WiFi equipment can see your heart beating, but don't worry, it cannot possibly have any harmful effects on human physiology.

What? A camera can see you but cannot impact your physiology unless thrown at you.

A camera detects light. Light can certainly be dangerous to you.

How is that relevant? The camera isn’t blasting you with harmful light.
