To check a hotel mirror for a hidden camera, use the fingernail test: press your fingernail against the glass; a gap between your nail and its reflection means it's a normal mirror, while touching directly suggests a two-way mirror (potentially with a camera behind it). You can also use a phone's flashlight in a dark room to look for tiny reflections of light from a lens or use network scanner apps like Fing and Wireshark to find connected devices, as some cameras transmit over Wi-Fi, according to SafeHome.org and Norton.
