An AHD monitor refers to an Analog High Definition (AHD) monitor. AHD is a video transmission technology used for transmitting high-definition analog video signals over coaxial cables. AHD monitors are specifically designed to receive and display video signals from AHD cameras or AHD DVR (Digital Video Recorder) systems.
Here are some key points about AHD monitors:
1. Compatibility: AHD monitors are compatible with AHD cameras and AHD DVR systems. They are not compatible with other types of video signals, such as analog CCTV or digital IP (Internet Protocol) cameras.
2. High Definition: AHD technology allows for high-definition video transmission over analog infrastructure. AHD cameras capture video in high resolution, typically 720p or 1080p, and the AHD monitor can display the video in its native resolution.
3. Coaxial Cable Transmission: AHD video signals are transmitted over standard coaxial cables, which are widely used in traditional analog CCTV systems. This makes AHD a convenient option for upgrading existing analog systems to high-definition without the need for rewiring or replacing cables.
4. Plug and Play: AHD monitors are typically plug-and-play devices, meaning they can be easily connected to AHD cameras or AHD DVR systems using coaxial cables. Once connected, the monitor can receive the video signals and display them without the need for additional configuration.
5. Additional Features: AHD monitors may come with additional features such as multiple video inputs (to support multiple cameras), on-screen display (OSD) for adjusting settings and configurations, and various display options (e.g., split screen, picture-in-picture).
It's important to note that AHD technology is specific to analog video transmission and is gradually being replaced by digital IP camera systems, which offer higher resolutions and more advanced features. However, AHD monitors continue to be used in existing AHD systems or in situations where upgrading to IP-based systems is not feasible or cost-effective.
