How Does an ONVIF Encoder Work?
An ONVIF encoder works by taking analog video signals from sources like CCTV cameras and converting them into digital signals that can be transmitted over a network. The process involves several key steps:
- Signal Capture: The encoder receives analog video input from the camera, which could be in the form of composite video or other analog formats.
- Signal Processing: The encoder processes the analog video signal by encoding it into a digital format. This involves compression technologies such as H.264 or H.265, which help reduce the size of video files while maintaining quality.
- Network Transmission: Once the video is converted into a digital format, the ONVIF encoder transmits the video stream over the network to a compatible NVR or VMS. The encoded video can be streamed in real-time, providing immediate access to surveillance footage.
- Standardization: Since ONVIF is an open standard, any ONVIF-compliant device can communicate with the encoder, making it easier for users to manage their entire surveillance system without worrying about device compatibility.
