Most Affordable price of HD Analog Camera in China

In the digital video security industry, the subject of high-definition (HD) digital cameras can sometimes spark some argument. Many security companies vigorously promote the advantages of IP cameras as well, and for good reason: they offer more security and better image quality, and their adoption rates are much higher than analog ones. And yet, HD cameras are not all that affordable, which makes the debate about them heated up. What's the difference between HD cameras and analog ones?

The first and most important difference is in the source. With an IP camera, the source is always from the internet; with an analog device, you're either using a wired connection or a fiber-optic connection to transfer the signal. With both types, though, there is an option to use a USB connection instead of a wired connection, which simplifies the installation process and cuts down on potential signal interference. Digital cameras also usually come with a monitor, which can make it easier to display what's going on with the camera at that particular moment.

But there are a few differences between analog and HD analog camera in the manner in which they capture and transmit the signals. For instance, while there are certain IP networks that allow for the transmission of two-IP signals, such as HDCP or High Definition Digital Copy Protection, many IP networks prohibit the use of HDCP. Analog cameras, on the other hand, can capture and transmit through different types of physical media including RCA, DVI, VGA, USB, LCD, and plasma screens.

This means that there is no incompatibility between analog infrastructure and various types of IP networks. There's also no possible distortion when transferred via different technologies, as there's very little loss of color or other characteristics of the original image. And thanks to improvements in picture quality in recent years, it has become much easier to use IP networks to transfer signals between devices.

HD analog cameras, on the other hand, are much smaller and more fragile than their larger cousins. This means that there is a higher risk of damage to the device in the event of a power surge. It also means that HD analog equipment is generally only compatible with certain devices and video networks, like those provided by cable and satellite companies. Connecting HD analog camera to a home network, or even a Wi-Fi network, could prove problematic, because their signal can easily be decoded by wireless network routers and access points. Some users have found an easy way to bypass the problems by setting up a wireless IP cabling between their analog camera and their television.

For people who are interested in getting a digital camera but aren't quite ready to commit to an extended commitment, an analog camera may be the right choice. These devices offer great picture quality and portability, and they are much easier to use than their newer counterparts. If you're eager to explore the world of digital photography but aren't quite sure if you should buy one, an analog camera may be just what you need.
