Eclipse AHD Cameras
Eclipse ahd cameras offer a cost-effective way to upgrade your existing analog video surveillance system to HD without changing the infrastructure. They can be used with traditional coaxial cable or ethernet cabling using video baluns.
Compared with TVI and CVI technologies, AHD offers exceptional image quality and long-distance transmission capabilities. This makes it an excellent choice for upgrading an existing CCTV system with a minimal impact on budget and time.
Image Quality
Unlike network IP cameras, AHD uses analog transmission technology to achieve HD video over coaxial cables. This allows customers to easily upgrade their existing analog CCTV system by simply replacing the camera and DVR. In addition, AHD has a maximum transmission distance of 500 meters over traditional 75-3 coaxial cables, allowing installers to run longer cable runs without using video baluns (or sacrificing image quality).
Compared with CVI cameras, AHD offers better image resolution and more detail. It also hd ahd camera features digital wide dynamic range enhancement to ensure high-quality images in challenging lighting conditions. The digital WDR function combines the brightest and darkest areas of the image to create a single highly detailed image. The camera also has an on-screen display (OSD) that allows users to configure the image settings such as brightness, gain, low light intensity and more.
Many end-users are confused with the different HD-over-coaxial technologies such as AHD, TVI and CVI. They are wondering which one is the best choice for their system. They all offer the same image quality – 1080p HD – but each of them has its own benefits and disadvantages.
AHD overcomes the most significant issues that held back other HD security technologies from gaining more market share. It is simple to install, works at the same max transmission distance as analog and requires no additional cabling like video baluns. It also does not require any changes to your wiring, a major advantage for businesses that already have extensive analog installations.
Resolution
Digital images are made up of rows and columns of pixels – the more pixels, the higher the resolution. This is important in CCTV because it affects how much detail an image can have, which could be the difference between identifying an intruder and just seeing their feet. Resolution also means the camera is able to record more footage in a given area because it has a wider field of view.
AHD cameras use traditional coaxial cable to deliver 720p or 1080p HD video signals, meaning you can upgrade your system without having to run new cables and install IP technology. The AHD format is an open standard developed by chip-set manufacturer Nextchip, and uses video baluns to provide a long distance HD solution that is backward compatible with existing analog equipment.
While AHD cameras are a good choice for upgrading to HD, they do not offer the same advantages as IP cameras. Compared to AHD cameras, IP cameras can capture 1.3 megapixels or more and have a wider field of view.
However, AHD cameras still provide a high quality ahd cameras image and video and are an excellent choice for backup cameras because of their superior reversing capabilities. These include a broader range of viewing angles, water resistance and a durable build. EchoMaster’s lineup of AHD backup cameras includes a variety of mount types for various vehicle applications.
Low Light Performance
Regardless of resolution, low light performance is the most important factor for a surveillance camera. It all boils down to the old “garbage in, garbage out” mantra that requires good sensor sensitivity and processing power to perform well.
Fortunately, there have been many improvements to cameras, both sensors and chipsets, that have significantly improved performance for low light conditions. Back-illuminated sensors are a good example, as they put the sensor’s sensitive surface on the opposite side of the chip wiring, which allows more light to reach each pixel. Newer processors also have much more sophisticated algorithms that help to reduce noise and improve image quality.
Another important consideration is how a camera performs in darkness. For this, it is necessary to test the camera in the environment where it will be installed or to find a location with similar lighting levels and patterns. It is also recommended to test a camera both in daytime and at night so that you get a better idea of how the camera will perform for specific deployments.
Some AHD cameras include a microphone with Audio-Over-Coax (AOC) technology that sends audio signals over the video cable, avoiding the need to run an extra pair of cables for audio. However, to use this feature you will need a DVR that supports it like our RK SERIES DVRs.
Motion Detection
The CMOS image sensor in this covert AHD camera captures high-definition video (720p) with great clarity. Its gimbal wall mount bracket makes it easy for installers to angle this indoor surveillance camera in any direction. With night vision capabilities, this camera is able to operate in both day and night environments.
Motion detection is an integral part of a home security system. When set up correctly, a motion detector will send notifications to you whenever it detects movement. The key is to optimize the sensor for your unique home environment. For example, you might want to limit the number of times your motion detection triggers by adjusting the sensitivity settings. That way, it will only alert you if something significant happens. Or, you may prefer a higher sensitivity setting that will respond to any change in the camera’s viewfinder.
If you have an older analog surveillance system on coax cable, upgrading to AHD is a simple solution that provides superior picture quality on monitors and a better HD recording on a DVR. You can even use your existing coax cabling and just replace the cameras and DVR with new Eclipse equipment.
If you are thinking of upgrading to an AHD system, it is important to understand how this technology differs from CVI and TVI. AHD is an open technology developed by NextChip, while CVI and TVI are closed technologies that are only compatible with their respective brands.
