At present, safety issues have become a concern for families. Because the perpetrators of crimes are becoming increasingly professional and skilled, it is often reported in the news that some places have been robbed again, and the stolen items are all equipped with anti-theft devices. However, thieves still have the opportunity to take action. So how can we effectively ensure home safety? Only by constantly raising vigilance and relying on advanced home security alarm systems for prevention can home safety be ensured.

The so-called home safety mainly includes two different types of safety objects, first is the safety of personal and household property, and second is the safety of household equipment. When people talk about home safety, the former is the most talked about, while the latter has not received much attention. But it is precisely these overlooked parts that are often important links where danger occurs.

The perfect home security function is actually to connect home control devices to alarm facilities, realizing the functions of timely alarm, rescue and protection against illegal intrusion, theft, robbery and emergencies. From a functional perspective, it can also be divided into visual intercom, perimeter defense, home security, emergency assistance, wireless alarm, sound and light alarm, anti-hostage alarm, etc. Home security alarm systems include burglar alarms, fire alarms, gas leak alarms, and so on. All security detection devices in the home, such as fire detectors (smoke detectors, gas detectors, etc.) and anti-theft devices (various detectors, door contacts, anti-theft curtains, panic buttons, etc.), are connected to the home smart terminal to monitor their status. When an alarm occurs, the home intelligent terminal will perform various operations according to the settings, including starting the siren and linkage device, and dialing the set alarm phone number. If connected to the community security system, the alarm signal can also be sent to the community alarm monitoring center simultaneously.

1 Smart home access control

Access control should be considered the most important part of home security alarm systems. A good set of access control devices plays a very important role in protecting home security. In the process of constantly updating access control products, many manufacturers have gradually diversified the functions of access control. For example, many products now connect access control with community security system, using a control platform to control the security of the entire community. No matter which household has a situation, with just one button, the alarm signal can be transmitted to the community alarm monitoring center. Some alarm signals can also be directly transmitted to the public security department through the network. It Improves the speed of alarm and minimized the losses caused by family infringement.

With the continuous updating of science and technology, the current concept of home security has gradually shifted from the original simple individual protection to multimedia and Internet based protection. The system can automatically send an alarm no matter what the danger occurs. It greatly improves the safety factor of the home.

2 Closed circuit security monitoring system

As one of the monitoring methods for the security status of the work area, the closed-circuit security monitoring system, combined with the internal intercom system and public broadcasting system, can remotely respond and reduce the workload of management personnel, improve management quality and efficiency. As a powerful auxiliary mean of modern security methods, the closed-circuit security monitoring system transmits video images or alarm signals from various sites to the central alarm monitoring center. Duty management personnel can objectively conduct centralized monitoring of various areas without physically visiting the site, and make unified adjustments to guide evacuation and save a large number of patrol personnel. It can avoid many human factors and ensure the implementation of appropriate solutions in the shortest possible time.

3 Video intrusion alarm system

Video intrusion alarm systems generally consist of network cameras, monitoring hosts, and searchlights. The system adopts fuzzy control technology to effectively avoid the impact of small animals, debris, blizzards, etc. on the alarm, while ensuring immediate alarm for illegal climbing behavior of larger objects and people. When the network camera detects an intrusion signal, it will immediately sound an alarm to the community alarm monitoring center. The monitoring host of the alarm monitoring center will turn on the relevant area searchlight, emit an alarm siren, start recording, and the monitoring host will dynamically display the alarm area. The monitoring computer of the alarm monitoring center will then pop up an electronic map.

4 Home burglar alarm system

The home burglar alarm system consists of a security center management software, a home alarm control panel, sensors, and a network server. The main entry points are doors and windows, and sensors are armed in important locations and areas of the home to provide security and comfort for homeowners. Various types of sensors are introduced as follows: door contacts, gas detectors, smoke detectors, panic buttons, and other security systems are all used inside households. Infrared sensors, door contacts, smoke detectors, panic buttons, etc. are installed in each homeowner’s home. An alarm control panel is set up at the entrance of each unit, and a security center management software is set up in the alarm monitoring center. When a guest visits, pressing the outdoor button or the interviewee’s room number will trigger a ringing sound in the indoor area. At the same time, the display screen of the indoor unit will automatically turn on, showing the visitor’s image and outdoor situation. The host and guest can talk to each other and confirm their identity. After confirming their identity, they can use the unlock button on the indoor extension to remotely control the electric door lock for the guest to enter. Once the guest enters the door, the door will automatically close.

In addition, through community networking, centralized security alarm management can be achieved for all users who have installed home security alarm systems in the entire community. The home security alarm system of each household can transmit alarm signals to the alarm monitoring center through the bus, and the management personnel can confirm the location and type of the alarm. At the same time, the monitoring host also displays some information related to residents for security personnel to receive and handle the alarm in a timely and correct manner.

The technological innovation of burglar alarm systems in the security industry is relatively backward (compared to monitoring systems, access control systems, intercom systems, etc.). But in the past two years, the technology of burglar alarm systems has been gradually changing towards high-performance processors, large-sized LCD display keypads, and computer interconnection (based on TCP/IP transmission technology). Especially in terms of alarm zone setting, online programming, wireless alarm, etc., burglar alarm systems have made significant improvements, basically using mixed alarm zones and online programming and zone setting through computers. The phenomenon of relying on alarm keypads for online programming and zone setting input in the past is basically no longer present.

At present, the most critical aspect of burglar alarm systems is the innovation of various detectors, and the difficulty of updating the technology of detectors is relatively greater than that of alarm control panels. This requires a combination of interdisciplinary technological innovation, such as the improvement of optics, microwave, various sensors, and the development of special sensors.

5 Perimeter prevention system

The perimeter prevention system mainly monitors the situation around buildings to prevent illegal intrusion. It is the first line of defense for burglar alarm systems and also a very important line of defense. Perimeter prevention sensors can immediately detect intruders as soon as they enter the defense zone and issue alarms before they approach protected persons and property.

In summary, home security alarm systems are an important component of intelligent residential communities. They adopt real-time monitoring and layered defense for key areas in the community. In the future, the home security alarm systems will develop towards fully digital detectors, fully digital network platforms, and multi-angle control methods (i.e. home security alarm systems with multiple joint alarm technologies, research and development of multiple high-performance, low false alarm rate detectors), which will be greatly integrated with access control systems, communication systems, and monitoring systems. Ultimately, it will be a comprehensive security system integrated with computers, that is, all security subsystems will be integrated into the comprehensive security alarm system under the computer management platform. Let homeowners live in an invisible anti-theft net. It is both safe and user-friendly, providing comprehensive security for smart residential communities.
