With the improvement of the living standards of the residents in our country, in addition to the comfort and convenience in the requirements for residences, people are increasingly demanding for safety. Along with this, the huge "cake" in the consumer security market has gradually emerged, and civilian use of security is a huge point of interest growth. Because people's living environment is different, economic conditions are different, and family personnel are different, each family's configuration requirements for residential security systems are completely different. This requires the implementation of "personal customization" that varies from person to person in the residential security configuration. Program. 1, the use of single product security products Configuration: Smart Webcam Function: Wireless WIFI transmission, mobile phone remote monitoring, 270 degree panorama, motion detection alarm, audio and video monitoring intercom, video storage memory function, etc. Advantages: Cheap, simple and practical. Disadvantages: low safety performance, small monitoring range, prone to false alarms. 2, residential multiple security protection Configuration: smart network camera, wireless magnetic switch, wireless human body infrared detector, infrared curtain detector, infrared detector and so on. Function: Wireless WIFI transmission, mobile phone remote monitoring, 270 degree panorama, motion detection alarm, video storage memory function, detector linked audio and video surveillance intercom, prevent personnel door and window invasion, and prevent intruders from outside the house. Advantages: The price is cheaper, multiple surveillance detection protection, simple and practical. Disadvantages: The safety performance is not high, the monitoring range is limited, and false alarm may occur. 3, residential integrated security monitoring Configuration: smart network camera, wireless magnetic switch, wireless human body infrared detector, infrared curtain detector, infrared detector, intelligent control switch, intelligent control socket, wireless sound and light alarm. Function: Wireless WIFI transmission, mobile remote audio and video surveillance intercom, 270 degree panorama, motion detection alarm, video storage memory function, detector linkage monitoring, remote control of lighting fixtures, remote control of household appliances, hidden sound and light alarm, Prevent personnel and doors from invading and prevent intruders from outside the home. Advantages: Relatively inexpensive, multi-monitoring home appliances, audio and video care homes, security inside and outside the home, simple and practical. Disadvantages: The monitoring of home equipment is restricted, the scope of monitoring is not large, and there is a possibility of false alarm. 4, smart residential security Configuration: intelligent main control, smart camera, human infrared sensor, glass break sensor, vibration sensor, door sensor switch, etc. Function: The overall composition of security monitoring and protection system, can achieve mobile phone remote audio and video surveillance, residential all-round prevention of intrusions, real-time detection of doors and windows alarms, damage to housing facilities, alarms, prevention and control of regional human body into the police, can invade multi-level far-reaching defense Control outside the key areas, fully realize the multi-level telematics protection functions such as intrusion notification for outsiders, intrusion warning, intrusion alert, intrusion alarm, and alarm implementation. Advantages: Residential smart multi-level protection, multi-functional monitoring of doors and windows, personnel intrusion of infrared detection and real-time zone audio and video surveillance. High safety performance and stable equipment performance. Disadvantages: More investment, lack of security monitoring. 5, smart home "security" monitoring Configuration: intelligent main control, smart door lock, smart cat's eye, smart camera, hard disk recorder, human infrared sensor, glass break sensor, vibration sensor, door sensor switch sensor, water sensor, smoke sensor, gas (gas) intelligent control device, intelligent Window openers, smart switches, smart sockets, etc. Function: It constitutes an all-round security monitoring system, which can realize remote monitoring, full house intrusion prevention, real-time detection of doors and windows, alarms of damage to housing facilities, prevention and control of human intrusion alarms in the area, and discovery of local sound and light or language alarms in hidden areas. Far-reaching prevention and control Outside the key areas, the prevention and control functions of multi-layered telematics such as intrusion warnings, intrusion warnings, intrusion warnings, intrusion alarms, and implementation of alarms, etc., can be realized. At the same time, residential fire protection and gas (gas) can also be realized. Concentration exceeds the alarm limit and closes the gas supply valve, automatically shuts off the water supply valve when the flooding event occurs, and alarms, fires occur and the gas super concentration automatically opens or closes the window or exhaust fan, the omni-directional control of the security door, in addition to the anti-theft door fingerprint unlocking, sensing In addition to functions such as card unlocking, password unlocking, backup key unlocking, remote control unlocking, remote authorization unlocking, and linkage scene unlocking, all areas outside the security door can also be monitored in an all-round way, and intelligent situation models can be used to achieve security warnings. Important points for defense areas to achieve various ways Full control of the whole precaution. Advantages: Multi-level automatic control of residential intelligence, multi-functional monitoring of doors and windows, full control of natural disasters at home, key prevention and control of residential areas outside the security door, execution of scenario mode security prevention facilities, personnel intrusion of infrared detection functions and real-time zone audio and video monitoring functions, High safety performance and stable equipment performance. Disadvantages: too much investment. The above briefly describes the “personalized customization†points of residential security. With regard to the “personalization and customization†of the current family residential security system, the various types of smart home product configurations vary from person to person, cause to case, and item to case. It can be said that "the benevolent sees the benevolence, the wise sees the wisdom," and here only hopes to have the effect of "triggering the jade".
