How does CCTV help people with Low Vision?

The CCTV system is a highly adaptable and customizable technological device that can greatly enhance the quality of life for people with low vision. CCTV is an electronic magnification technology which projects images on a monitor, making it easier for people with low vision to read for extended periods of time. There is a range of different kinds of Video Magnifiers, but what they all have in common is that they contain a camera that magnifies and projects images onto a screen.

This device is made to be user-friendly for both those who are comfortable with technology and also for people who are less accustomed to using digital devices. If you find that your vision challenges are preventing you from living the life you want, you can speak to your low vision eye doctor about the CCTV which was created to help you and your personal vision needs.

Handheld CCTV Magnifiers

Handheld CCTV Magnifiers

Handheld magnifiers are great for those who need vision assistance while on the move, whether it’s for activities around the house like reading recipes, playing cards, or looking at a computer screen. These smaller magnifiers tend to be somewhat cheaper than large desktop models. However, being handheld devices, you need steady and available hands to hold them and they need to be charged.

Stand Video Magnifiers

Some Video Magnifiers come with stands and there are different kinds available. Some CCTVs come with four legs so that it can be placed on a book without having to be held. There are other magnifiers that have a handle, but they don’t always need to be held as they can be placed on a page in order to support itself. When the CCTV has a stand, the stand is already set to be at the perfect working distance from the text which means that when you use it, you don’t have to adjust it. A Stand Video Magnifier is ideal for a person who does not have the stability of holding an object in a steady fashion due to limited motor skills which could be a result of a wide range of conditions, including Parkinsons.

Desktop CCTV Magnifier

Desktop CCTV magnifiers have several advantages over portable magnifiers, for people who need them for reading and other tasks while at home. In addition to being hands-free and not requiring charging, they are more powerful and also larger. This means that they can also magnify more text at a time. They are also adjustable so that you can properly position the device over the text or other objects you need magnified.
