There are cameras everywhere, from your phone, to your laptop to the baby monitor. And they're connected to your Wi-Fi so that means they can be hacked, or taken over by someone else.
There are things you can do to protect yourself against criminals hacking into your camera.
First, many webcams have a factory default password. Check your laptop and go in and change that password.
Take security seriously by investing in security software that includes a firewall.
Take a look at your router, this is the front door for your devices at your house.
Is it new? Are there updates for it? Ignoring your router is ignoring your security.
Those were some high tech ideas now let's go low tech.
Put a post it note or piece of tape over your camera. Facebook's Mark Zuckerberg does it, you should too.
Unplug and power down. Don't leave your devices with cameras running in the background.
And finally, it's okay to be paranoid. If you don't want your camera to photograph you doing something sensitive - don't do something sensitive in front of it.
