AHD Camera Technology Explained
If you decide to upgrade your conventional analog surveillance system to High Definition, you may be confused about which HD-over-coaxial technology to choose. There are 3 different technologies – CVI, TVI and AHD.
AHD is a new analog video transmission, recording and displaying technology. It uses an open standard chip-set from a third party manufacturer – Nextchip.
AHD Technology
AHD cameras are an excellent option for those looking to upgrade their existing analog CCTV system. They offer superior image quality compared to traditional analog CCTV systems and ahd camera can be installed using existing coaxial cables. In addition, some models feature built-in microphones with Audio-Over-Coax (AOC) technology, allowing you to transfer audio over video without the need for additional cabling.
Developed by Nextchip, AHD technology allows for up to 720p resolution over traditional coaxial cable at distances of up to 500 meters. The technology also includes a variety of advanced features, including digital noise reduction and image stabilization. It also offers an easy plug-and-play installation process, making it an ideal solution for both professional installers and DIY users.
AHD technology is also compatible with a range of DVRs, making it an excellent choice for those looking to upgrade their existing analog CCTV systems. Unlike CVI and TVI cameras, AHD supports progressive scan CMOS image sensors for improved picture quality. This means that AHD can achieve higher-resolution videos and better night vision performance compared to analog CCTV systems. In addition, many AHD cameras come with infrared LEDs to improve illumination in low-light conditions. Moreover, they support the transmission of a live feed to mobile devices for remote monitoring. This makes them an excellent choice for fleet management applications, enabling companies to keep track of their vehicles’ locations and driver activity.
AHD Resolution
If you are looking for a cheap and affordable way to upgrade your standard definition CCTV system, an AHD camera is a great option. These cameras are able to transmit HD video over traditional coaxial cable and can be used with existing DVRs. They also offer excellent low light performance and come with a variety of features that make them a good choice for a wide range of applications.
When choosing an AHD camera, you should consider your surveillance needs and how much resolution is necessary for your application. For example, if you want to see the license plate of a suspicious vehicle, you may need a 5MP or higher AHD camera. However, if you just want to keep an eye on your kids playing in the backyard, a 960H analog or 720p AHD camera may be sufficient.
AHD cameras are also a great choice for use in high-traffic areas, as they can be easily installed on walls or ceilings. Additionally, they can be connected to a network via IP protocol and accessed from anywhere in the world with a smartphone or tablet. This makes them an ideal solution for businesses and government agencies that require 24/7 monitoring.
AHD cameras can be used with a variety of DVR systems, including CVI, TVI, and 960H. In fact, you can even use AHD cameras with existing analog DVRs if you upgrade your DVR to an AHD-compatible model.
AHD Transmission Distance
AHD is an analog high definition closed-circuit television video surveillance standard that uses traditional coax cable (RG59 or RG6) to transmit HD 720p or 1080p video from security cameras to DVRs. Using this technology installers can upgrade their analog CCTV systems to high definition without replacing all existing cables.
Unlike HD-CVI and HD-TVI, AHD doesn’t degrade over long cable distances. This makes it a good choice for surveillance applications in which image clarity is paramount.
However, in order to reach these long distances the coax cable quality must be top notch. We recommend installing a quality cable with an RG59 or RG6 rating of no less than 5C-2V. This will allow for maximum cable lengths of 500 meters LOS.
We also offer amplifiers that can be installed on either the camera or DVR end of a cable run to boost the signal and increase the max cable distance. The AMP-101HD is one such product. A single AMP-101HD can boost the signal of an AHD, HD-CVI or HD-TVI camera up to 1500 meters / 5000 feet and for HD-SDI cameras up to 1200 meters / 4000 feet.
Alternatively, if you don’t want to run cables at all we can offer a wireless AHD transmitter and receiver with a radio transmission range of up to 500 meters. The system works on the 5.8GHz ISM Smart WiFi Camera band and does not require a license to operate. It can be used to connect work cameras to a monitor in elevator shafts or other locations where pulling wires is impossible.
AHD Compatibility
AHD is a closed-circuit television video surveillance technology that uses coax cable to transmit HD video from security cameras to DVRs. It is an alternative to traditional analog CCTV systems and can be used with existing wiring. It can deliver a higher resolution than HD-SDI and is better than traditional analog CCTV systems. However, it cannot transmit the same distance as HD-TVI or IP cameras.
Most AHD cameras are equipped with a CMOS image sensor and offer high resolution at 720p. They also provide advanced features such as WIDE DYNAMIC RANGE and BIT DEPTH REDUCTION. These functions are useful in areas with a wide range of brightness levels. They can also capture an image in low light conditions.
These features make AHD cameras a great option for fleet management applications. They can record footage in a 360-degree view, making it easier to locate vehicles and other items. They can also reduce downtime by allowing drivers to see what is going on around them in real-time.
If you are looking to upgrade your analog CCTV system, the Eclipse line of AHD cameras is a good choice. These cameras can be used with existing analog BNC wiring at a higher resolution than traditional analog CCTV. They can also use standard RG59 coax cabling for up to 500 meters or CAT5 network cables with video baluns.
