Hidden cameras are illegal everywhere if they’re being used for immoral reasons. Installing a hidden camera is only legal if it's your own property and you have sound moral grounds to use secret surveillance. However, surveillance laws may differ between countries. If you’re traveling abroad, and you’re unsure how to spot a hidden camera, follow our simple guidelines. Use CyberGhost VPN to encrypt your devices when you connect to the Wi-Fi as well, since that’s another easy way people and cybercriminals can spy on you.
