Yes. Installing a hidden camera in the guest bedrooms of the respective individual's home to record intimate moments of their guests without their knowledge would be voyeurism as it involves the visual recording of another person for a sexual purpose or pleasure.  Irrespective of whether the hidden camera is able to capture any intimate moments of their guests, it would still amount to an act of voyeurism to install hidden cameras in the respective individual's home without their guest's consent nor knowledge since it will involve an act of non-consensual observation of the guests.
