Rising cost of feeling safe in Delhi: Face scans, AI cams, infrared beams

NEW DELHI: Once, a sturdy lock was considered enough to secure a city house. Today, homes are guarded by infrared beams, face-recognition cameras and electronic alarms. For some residents, it means spending thousands on smart systems that beam live footage of their homes to their phones. For others, it’s about cheaper fixes, like dummy cameras, that create an illusion of safety.

For Karol Bagh businessman Murli Mani, installing a smart alarm system was less a luxury, more a necessity.
