But Wait There’s More
Closed Circuit TVBy: Me…Again
What is it•It is a device that helps people with low vision see things that are too small
How Does it Work?• Its simple:
– Get in front of a closed circuit TV (CCTV)– Place the thing that you wish to view
under the camera– Look at the screen and then you will see
the thing you put under there in jumbo size.
– FOR EXAMPLE…
I would like to view this but I’m having trouble seeing what it is
• The CCTV can be hooked up to either a TV screen or it can be plugged into a computer monitor.
