Delhi residents are increasingly investing in advanced security technologies to protect their homes, moving beyond traditional locks to systems like infrared beams, face-recognition cameras, and electronic alarms. Many households now rely on smart devices that stream live footage to their phones, while others opt for budget-friendly options such as dummy cameras and simple alarms to create a sense of safety. Resident associations and security firms are introducing step-by-step installation processes, monthly maintenance, and emergency support, with some companies using international technology for rapid response.

The adoption of these systems has led to a significant rise in household security expenses, with costs far exceeding those of conventional locks. In neighborhoods with independent houses, residents are repurposing baby cameras and installing face-recognition CCTV for enhanced monitoring. Private control rooms and electronic entry systems are becoming common, and even house help are sometimes tasked with surveillance duties. As demand grows, a parallel market for affordable security solutions, including fake cameras and infrared alarms, is thriving, reflecting both the desire for safety and the financial pressures faced by families.
