AHD stands for "Analog High Definition".
AHD is a video standard launched by NextChip, a similar standard has been developed by Hikvision: TVI or HD-TVI iscomparable to AHD. These two standards are ideal solutions for upgrading an analog video system to digital. Indeed with AHD or TVI, it is not necessary to modify the existing cabling of CVBS video systems (PAL cameras / NTSC cameras) if a higher resolution is required. Likewise, modern analog video recorders also offer AHD and / or TVI inputs. In addition to being able to stream video in HD or full HD resolution through an existing analog wiring (PAL / NTSC), AHD cameras also offer CVBS output: it is possible to use the digital zoom of the camera without lowering the resolution (CVBS) and thus reach zoom factors close to 30x, without loss with a full HD camera equipped with a 10x optical zoom.
The main advantages of AHD are:
- Low latency (similar to CVBS)
- Low bandwidth (about 30 times less than uncompressed Full HD)
- Full HD long distance transmission without amplification (> 500 meters)
- Flexible wiring (twisted pair, CAT wiring, coaxial wiring)

Board level cameras are particularly suitable for embedded monitoring or video control applications.
All models provide HD-SDI, EX-SDI and CVBS video Streams. Several sensors are avalable.
These cameras can support a lens holder and different lenses with fixed focal or motorized zoom lenses: please fill free to ask for your ideal configuration.
