Valerie (full name withheld) posted these photos of spy cams found in her hotel room in a "famous resort" in Malacca, Malaysia. According to her FB, the villa's management denied all responsibility for these cams, so she shared the photos to warn others. Her friend was the one who spotted the cams. The friend got suspicious because she had seen these cams for sale online before.
A quick check on eBay confirms how easy it is to buy these cameras that look like clothing hooks, with a lens where the screw should be, and an microSD card inside for recording.
Valerie warns, "大家在外面也要小心，看到类似的挂钩多加留意."
They did try to see if there was any footage on the cards but couldn't read the data. Valerie writes, "我们有尝试用手机read memory card，但是read不到，拔出来看时发现后面的晶片，其中一个已经走形了，不清楚是原本就这样，亦或是我们插进去手机时弄到的，不过不管怎样memory card是确定坏了和read不到的."
May have been a video format issue. In any case, do check your rooms when you check in. You never know what nefarious schemes are afoot.
