Home Security Systems — Technology Overview

Restraints in Home Security Systems Market Growth

The high cost of installation and maintenance of home security systems is projected to be a major stumbling block to the market’s expansion. Customers are becoming more aware of the advantages of home security systems, but they are wary of making investments because security system prices are still out of reach for many consumers. The cost of installation is increased by expensive hardware and consultation on how to operate these systems. Furthermore, the total cost of ownership will be higher because it will include maintenance fees, monitoring subscription fees, part replacement expenses, and installation costs. Third-party monitoring players charge monthly membership fees ranging from $150 to $1500. Furthermore, the cost of installing home security systems varies depending on the level of customization required to include extra features and services such as two-way communication, smart video surveillance (with AI and other advanced image sensors), and cellular backup. Furthermore, the advanced analytics software installed in home security systems is costly, which adds to the overall cost of security gadgets.

Architecture of IoT

The Internet of Things (IoT) is a network of interconnected physical devices that can communicate and share data without requiring human involvement. Integrating electronic hardware such as sensors, software, and networking gear inside any object in the physical world that can be given an IP address to facilitate data transfer across a network can become a component of the IoT system. Because IoT allows us to collect information from all kinds of mediums, such as humans, animals, vehicles, and household appliances, it has been explicitly defined as an “Infrastructure of Information Society.”

  • Environmental Sensors: Light sensors, pressure sensors, and other sensors are incorporated in IoT devices to detect changes in ambient conditions in the device’s peripheral. Environmental sensors in IoT devices are primarily used to assist devices in making autonomous decisions in response to changes in the device’s periphery. Environment sensors, for example, are utilized in a variety of applications to improve the user experience (e.g., home automation systems, smart locks, smart lights, etc.).
  • Position Sensors: IoT device position sensors track the device’s physical position and location. Magnetic sensors and Global Positioning System (GPS) sensors are the most prevalent position sensors used in IoT devices. Magnetic sensors are commonly utilized as a digital compass to help with device display orientation. In IoT devices, on the other hand, GPS is employed for navigation.

Sensor-Based Threats to IoT Devices

Sensor-based threats are harmful behaviours that strive to achieve their destructive goals by abusing sensors, either passively or actively. Sensor-based attacks can be passive, such as watching the device’s activity without interfering with its usual operations, or active, such as injecting fake sensor data or uploading malicious sensor code to the device.

  • Location Inference: A new location-privacy attack based on acoustic side-channels was devised by the researchers. The assault is based on acoustic data embedded in foreground noise transmitted in a close context (e.g., a conference room). The researchers looked at how encrypted messaging clients in voice-call mode can be exploited to establish a location fingerprint using audio. The assault relies on a pattern of acoustic reflections of the human voice at the user’s location rather than any specific background sounds. The attack can be used to violate the location privacy of participants in an anonymous VoIP session, a Field-programmable gate array, or even confirm attacks that check if two audio recordings came from the same area regardless of the speakers.
  • Keystroke Inference: On IoT devices, keystroke inference is a common threat. The touchscreen, touchpad, and keyboard (external or built-in virtual or real) are used by the majority of IoT devices. When a user types or inputs data into a device, the device tilts and twists, causing data captured by sensors (e.g., accelerometer, gyroscope, microphone, light sensor, and so on) to deviate. In an IoT device, these discrepancies in sensor data can be utilized to infer keystrokes. Keystroke inference can be done on the device or on a nearby device utilizing an IoT device’s sensors.
  • Eavesdropping: Many IoT devices employ audio sensors to make calls, record audio messages, and respond to voice commands, among other things. Eavesdropping is a sort of attack in which a malicious programme secretly captures a conversation using audio sensors and extracts information from it. An attacker can either save the recorded chat to a device or listen to it live.

Opportunities and Possible Technology Enhancements in Home Security System

Conclusion

A smart home security system can improve your house’s security and provide you with peace of mind. However, by combining different smart systems, you can do a variety of functions remotely, including managing appliances and controlling lights, doors, and window coverings. Indeed, as technology advances and becomes more integrated into our daily lives, people are beginning to embrace a culture of convenience in which smart home technologies are connected, programmable, and controllable through a smartphone app.
