7 good reasons to switch to AHD technology for your video surveillance
Gigamedia cameras and video recorders now incorporate AHD technology.
This technology means that video signals, colour and brightness are handled and processed separately, which produces sharper images with more reliable colours.
The combination of a new generation of CMOS sensors and new image signal processors (ISP) produces high quality videos with up to 2 million pixels.
The range includes everything you need (dome cameras, tube cameras, speed dome cameras, hidden cameras, etc.)
AHD technology is:
1. Hybrid and backward compatible : AHD video recorders are able to process images from standard CCTV cameras.
2-High quality : High resolution images up to 1080 pixels
AHD technology produces images with up to 1080 pixel resolution. Standard CCTV resolutions initially in D1 format (720X576) progress to full HD format (1920x1080). 720 pixel (1280x720) and 1080 pixel (1920x1080) standards are now accessible standards with analog technology.

The same image but with CCTV technology.
3- Straightforward : Easy to install (plug and play).
4- Fluid : No latency between the event and viewing the event.
5- High-performance : Signal transmitted over 500 m (Coaxial) or 300 m (CAT5e twisted pair + baluns).
6- Scalable : It is possible to use the existing CCTV infrastructure. AHD technology is compatible with pre-existing KX6 coaxial cabling, thereby safeguarding previous investment.
7- Accessible : Excellent quality/price/performance ratio.
