Question
How does POE work in CCTV
Answer
PoE technology enables the transmission of power over Ethernet cables to network devices without the need for additional power lines. In this setup, switches or injectors act as Power Sourcing Equipment (PSE), delivering power to connected devices (PD), such as IP phones and cameras.
The transmission of power and data is separated to prevent interference and ensure safety. PoE standards are categorized based on power delivery capabilities.
Through PoE, users streamline the wiring process, increase flexibility, and eliminate the need for additional power outlets.
