More customers are looking for a more affordable option when it comes to high definition security cameras or upgrading their existing system. Many of the professional systems that are currently available are very expensive, difficult to install and are usually only viable for bigger corporations. Some home and business owners are worrying about what to do with their already existing analog wiring from their old security camera systems. Luckily, there have been some newly emerging technologies like HD-TVI which is based on traditional coaxial cable for video and data transmission. This type of format allows for 720P / 1080P resolutions and offers consumers an economical solution to upgrade their existing surveillance systems.

HD-TVI advantages

Among current HD solutions, the distance of transmission, compatibility and cost are always problems for both manufacturers and users. Overall, HD-TVI technology can provide a more economical, easier to install and use solution for high definition analog surveillance system.

HD-TVI can convert digital signal to analog signal for expanding its transmission distance, lower total cost, reducing total video storage space. Through coaxial cable, the video transmission distance can reach up to 1500 feet without significant video quality loss. In addition, HD-TVI can transmit analog video signal with a resolution of 720P and 1080P at 30 frames per second. Simply by replacing existing analog cameras and DVRs with latest HD-TVI cameras and DVRs, users can upgrade their surveillance system to a brand new 1080P HD system. The best part is, that this upgrade doesn't require extra installation knowledge and is minimal in cost.

HD TVI really takes what’s great about having an analog system (great range and low storage space), and combines it with what’s great about a digital system (better picture quality and more features). The total cost is likely going to be less than other systems, once you factor in storage space. We’ve assembled a few pieces of HD-TVI technology that will enable you to easily upgrade your system whenever you’re ready for the switch:

Although HD-TVI technology is still fairly new for surveillance systems, resolution improvements and the ease of installation prepares many consumers to upgrade. More DVRs are starting to offer hybrid support, which enables homes and businesses with the option of slowly converting their old systems to newer technology. Scalability should be considered for new system installs, but it is difficult to argue the technological and financial benefit of being able to use your existing coaxial wiring. In summary, the low price difference is worth the safety of your home and business by providing the highest quality possible.
