In a basement office-cum-showroom off Green Park in south Delhi, a demo is in progress. “Recording time is 12 hours, the images and sounds will be so clear you can see and hear everything,” offers the sales assistant. The customer, a man in his 40s with dark-circled eyes, is convinced; the deal is sealed. In an hour or so, the digital table clock he just bought should be sitting on his bedside table; hopefully, worth every penny of the 12,000-odd rupees he spent on it.
