As if that was not trouble enough for them, they can now be filmed at work and obliged to attend a showing of their performance in court．

　　Selfridges was the first big London store to install closed-circuit videotape equipment to watch its sales floors．In October last year the store won its first court case for shoplifting using an evidence a videotape clearly showing a couple stealing dresses．It was an important test case

　　which encouraged other stores to install similar equipment．

　　When the balls, called sputniks, first make an appearance in shops, it was widely believed that their only function was to frighten shoplifters．Their somewhat ridiculous appearances, the curious holes and red lights going on and off, certainly make the theory believable．

　　It did not take long, however, for serious shoplifters to start showing suitable respect．Soon after the equipment was in operation at Selfridges, store detective Brian Chadwick was sitting in the control room watching a woman secretly putting bottles of perfume into her bag．

　　“As she turned to go,” Chadwick recalled, “she suddenly looked up at the ‘sputnik’ and stopped. She could not possibly have seen that the camera was trained on her because it is completely hidden, but she must have had a feeling that I was looking at her．”

　　“For a moment she paused, but then she returned to counter and started putting everything back．When she had finished, she opened her bag towards the camera to show it was empty and hurried out of the store．”
