What is the AHD CCTV System?
The ahd cctv system is the latest HD CCTV technology that uses traditional coaxial cable infrastructure to transmit high definition video from cameras to DVRs. This allows you to upgrade your old analog system without replacing the entire infrastructure.
AHD cameras offer better clarity than analog 960H cameras and the image quality is very comparable to a full network HD 1080p camera.
AHD Cameras
AHD (Analog High Definition) is a new solution that bridges the gap between existing analog systems and high-end HD systems. This solution utilizes the same coaxial cables that were used with traditional analog CCTV systems and allows for full HD 1080p video to be transmitted over those cables at distances of up to 500 meters.
A HD AHD camera is just like a traditional analog CCTV camera with the exception that it has an image sensor with a higher resolution and a wider field of view. This allows for a much more clearer and detailed image and is great for monitoring larger areas. AHD cameras also ahd cctv system feature a digital zoom function that allows you to digitally zoom in on the subject without losing quality.
This allows you to see a lot more detail and clearly identify faces, license plates etc. AHD cameras are very easy to install as they are back compatible with traditional analog systems and use the same BNC cabling that is used for analog cameras. The only difference is the AHD cameras will need a special AV converter or DVR that can convert the analog signal into an digital HD signal.

AHD DVR
A HD CCTV DVR records video files that are saved to an internal hard disk and can be played back locally or remotely on a computer or mobile phone. These AHD DVRs work with standard RG59 coaxial cable and typically come without the hard disk to let you choose a suitable size based on your storage capacity needs, although special Videosurveillance hard disks for long durability are available in our catalogue.
These DVRs also feature RCA audio inputs for connecting microphones for analog cameras (AOC) or to connect external devices like alarm sounders to trigger alarm actions. They also have RS485 inputs to connect switches or detectors which can be used for motorized cameras.
Most of these AHD DVRs support cameras with traditional analog NTSC or PAL technology as well as AHD, HD TVI and even sometimes IP Cameras. This makes it easy to upgrade an existing CCTV system to HD video surveillance and still keep the same physical infrastructure that already exists for power, control and monitoring.
An important aspect of an ahd DVR is the resolution, which refers to how much detail can be seen on a screen when the video is viewed. The higher the resolution, the clearer the image will be and it is therefore important to consider what resolution you need for your project.
