Power over Ethernet (PoE) refers to any of the several standards or ad hoc systems that pass both electric power and data on twisted-pair Ethernet cabling. It’s a more efficient transmission method compared to ordinary electrical wiring, which only supplies power and requires separate wiring for data. Because PoE transfers both power and data over Ethernet cable, less wiring is necessary, while keeping the electrical wiring intact.
Dahua Technology has been developing transmission technology and devices based on customers’ application scenarios. Its Power over Ethernet (PoE) 2.0 is specially designed for surveillance transmission. In fact, the entire Dahua PoE switch series has been upgraded to PoE 2.0, which includes practical functionalities such as PoE Watchdog, BT 90W (Red Port), Intelligent PoE and Long Distance PoE Transmission. In 2022, other intelligent features were added such as Green PoE and Perpetual PoE. These intelligent functions significantly enhance the utility of Dahua’s switches in surveillance scenarios, making them more convenient to manage and maintain.
Here are four Dahua transmission solutions to consider, depending on the application scenario.
IP CCTV solution
Dahua’s IP CCTV solution serves as an important bridge that seamlessly connects IP cameras and NVRs in various scenario applications like shopping malls, supermarkets, etc. Aside from its three major characteristics (open, standard, scalable), this solution offers unified management, PoE 2.0 power supplies and industrial-grade switches, providing comprehensive network scalability and reliable product quality.
Intelligent Transportation System
Traffic congestion and road safety are a few of the challenges faced by modern transportation daily. To address this, the Intelligent Transportation System (ITS) was designed to achieve safer and more efficient transportation by monitoring and transmitting real-time road conditions, enabling operators to act accordingly in case of an unexpected incident.
In addition, the Dahua hardened/industrial switches can offer higher ESD and surge protection in harsh outdoor environments with a wide range of operating temperatures, making it an ideal choice for the ITS solution.
Intelligent building transmission solutions
With the continuous development of modern technology, video intercom is widely used in intelligent buildings. The Dahua Video Intercom Systems provide video and voice communications between two or more locations, providing optimised transmission security. With its industry-grade design, the Dahua transmission products in this solution offer reliability and cost-effective performance.
Elevator safety is of paramount importance for building owners as it is one of the most accessed amenities in the building. The Dahua Elevator Solution can effectively monitor video transmission inside the elevator. The return link of data can be achieved by using the current property management network or by installing an outdoor wireless device. This solution offers point-to-point application, up to 500-metre transmission distance, TDMA technology and easy installation.
