Internet of Things - Smart Home Security System

The intelligent home security system realizes real-time monitoring and protection of the home environment through various sensors and networking equipment. With the help of Internet of Things technology, this system realizes the intelligent and remoteization of home security.

First of all, install door and window sensors on doors and windows. When doors and windows are opened abnormally, an alarm message will be sent to the user's mobile phone immediately. Secondly, the room is equipped with a high-definition camera, which can remotely view the situation at home in real time, and also has a mobile detection function. Once abnormal activity is detected, the alarm will be triggered immediately. In addition, smoke alarms and gas alarms can detect smoke and gas leaks in time and quickly notify users to take measures. Finally, the smart door lock is not only convenient for users to unlock, but also records the unlocking record. If there is any abnormal unlocking behavior, an alarm will also be issued.




















IOT

 Sensor

1. Door and window sensors: Magnetic sensors are generally used to determine the opening and closing state of doors and windows by detecting changes in magnetic fields.

2. Smoke alarm: Photoelectric smoke sensor or ion smoke sensor is mostly used. The former detects the scattering of light by smoke to alarm, while the latter works by detecting the impact of smoke on ions.

3. Gas alarm: Semiconductor gas sensor or catalytic combustion gas sensor is usually used. The former is sensitive to the change of conductivity of a specific gas, and the latter uses the heat generated by the combustion of combustible gas on the surface of the catalyst to detect.








Data transmission

Common methods include Wi-Fi, Bluetooth, Zigbee, etc. Wi-Fi transmission speed is fast and has a wide coverage range, but the power consumption is relatively high; Bluetooth power consumption is low, which is suitable for short-distance transmission; Zigbee has the characteristics of low power consumption, self-networking, etc., which is suitable for large-scale device connection.

Network protocol

The TCP/IP protocol will be used for the reliable transmission of data in the network, and the MQTT (Message Queuing Telemetry Transport) protocol, which is a lightweight message transmission protocol, especially suitable for Internet of Things devices. Limited resources and unstable network environment.

















Security System Brand - Hikvision

Hikvision is the world's leading provider of security and intelligent Internet of Things solutions. It was established in 2001 and is headquartered in Hangzhou, China.















Technology integration

1. Sensor and data analysis

• Hikvision uses various sensors in IoT, such as cameras, temperature sensors, humidity sensors, etc., to collect a large amount of data. Through advanced data analysis technology, these data are processed and mined, valuable information is extracted, and support security decision-making.

2. Edge computing and intelligent terminals

• Integrate edge computing power into security equipment to enable local data processing and analysis, reducing data transmission delay and dependence on the cloud. For example, the smart camera can detect and identify targets at the front end, and only upload key information to the cloud.

3. Application of communication technology

• Adopt a variety of IoT communication technologies, such as Wi-Fi, Bluetooth, Zigbee, etc., to realize the interconnection between security devices. At the same time, it also uses the high-speed and low-latency characteristics of 5G technology to improve the efficiency of remote monitoring and data transmission.
