Ever get the feeling you're being watched? 

A British TikTok user who describes himself as an 'ex-hacker' has shared his tips for spotting hidden cameras in hotel and Airbnb rooms.

Marcus Hutchins, who teaches cybersecurity and posts using the handle @malwaretech, recommends shining a torch around the room when you arrive to look for any potential recording devices.

In a video clip shared to the social media platform, Marcus said the first thing you want to look for devices that are conveniently placed where a 'creeper' would want to look.

'Take this fire alarm for instance, it is placed right above the bed,' he explained while guiding his own camera to the ceiling.

'Now one way to see if the device is a camera is to shine a bright light at it. If you hit a camera lens it's going to get a blue-ish reflection.

'Now you can test this by shining a light at your phone and seeing how the camera looks when placed under a flashlight.'

He then moves to a digital alarm clock beside the bed which also has a sneaky camera lurking behind the mirrored glass.

In the video, which has notched up more than 5.5million views, he explained how it's possible to see if a camera is there by shining a bright light on the glass.
