how customers use their products.

What is Power over Ethernet (PoE)?

Send its Power over Ethernet (PoE) 2.0 is made so surveillance data over Ethernet. PoE 2.0 has been added to the entire Dahua PoE switch series. It adds valuable features like PoE Watchdog, BT 90W (Red Port), Intelligent PoE, and Long Distance PoE Transmission.

Other intelligent features, like Green PoE and Perpetual PoE, were added in 2022. This collection of intelligent features makes Dahua switches much more helpful for surveillance and makes them easier to manage and keep up to date.

How Does PoE Camera Technology Work? 

Power over Ethernet, or PoE, is a technology for computer networks. It is used to power devices through cables connecting them to a computer network. Thanks to PoE technology, use two pairs of wires inside an Ethernet cable send both power and data from a single source.

PoE cameras send both electrical and data signals over a single Ethernet cable, so they don’t need separate plugs for power and data. It makes it easier and cheaper to set up security cameras and reduces the amount of wiring needed. IP (Internet Protocol) surveillance systems use more PoE cameras because they allow remote surveillance from anywhere with internet access.

To use PoE camera technology, users must buy an “injector” or “midspan” that plugs into a standard power outlet and connects to an Ethernet cable. Connect the switch that talks to the camera to the injector. It will get both power and data from the same Ethernet cable, which is connected to the switch that talks to the camera.

Taking Advantage of Enhanced Power Over Ethernet (PoE) technology

Dahua Technology has already discussed choosing the best device for transmission. Knowing the correct specifications, considering the needed features, using Enhanced Power Over Ethernet (PoE) to save money, and using wireless transmission in harsh environments can help you choose the right transmission equipment.

After figuring out which device is best for the situation, think about other ways to send the information based on the actual needs and requirements.

The Four Dahua Transmission Solutions

#1. IP CCTV Solution

Dahua’s IP CCTV Solution is a vital link between IP cameras and NVRs (network video recorders) in places like shopping malls and supermarkets.

In addition to its three main features (open, standard, and scalable), this solution has unified management, a PoE 2.0 power supply, and an industrial-grade switch. It gives the network a lot of room to grow and gives customers confidence in the quality of the products.

#2. Intelligent Transportation System

Traffic jams and ensuring people are safe on the roads are two problems that modern transportation has to deal with daily. The Intelligent Transportation System (ITS) monitors and sends real-time information about road conditions to solve this problem. It lets operators know what to do if something unexpected happens. Because of this, transportation is safer and runs more smoothly.

Dahua hardened/industrial switches

Because of their powerful hardware and software features, Dahua hardened/industrial switches are an excellent choice for the ITS solution. They can provide higher ESD and surge protection in challenging outdoor environments and at a wide range of operating temperatures.

#3. Intelligent Building Transmission Solution

As technology keeps getting better, video intercoms are being used more and more in intelligent buildings.

Dahua Video Intercom Systems

The Dahua Video Intercom Systems allow people in two or more places to talk to each other using voice and video. It makes transmissions more secure. Because they are built to industry standards, the Dahua transmission products in this solution are very reliable and work well.

#4. Elevator Solution

Elevator safety is essential to building owners because elevators are one of the most used building features.

Dahua Elevator Solution

The Dahua Elevator Solution allows monitoring of the elevator with video transmissions. Use the property management network for the data return link, or set up an outdoor wireless device. Use this solution from one place to another; it has a transmission range of up to 500 meters and is easy to set up.

Dahua PoE 2.0 Switches

PoE Watchdog (PD Alive) 

It checks the status of PDs (power devices) in real time, around the clock. If a PD stops working, the switch will automatically notice and restart the device. This feature saves users time and avoids manually restarting the IPC.

BT 90W (Red Port)

Their PoE switches meet the latest international standard, IEEE 802.3bt, and can send out 90W PoE. Their red port PoE now works with high-power PDs. (up to 90W).

Long Distance PoE 

The Dahua PoE switch series can send data up to 250 meters away, which is further than 100m. It is cheap to set up and can be changed to fit in many hard-to-reach places.

Intelligent PoE

A Dahua PoE switch tells each port apart by how important it is. If there needs to be more power to keep essential devices running smoothly, their switches will find the problem immediately. Also, “Green PoE” gives users a more environmentally friendly way to save money and reduce energy use by letting them turn on or off PoE for each port on a set schedule.

Conclusion

Buying Dahua security cameras with Power over Ethernet (PoE) technology is a great way to keep an eye on your home and your family. This technology gives you a reliable connection that works even if the power goes out. It is inexpensive and easy to set up. Many cameras have easy-to-use analytics like facial recognition and motion detection that add an extra layer of security. Lastly, every Dahua product comes with a two-year warranty so you can buy it confidently.
