Surveillance and security are like having a friendly guard who watches over your toys so you can play without worries.
Surveillance is when someone or something watches to keep an eye on what's happening. Think of it like having a robot friend with eyes that never blink, it sees everything going on in the room.
Security is all about keeping things safe, like putting your favorite toy behind a door so only you can get to it. It’s like having a big, strong guard who stops anyone from taking your toys without asking.
How Surveillance Works
Imagine you have a camera that takes pictures of what's happening in the room, just like when you use your phone to take a photo of your drawing. These cameras send messages to someone else so they can see what’s going on, even if they’re not there. It’s like having a friend who can look through a window and tell you everything that happens.
How Security Works
Security systems are like a special kind of door or lock. When you press the right code, like a secret password, it lets you in. If someone tries to come in without knowing the code, the system will make a loud noise, just like when your toy alarm goes off if you forget to turn it off.
Together, surveillance and security work like a team: one watches what's happening, and the other keeps things safe!
