External vision system

Have you ever sat in a car and noticed a camera on the back? That's kind of like an external vision system! It's a special camera or sensors that help us see things that are outside of our own eyesight.

Just like how our eyes see things around us, an external vision system helps us see things in different directions or far away from where we are. For example, a car's external vision system can help the driver see what is behind them when they are backing up.

Some external vision systems can even help robots or self-driving cars see the world around them. This can be really helpful to keep them safe and help them move in the right direction.

Overall, an external vision system is like having extra eyes that can help us see things we wouldn't normally be able to with our own eyes.
