How many security systems are there? Simply put: What are their characteristics?

(1) Visual alarm system, which really exists, such as fire alarm system, smoke alarm system and earthquake alarm system. And security devices implemented by software and hardware and electronic devices.

(2) Virtual software mainly refers to the security alarm system of contemporary computer network system, which can be understood as a set of programs.

(3) Wireless alarm system.

Edit this wireless alarm system.

I. Internal wireless alarm requirements

Recently, campus crimes have occurred frequently, and kindergarten safety has become the focus of social attention. The system provides a solution for campus emergency alarm notification, which makes parents feel more at ease.

In case of emergency, press the preset wireless emergency call button, notify the security guard, office director and teacher of the special situation, and give an alarm. If there is an alarm interface of 1 10, you can also access the police station in time.

In case of emergency, start the internal security system scheme as soon as possible and notify relevant personnel for emergency treatment. Minimize the danger and continue to happen. And promptly notify the external community security, 1 10 and other quick support.

Second, the main components of the internal alarm system

1. Wireless alarm button (using FM technology to ensure stable and reliable transmission)

2. Wireless alarm receiving host (display alarm point number and continuously give out alarm sound)

Third, the placement position

Classroom, doorman, dormitory, canteen, activity area, community security, etc.

Fourth, how to use it.

In case of emergency, just press the alarm button, and all the places where the alarm host is installed can receive the alarm information and give an alarm sound. Relevant personnel should deal with it according to the operation plan made in advance. Security classrooms block doors and windows to prevent bad guys from entering; Security guards rushed to the alarm site to deal with it.

Systematic characteristics of verbs (abbreviation of verb)

Internal emergency notice to ensure that the danger is handled in the first time.

Wireless FM technology ensures stability and reliability.

Convenient and simple installation.

Encountered emergencies include: criminals, natural disasters, emergency medical care, etc.

Edit the perimeter induction alarm system in this section.

A, perimeter induction alarm system

Adopt the latest international perimeter security and perimeter alarm concept, "block first and then alarm". That is to keep the intruders out of the perimeter, stop them before the crime happens and let them retreat. When an intruder intrudes forcibly, the alarm system will give an alarm, notify the security personnel, and link the TV monitoring system. This is completely different from the traditional alarm and monitoring, because the traditional alarm and monitoring can only provide information and records when or after the incident, but can not effectively prevent outsiders from invading.

Second, the characteristics of the perimeter induction alarm system

1. A new concept of perimeter alarm combined with blockade.

2. Can adapt to all kinds of complex terrain, leaving no dead ends.

3. Powerful, damage-proof, approaching, disconnecting and crossing can trigger alarm.

4. Automatically store alarm information and print it independently.

5. There is no danger to life

6. Adopt advanced computer integrated system to overcome the shortcomings of poor security and high false alarm rate of traditional detectors.

Edit the burglar alarm system in this paragraph.

Anti-theft alarm system is a system that automatically detects the intrusion behavior in the security monitoring area by physical method or electronic technology, generates alarm signals, reminds the personnel on duty in the alarm area, and displays possible countermeasures. Anti-theft alarm system is an important facility to prevent accidents such as robbery and theft. In case of emergency, the location of the accident can be accurately displayed in the security control center through the acousto-optic alarm signal, so as to take emergency measures quickly. Anti-theft alarm system, access control system, closed-circuit television monitoring system, visitor intercom system and electronic patrol system together form a security system. The burglar alarm system usually consists of a detector (also called burglar alarm), a transmission channel and an alarm controller.

The alarm detector is composed of sensors and signal processing, which is used to detect the intrusion behavior of intruders. The device composed of electronic and mechanical parts is the key to the anti-theft alarm system, and the sensor is the core component of the alarm detector. Sensor devices with different principles can be used to form different kinds of alarm detection devices with different purposes.

(1) alarm detectors can be divided into infrared alarm detectors, microwave alarm detectors, passive infrared/microwave alarm detectors, glass breakage alarm detectors, vibration alarm detectors, ultrasonic alarm detectors, laser alarm detectors, magnetic switch alarm detectors, switch alarm detectors, video motion detection alarms, sound detectors and other types according to their working principles.

(2) Alarm detectors can be divided into active alarm detectors and passive alarm detectors according to their working modes.

(3) According to the different detection range, alarm detectors can be divided into point-controlled alarm detectors, wire-controlled alarm detectors, surface-controlled alarm detectors and space prevention alarm detectors.
