Although people’s awareness of placement is becoming stronger and stronger, and many families are installing video surveillance and burglar alarm products, we must face the fact that home security products such as home phone alarms are difficult to promote to most households. why? The original home phone alarms have some blind spots and dead ends, making it difficult for people to completely believe, as follows:
1, after the decoration of the house, gives people a feeling of comfort and beauty, make people feel comfortable living. If you decorate the doors and windows beautifully, a wall-mounted anti-theft transmitter will definitely affect the decorative effect of the entire house. At the same time, anti-theft transmitters mounted on doors and windows may be subject to human intervention or may be deterred from counter-alarm action.
2. Electronic products belonging to high-frequency emission are installed in the living room and the living room, and are easily interfered by the magnetic fields of large appliances, thus affecting the alarm effect.
3. Some wireless smart alarms use human pyroelectric infrared or microwave sensors. They can set dozens of defense zones and dozens of alarm calls. They have a high degree of intelligence and are networked with the community for system management. Although these products are highly intelligent, it is undeniable that their performance is flawed or even inadequate. Pyroelectric sensors may generate false alarms for the nearby high-heat, intense light and hot air currents. When the relative temperature of the environment is close to the human body temperature, missed reports may occur, and the glass and plates are less sensitive to the moving human body. At the end of the last century, the Northern Song Dynasty cultural relics of the Kaifeng Museum were stolen and occurred in the monitoring range of human pyroelectric infrared burglar alarms. Microwave detectors use the Doppler frequency shift feature to monitor moving objects in the defense area. When someone enters the defense area, they will immediately report an alarm, but animals in the defense area and shaking plants may cause false alarms. Microwaves have a penetrating effect on walls and floors. If they are not properly installed, neighbors' activities may also cause false alarms. As long as any false alarm or false negative is reported by any smart alarm device, it will affect the credibility of consumers and reduce the sense of security.
4. It is relatively safe to use a door sensor as a detector. No missed report or false alarm can occur because its alarm signal is generated after the doors and windows are pushed by the external force of the crime. No committing action will not generate an alarm trigger signal, but it has a large volume and is a surface-mounted device. It is vulnerable to hidden damage or the control of anti-alarm action. If acquaintances commit crimes, such things are more likely to happen.
5. The alarm device with double-detection function is now on the market, and the human pyroelectric infrared detection and microwave detection are in the same group of detectors. The use of microwaves is not blocked and the performance of smoke, light, and temperature change is insensitive. It supplements the inadequacy of human pyroelectric infrared detectors, and basically eliminates false alarms through the composite detection of both units. However, this may be missed because the human body's infrared radiation is easily shielded by walls, furniture, plates, and glass. Shuangjian detector can trigger an alarm only if both units detect the invading human body at the same time. If a rogue with anti-alarm experience is encountered, it enters the zone under the cover of the glass and the plate, then the double-sense detection is difficult to trigger the alarm only with the single-sense function. Under the effect of the anti-alarm, will it not be “with the police not reporting�
6, because the current video surveillance and security alarm electronic product detectors are almost all body-mounted equipment, in the installation process and form is not only unavoidable to the perpetrators provide damage to the target, but also to the thieves to create anti-alarm conditions . When the manufacturer researches and develops intelligent products without any false alarms, it may think that the detector is in the room. If the damage is not successful before the outdoor thief is successfully recorded or triggered, it ignores the diversification of the means of committing the crime.繺 - Open space-time, step-by-step committing crimes, using science and technology devices to commit crimes, perforating magnets to commit crimes, committing counter-alarms, using blind corners to commit crimes and so on. In order to eliminate the blind spot that has never been involved in the security and alarm industry, the home phone alarm detector can only be reduced in size, all concealed, and the perpetrators are not left with damage targets and anti-alarm conditions are created.
7. Smart alarms have difficult operation problems. Among low- and middle-income people, young people with thin hands may not use it. Some middle-aged and elderly people with anti-theft and anti-robbery awareness, and some even DVD remote control key functions and how to program are not clear, the smart anti-theft alarm code recording, programming, fortification, disarming and the occurrence of alarm after the rapid Dealing with, may only look "instrument" sigh!
The manufacturers of the security alarm industry should look to eliminate hidden dangers of home-telephone alarm detectors and enhance the credibility of people's security telephone alarms. R&D and production have stable physical properties and small volume. According to the characteristics of unattended home burglar alarms, they can conceal concealed detectors and triggers. The existing technical capabilities are not impossible but unexpected.
