Yes, hotels almost universally use CCTV security cameras, but their placement is strictly regulated by privacy laws. You will typically find cameras in public and high-traffic areas, such as lobbies, hallways, elevators, stairwells, and parking lots, to ensure guest safety and protect the property. In 2026, these systems are often integrated with AI for real-time security monitoring. However, it is strictly illegal for a hotel to have cameras in areas where guests have a "reasonable expectation of privacy." This means cameras are absolutely prohibited inside guest rooms, bathrooms, and locker rooms. Most major chains, like Hilton and Marriott, explicitly state in their privacy policies that they use signposted surveillance only in public areas. If you are concerned about "hidden" cameras, a simple "pro-tip" is to check for unusual objects facing the bed or to use your phone's camera in a dark room to look for the infrared light of a hidden lens, though such incidents are extremely rare in reputable, professionally managed hotels.
