Anti-theft alarm is an alarm instrument that uses modern scientific and technological means to prevent crime and detect criminal activities in a timely manner. There are many kinds of them, which can be divided into switch alarms, audible alarms, induction alarms, infrared alarms, laser alarms, etc. from the working principle. With the development of television technology and electronic computer technology, an advanced monitoring, control and alarm system for the joint use of television and computer has emerged. There are two transmission methods for the alarm signal: wireless and wired. With the strengthening of crime prevention work. Anti-theft alarms have played an obvious role.
Anti-theft alarm system is an important facility to prevent accidents such as qiang robbery and theft. In the event of an emergency, the location of the incident can be accurately displayed in the security control center through sound and light alarm signals, so that emergency measures can be taken quickly. The anti-theft alarm system, together with the entrance and exit control system, closed-circuit television monitoring system, visitor intercom system and electronic patrol system, etc., constitute a security precaution system. Anti-theft alarm system usually consists of three parts: detector (also called alarm), transmission channel and alarm controller.

The alarm detector is composed of sensors and signal processing. It is a device composed of electronic and mechanical components used to detect intruders' intrusion. It is the key to the anti-theft alarm system, and the sensor is the core element of the alarm detector. The sensor devices with different principles can constitute alarm detection devices of different types, different uses and different detection purposes.
How to buy anti-theft alarm
Home intelligent anti-theft alarms can be divided into two types: wired and wireless. Wired has the characteristics of stable communication, strong resistance to external sao disturbances, and low investment. It is very suitable for newly built buildings that have already reserved connection lines in the walls. But its shortcomings are mainly poor flexibility, which can not meet the changing needs of users, and it is a very troublesome thing for those already installed construction.
Wireless can avoid the above-mentioned similar situation, it has the characteristics of flexibility and simplicity, its shortcomings are mainly vulnerable to external interference and relatively high investment shortcomings.
We can choose wired or wireless home alarms as needed.
The home intelligent anti-theft alarm can also be purchased from the functions of on-site alarm and self-dialled alarm.
On-site alarm means that when a theft occurs, the probe transmits the detected signal to the host, and then the host sends out an audio alarm sound, which has a certain deterrent effect on the thief. The automatic dian dialing alarm not only has the function of on-site alarm, but also automatically dials the number we have set, and can also give a detailed explanation of the specific location of the alarm. With this function, we can form an alarm local area network center with the community security and alarm center. When we choose, we consider the on-site processing part and subsequent processing part according to our family size, family construction method, surrounding specific conditions and family members and other factors.
With the continuous development of semiconductor electronic components, at present, people's home intelligent anti-theft alarms have greatly improved in terms of process and product quality. At the same time, prices have also fallen sharply. Now the price is about 1,000 yuan. This brings great convenience to the use of home anti-theft alarms for ordinary families.
