EchoMaster HD-Over-Coaxial Cameras – Which One is Right For Your Application?
Are you thinking about upgrading your conventional analog surveillance system to high definition? But it seems difficult to decide which HD-over-coaxial technology to use.
AHD is a new HD CCTV standard developed by Korean chip manufacturer NextChip. AHD provides 720p max resolution output and long video transmission distances (up to 500 meters over traditional coaxial cable). AHD is also compatible with traditional analog equipment in limited configurations.
1. High Definition
High definition (HHD) is a video resolution that offers higher image quality and clarity than standard definition. It has a larger number of pixels and is used in TVs, monitors, digital cameras, and video game consoles.
The RHPC-HD10 C/CS is an ultra compact HD board camera offering 1280x720p resolution and a 1/3″ CMOS image sensor. It also includes an Analog Component ahd hd camera and RGB video output, On Screen Display, Slow Shutter, and Digital Zoom.
HD technology has become the standard for modern displays, cameras, and videos. It is much sharper and clearer than standard definition video, providing a more immersive and enjoyable experience for viewers. This is mainly due to its increased pixel count, which provides more detail and accuracy.
2. Long Range Transmission
Using a special cable, it can transmit power and video signal over a long distance without loss. It has a high transmission rate, which is up to 2.5 times higher than normal Ethernet cables. The pure copper cable can avoid the voltage drop and power loss problems caused by long distance transmission.
Eclipse’s AHD cameras use progressive scan CMOS image sensors that deliver up to a 1.0 megapixel, 1.3 megapixel, or 2 megapixel resolution; they are ideal for replacing older analog vehicle camera systems and can be used with existing coax cabling. These cameras have a wide field of view and are waterproof and fog resistant, ensuring they can be used in any environment.
AHD is a new HD CCTV technology that uses the same coax cable as traditional analog CCTV cameras for video transmission and a BNC connector to transfer power to the cameras. It can be used to upgrade any analog system to HD 720p video surveillance and is backward compatible with traditional analog cameras and recorders. Compared to HD-SDI and HD-TVI, AHD offers a lower max resolution of 720p, but is superior in video transmission over a longer distance (up to 500 meters) than other technologies.
3. Low Cost
Reversing cameras require less image and video detail than other security cameras. The 720p HD standard on EchoMaster’s AHD camera is more than enough for this application and still provides high-quality images and videos. Additionally, most of our backup cameras are waterproof and can withstand small water jets from sprayers or road debris.
AHD cameras work with existing coaxial cable and are far less expensive than network IP cameras. This makes them a great option for upgrading an existing analog CCTV system without having to replace the entire wired infrastructure.
However, it’s important to keep in mind that not all AHD cameras are created equal. Some use cheap components that are not able to deliver quality results. This can be evident by the quality of solder used in the camera’s circuit board. Low-quality solder will degrade quickly and may bubble in hot temperatures. Ensure you are buying an AHD camera that uses high-quality components to ensure reliability and longevity. This will minimize future maintenance costs.
4. Open Standard
Many users are confused when they decide to upgrade their existing analog video surveillance system with HD over coax cameras. Since there are multiple HD over coax camera standards (AHD, CVI, TVI), end-users can’t decide which one is the right choice for their application.
The answer to this question depends on your priority: if you prioritize analog video quality, cost-effectiveness, or ease of installation/upgrade, AHD might be the right solution for you. Likewise, if you want to monitor high-resolution footage on traditional CRT monitors, CVI or TVI is the right option for you.
Also, you need to consider the coax cable compatibility and power supply requirements of your system. Make sure the chosen technology can run on your existing coax cables (up to 320 Meters / 960 Feet at 720p with RG59) or use twisted pair cable with video baluns (maximum up to 150 meters without loss). Lastly, you must evaluate whether or not the selected camera supports GPS for driver monitoring, which is pivotal in curbing commercial vehicle drivers’ dangerous driving behaviors due to drowsiness and inattention.
5. Interoperability
Unlike IP cameras, many cutting-edge features like multi-exposure wide dynamic range (WDR) and edge storage are not yet available with HD analog systems. However, decreasing product prices and better industry support are driving HD analog adoption in some markets.
AHD (Analog High Definition) was developed to close the gap between existing analog systems and new HD technologies. It exceeds the transmission distance limitations of traditional 960H analog cameras, providing full-HD video over coaxial cable up to 500 meters. It ptz camera supplier also supports power and data over the same wires, allowing customers to use their existing wiring when upgrading to HD surveillance.
Designed with a proprietary closed technology system, AHD cameras are ideal for driver monitoring and commercial vehicle applications. They are typically used in truck and bus reversing cameras as they offer an optimal field of view and 720P resolution. They also feature a waterproof design and can withstand varying weather conditions. To display the live video of an AHD camera on a monitor, you can connect it directly to the DVR or use this AHD to HDMI converter.
