 Home Security precautions include human precaution, physical precaution and technical precaution.

Human precautions include closing doors and windows, keeping house keys and door codes well, leaving valuables in a safe place before leaving your home, and personnel patrolling etc.
Physical precautions include strengthening doors and Windows, adding protective railings, fences, and locks.
Technical prevention means detection and early warning through the assistance of advanced science and technology such as sensor technology, electronic technology and computer technology. Technical security precautions include installation of anti-theft intrusion alarm system, video monitoring system and access control system.
The anti-theft invasion alarm system is equipped with three layers of defense on the outer wall, the doors and Windows of the outdoor courtyard corridor and the indoor space. Indoor and outdoor alarms are with different alarm technologies, such as active infrared alarm, passive infrared alarm, microwave alarm, dual technology alarm, cable alarm, laser alarm, etc.
The three basic elements of security prevention are detection, delay and response. Detection means to perceive the occurrence of explicit and implicit risk events and send out an alarm. Delay refers to the process of prolongs and postpones the occurrence of risk events. Response refers to the rapid action taken by the organization to prevent the occurrence of a risk event.

Three means of security prevention work on these three elements. The technical security system can give early warning in time, prevent effectively and dispose quickly. The digital security alarm system can accurately inform the alarm location and alarm type and send alarm information to the mobile phone and alarm center of the security personnel. The alarm system in conjunction with the smoke generator can make the scene of the crime shrouded in smoke, delaying the crime.
Taking home safety measures is the most effective way to prevent fire and burglary injuries. Intelligent and easy to operate technical safety protection equipment is a necessary appliance for home life. There are many kinds of family security alarm systems, some of them are combined with household appliances such as audio equipment, which are convenient to use. Home users can choose suitable security protection system according to their needs. At-home users can opt for a driveway alarm doorbell. Users who are not at home can choose to remotely monitor the APP alarm host.

A life-saving smoke alarm in a fire

 Why are so many people trapped in an indoor fire? According to statistics, more than 80 percent of those who died in the fire were smoke-choked. Fire combustion products contain a large number of toxic components, such as carbon monoxide, carbon dioxide, hydrogen cyanide, sulfur dioxide, nitrogen dioxide, etc., these gases have different degrees of harm to human body. One of the most toxic gases is carbon monoxide. Carbon dioxide is non-toxic, but when it reaches certain concentrations, it can stimulate a person’s respiratory center, resulting in shortness of breath, increased smoke inhalation, headaches, confusion and other symptoms. The vertical flow rate of flue gas is 3-5 meters per second, which is 8-10 times the horizontal flow rate.When the toxic smoke fills the entire evacuation channel, people may faint if they stay 1-2 minutes, and people may die if they stay 4-5 minutes.

Electrical and living fire carelessness is the two main causes of residential fire. The specific causes of electrical fire include line failure, electrical equipment failure, heating appliances used for a long time or too close to fuel, etc. The specific causes of careless use of fire in life are oil pan fire, baking, improper use of stoves, smoking, spontaneous combustion, playing with fire and so on. There are a lot of flammable objects in the room, some furniture, plastic combustion will produce a lot of smoke. The smoke would have lowered the line of sight so much that it was hard to see from a meter away. After the occurrence of an indoor fire, the escape time is limited. Under normal circumstances, the ordinary residence fire will deflagration in about three and a half minutes, and the chance of escaping after deflagration is very low.

The following measures can effectively reduce the occurrence of residential fires: timely replacement of aging and damaged electrical lines, replacement of old electrical appliances, regular inspection of gas lines, no smoking in bed, teaching children not to play with fire, keeping away from combustible materials when baking and heating, checking the use of electricity and gas before going to bed or going out, etc.
In addition, fire detection and alarm equipment should be installed in the home for early warning and early detection. Once there is a fire, the alarm device will trigger the alarm, even in the middle of the night people can evacuate and call fire police. Smoke alarms are the most commonly used fire alarm detectors. According to fire protection association, A smoke alarm should be installed in every bedroom, a smoke alarm should be installed outside the bedroom where the alarm can be heard through the door. At least one smoke alarm should be installed on each floor of the residence. The closer the alarm is to the fire, the faster it will work.Therefore, as many fire smoke alarms as possible should be installed in the residence.

There are many types of smoke detectors. Refer to another article at Fire safety cannot be ignored.
