Brief introduction of anti-theft alarm system

1. The alarm system is a system that uses an infrared device and an alarm host to control illegal intrusion. According to different needs, there are different configuration methods.

1. Perimeter alarm system

There are many alarm detectors with a long perimeter. Generally, a bus-type alarm system is used. The alarm detector uses an active radio detector. The entire system consists of a detector, an alarm signal conversion module, an alarm bus, an alarm switchboard, and an alarm horn. Its powerful and stable performance. The perimeter distance is not limited, the host can receive the alarm detector signal from a long distance through the branch amplifier. The control keyboard and alarm horn can be installed in the main control room or any part of the bus. When the perimeter is very long, more than one duty room is required. This system is very suitable.

2. Alarm system in the building

The alarm system in the building can be combined with the outdoor alarm system to form a large system, or an alarm system can be formed separately according to the needs. According to the number of indoor alarm control points, you can choose a bus-type alarm host, or you can choose a general form of alarm host.

3. Small alarm system or home alarm system

There are only a few alarm detectors in the small alarm system or the family alarm system. Generally, there is no alarm control. The duty room is mostly managed by the guard, or the alarm is given to the designated person in charge by telephone.

2. Intelligent security includes security alarm system, access control system, parking lot management system, security patrol record system, attendance system, intercom doorbell, etc.

1. Security alarm system

It consists of a probe and a host. When the probe detects the intrusion alarm information, it sends a signal to the host. After receiving the signal, the host sends an audio signal or dials the phone to dial the alarm, or controls the camera to take a live image. If it is a fire signal, The automatic fire extinguishing device can also be activated to extinguish the fire. According to the user's alarm needs, the alarm probes can be installed in different locations. There are glass breakage induction probes to prevent window breakage, intrusion alarm probes to prevent intrusion from a certain channel, smoke probes and temperature rise probes for fire prevention . There are gas probes to prevent harmful gases.

2. Access control system

Use magnetic card and password management to control the entrance and exit of the place. The access rights, channels, and access time of each cardholder can be limited, when the cardholder provides a valid access card. Or enter a valid password, or both are valid, you can allow it.

3. Attendance system

Use the organic combination of access control and computer technology to realize the attendance management of employees and print attendance reports.

4. Parking lot management system

Use computer technology and magnetic card technology to manage the parking lot and automatically register in and out.

5. Security digital inspection system

Whether the security personnel can patrol on time and by line requires scientific management methods. This system gives the best answer to the problem.

Use: Install the electronic address button on the patrol route. The security personnel will carry an electronic patrol stick during patrol. It can communicate with the electronic address button. Touch the electronic address button with the patrol stick to record the patrol time of the patrol staff Before the inspection, define different event buttons as different events, such as: the door is not closed, ** lost, etc., what events are found during the inspection, touch the corresponding event button to record the inspection and find the situation, the management personnel through the computer You can view the inspection situation and print inspection reports to provide a basis for scientific management.

6. Electronic fence

Using 6000-10000 volt pulse high-voltage arming, good security, low false alarm rate, high reliability, wide adaptability, no blind spots, no dead ends and no holes. It is suitable for installation on the basis of the fence iron fence. auxiliary.

3. Function of each equipment

1. Active alarm detector

The active alarm detector is composed of a transmitter and a receiver. The transmitter emits infrared rays, and the receiver receives infrared rays. When someone tries to pass through the infrared alarm control line, the receiver does not receive infrared rays and immediately sends a signal to the host. Realize the alarm.
Many outdoor occasions need to distinguish the size of the infrared blocking object to determine whether it is a person or a bird, so the alarm detectors of a class are double-beam or four-beam detectors, and large objects (such as people) block two or four beams of light Only then will an alarm be generated.

2. Passive alarm detector

Generally installed indoors, people's body temperature is 37 degrees, and will naturally emit infrared rays. Passive detectors continuously detect changes in indoor infrared rays. When someone is found to move, an alarm will be generated.
