An AHD camera (Analog High Definition camera) is a type of surveillance camera that transmits high-definition video over traditional analog coaxial cables (like RG59 or RG6). It is an upgraded version of standard analog CCTV cameras, offering better resolution and image quality while maintaining compatibility with existing analog infrastructure.
Key Features of AHD Cameras:
High Definition Resolution
Supports 1080p (Full HD) resolutions, which are much clearer than traditional analog cameras (like CVBS, which only supports 480p).
Uses Analog Cables
Works with coaxial cables (e.g., RG59, RG6) and BNC connectors, making it easy to upgrade older CCTV systems without rewiring.
Long-Distance Transmission
Can transmit video signals up to 500 meters (with a good-quality cable and signal booster) without significant quality loss.
No Compression & Real-Time Video
Unlike IP cameras, AHD cameras transmit uncompressed video with zero latency, making them ideal for real-time monitoring.
Compatibility with DVRs
Requires an AHD 1080p-compatible DVR (Digital Video Recorder) for recording and playback. Some hybrid DVRs support both AHD and traditional analog cameras.
Plug-and-Play Installation
Easy to install since it doesn't require network configuration (unlike IP cameras).
