According to the household excellent burglar alarm with scientific floating charge, eight measures are totally implemented, various excellent performances can be achieved after matching with existing patents and achievements, and the household excellent burglar alarm is a safety protector which is particularly suitable for households.

Description

technical field [0001] The invention belongs to the field of anti-theft equipment. Background technique [0002] Security accompanies safety, and safety accompanies happiness. As an anti-theft device with excellent performance, one of the most important points is that the security device can work normally when there is no electricity in the mains, so as to ensure the reliability of the security device. In order to meet this point, the battery is required to be matched with it, and scientific floating charging of the battery is required, because scientific floating charging can greatly improve the life of the battery and improve the reliability of the security device. As a special electrical appliance such as an alarm, it is very necessary. [0003] However, the current products do not do enough to this point. Many products only connect the charging power supply to the bridge input terminal, which only achieves the charging function, but does not achieve scientific floating...

Problems solved by technology

[0003] However, the current products do not do enough to this point. Many products only connect the charging power supply to the bridge input terminal, which only achieves the charging function, but does not achieve scientific floating charging. This is one of them. , The second and particularly important point is that although there are many alarm-type products, there are still deficiencies in the excellent alarm function and performance, and they need to be improved. There are two biggest weaknesses. The first is that they do not have effective The most important and basic function to keep non-insiders out of the door

The second is that the sensors used usually have such weaknesses that there is a possibility of false positives

[0004] Due to the above reasons, simple alarm products have not been popularized in thousands of households like anti-theft doors.
