Introduction to AHD cameras
AHD (Analog High Definition) cameras are a type of surveillance camera that uses analog signal transmission over coaxial cable, but with high-definition image quality. AHD cameras are becoming increasingly popular due to their ability to offer high-quality video at a lower cost than IP (Internet Protocol) cameras. AHD cameras also offer the advantage of being easy to install, as they are compatible with existing analog CCTV (Closed Circuit Television) systems.
- Analog signal transmission over coaxial cable
- High-definition image quality
- Lower cost than IP cameras
- Easy to install, compatible with existing analog CCTV systems
- Increasingly popular in the surveillance industry

How AHD cameras work
AHD cameras use a signal processing technology that converts analog signals to digital signals, which allows for high-definition video transmission. AHD cameras can transmit video signals up to 500 meters without the need for signal boosters or repeaters. The image quality of AHD cameras ranges from 720p to 1080p, and some models can even offer up to 5MP resolution. AHD bullet cameras are a popular type of AHD camera that is designed for outdoor use.

Advantages of AHD cameras
AHD cameras offer several advantages over other types of surveillance cameras. For one, they provide higher image quality than traditional analog cameras, with some models offering 1080p or 5MP resolution. This makes it easier to identify people and objects in the image. AHD cameras also have a longer transmission distance than traditional analog cameras, which means they can be used in larger surveillance systems. In addition, AHD cameras are relatively low cost, making them an attractive option for smaller businesses or residential use. They are also easy to install, as they can be integrated into existing analog CCTV systems without the need for additional cabling or networking infrastructure.

Main features of AHD cameras
AHD cameras typically offer a range of features that enhance their surveillance capabilities. AHD cameras are connected using coaxial cable, and the length of the cable can vary depending on the application. AHD cameras also have automatic exposure and white balance features, which help to ensure that the camera can adjust to changing lighting conditions, making the image clearer and more accurate. Infrared night vision allows the camera to capture clear images even in low-light or no-light conditions. Dynamic noise reduction helps to reduce noise in the image, producing a clearer picture. AHD cameras can also be connected to a DVR (Digital Video Recorder) for recording and playback of the footage.
