In the video – which has amassed more than 26 million views at the time of writing – Amy films herself entering a hotel room and immediately locking the door behind her. To add an extra layer of security, she then places a portable door lock at the base of the door. Unlike exterior locks, portable locks can only be used inside a room and come in a variety of forms to protect against unwanted intrusions.
As an additional precaution, Amy then places a mug over the door handle. This measure ensures the occupant is alerted to any attempts to enter the room, even if they are sleeping or in the shower – if someone tries to open the door or jiggle the handle, the mug will fall. The noise may also deter the possible intruder.
The video then shows Amy drawing the curtains and switching off the lights before using an infrared detector to scan the room, its appliances and furnishings – including the vents, shower head and plugs. The device can be used to detect any cameras that may have been stealthily hidden in the space. Some hidden cameras emit IR (infrared radiation) light, which isn’t visible to the naked eye. Most Internet Protocol (IP) cameras – digital video cameras – also use infrared for night vision.
Amy is then seen checking the bathroom mirror to ensure it’s not made of two-way glass. A two-way mirror is made with glass that is reflective on one side and clear on the other, giving the appearance of a regular mirror to those who see the reflection. However, anyone on the clear side can use the mirror like a window – able to see everything on the other side of the glass.
A simple trick to check whether a mirror could be two-way is to place your fingertip on the glass. As demonstrated by Amy, a standard mirror will show a small gap between the finger and its reflection – indicating the glass is innocuous. However, if a mirror is two-way, the finger will appear as though it is directly touching the reflection, with no gap between them.
Other clips in the video show Amy placing a paper cover on the toilet seat, disinfecting the inside of the room’s kettle and sanitising her coat and shoes.
