AHD Security Cameras
AHD is an excellent choice for new installations or to upgrade older analog camera systems. It uses the same coax cable as traditional CCTV systems and it works at the same max distance.
AHD cameras also support audio-over-coax which is great for avoiding running an extra pair of wires. However, you will need a DVR that supports this feature such as our RK series DVR.
Image Quality
The image quality of a security camera is defined ahd security camera by how many pixels it can display, commonly measured in megapixels (MP). More pixels means higher resolution. A high resolution will allow a security camera to capture more detail and have greater zooming capability. However, the higher the resolution, the more bandwidth and storage will be required.
In analog CCTV cameras, the resolution is defined by the number of horizontal and vertical television lines (TVL). For example, a camera with 960H will have a maximum resolution of 960 x 480 pixels. AHD security cameras offer higher definition 720p than traditional analog CCTV cameras and can transmit a video, audio and control signal over one coaxial cable. This can help reduce wiring costs and maintenance.
EchoMaster offers a robust line of AHD security cameras, all with 720p standard HD and an impressive 180 degree field of view. These cameras are designed for a variety of vehicles, including cars, trucks, buses, vans, and more. All our AHD cameras have a waterproof design, with IP67 protection degree and a black glass front cover to help protect against sun exposure and IR reflection that can blind the camera.
CVI is a new technology introduced by Dahua in 2014 that uses composite video interface to provide high definition images at a lower cost than IP or analog. CVI is a patent-protected technology, meaning only Dahua can manufacture and use it. The latest version of this technology has a resolution of 4K (8MP) and supports Power Over Coax, which allows power, data and video to be run over the same wire as analog CCTV.
Low Cost
The ahd security cameras in this category are affordable for most homeowners or small businesses. These models are paired with AHD recorders to capture high definition video footage of the area you need to monitor. These digital video recorders, or DVRs, come in different sizes to accommodate your budget and storage needs. The camera resolution options in this section range from 2 megapixels, also known as HD-CVI or 1080P, to 8 megapixels. The higher resolution cameras are ideal for critical areas of your commercial vehicle or business that need to be monitored in extreme detail.
One advantage to AHD security cameras is that they are able to use existing coaxial cables. This is especially useful if you have several traditional analog cameras and are looking to upgrade to high-resolution models. AHD is able to transmit 720p HD video over standard coaxial cable, which reduces the overall cost of upgrading your system.
Another benefit of AHD is that it can be transmitted over longer distances than HD-SDI, which is limited to 333 feet. In addition, AHD can transmit video, audio and control (OSD or PTZ) over a single coaxial cable, which makes it easier to install a complete security system with less expensive auxiliary cabling.
Long Range
The long range of an ahd security camera is important because you want to be able to see intruders or other objects when they come into your view. The best ahd cameras feature a powerful optical zoom lens so you can zoom in on objects from afar. They also have an IR night vision mode that can illuminate up to 250 ft in the dark.
You can also use an ahd security camera to monitor your home or business remotely on your smartphone, tablet, or computer. Some models of ahd security cameras are even able to connect to your internet router so you can access your video picture from anywhere in the world on your mobile device.
One advantage of ahd security cameras is that they can work over existing coaxial cable infrastructure unlike IP cameras that require new ethernet cabling. Typically, ahd CCTV cameras will be able to transmit over RG59 and RG6 coaxial cables as well as standard CAT5e / CAT6 cable with the use of a video balun. This makes them a great choice for upgrading your existing analog system.
While there are many benefits to using an ahd security camera, it’s important to remember that this technology isn’t as advanced as IP CCTV. In addition, you should only choose a manufacturer that has a good reputation and can provide customer service when needed.
Open Standard
AHD security cameras have the ability to work with a variety of CCTV systems. They work well with analog CCTV cameras, and they are also compatible with IP surveillance systems. They use a standard coaxial cable for connecting the camera to the DVR, which is one of the most common ways that CCTV equipment is connected in the industry. This means that the AHD camera is an easy upgrade for your existing CCTV system.
AHD CCTV cameras can be used with traditional RG59 or RG6 coax cables for up to 320 meters (960 feet). They also support UTP cable ahd security camera using video baluns, which are available for those who want to use CAT5 wire instead of coax cable. The chip-set in an AHD security camera is open to all manufacturers, which allows for more choice in the market for end users.
Unlike many of the other HD surveillance camera technologies, AHD uses an analog transmission signal. Its main advantage is that it can run on the same coax cable as your existing analog system, making it a cost-effective way to upgrade to HD. It can also support up to 720p resolution, which is better than most conventional analog CCTV cameras. Another benefit is that it can provide a clear image in low light conditions. This is especially important for areas where there are multiple light sources that can cause distortion.
