1、 Metal detection security checkpoint
Metal detection security gates are the most common and basic type of security equipment. It utilizes the principle of electromagnetic induction to detect gold exhibition items carried by the human body by emitting electromagnetic waves. When the detected personnel pass through the security checkpoint, if they carry gold exhibition items, these items will interfere with electromagnetic waves, causing the security checkpoint to issue an alarm signal. The characteristics of metal detection security gates are fast detection speed, simple operation, and low cost. They are widely used in crowded public places such as airports, stations, and large conferences.
2、 X-ray security checkpoint
X-ray security checkpoint is an advanced security equipment that utilizes the ability of X-rays to penetrate objects and detects items carried by personnel through computer-generated images. The X-ray security door can clearly display the internal structure of the detected item, including its material, shape, size, etc. The characteristics of this security checkpoint are high detection accuracy and the ability to detect items hidden inside clothing or backpacks, but the cost is high and the operation and maintenance are relatively complex. X-ray security gates are mainly used in places with high security requirements, such as airports, customs, etc.
3、 Liquid security checkpoint
Liquid security gates are mainly used to detect whether liquids are safe, in order to prevent the carrying of dangerous or prohibited goods. It uses specific spectroscopic analysis techniques to analyze the chemical composition of liquids and determine their safety. The characteristics of liquid security gates are fast detection speed and high accuracy in identifying liquid types, but due to technological limitations, they may not be able to detect all types of dangerous goods. Liquid security gates are commonly used for security checks in places such as stations, subways, concerts, etc.
4、 Intelligent security checkpoint
The intelligent security checkpoint combines various security technologies, such as metal detection, biometric recognition, and personal identification verification, to achieve integrated security functions. The intelligent security checkpoint captures the facial features of the detected personnel through high-definition cameras and compares them with other identification information to verify the authenticity of the personnel's identity. At the same time, the intelligent security checkpoint can also monitor personnel's temperature in real time, detect carrying items, etc., providing multi-faceted support for security checks. The characteristics of intelligent security gates are powerful functionality, high level of intelligence, and easy operation, making them suitable for places with high security requirements.
5、 Temperature measurement security door
The temperature measurement security checkpoint is mainly used for rapid screening of human body temperature to detect individuals with fever and prevent the spread of the epidemic. It adopts infrared temperature measurement technology to measure the body temperature of the tested person in a non-contact manner and display it in real time on the screen. When the temperature of the person being tested exceeds the set threshold, the temperature measurement security door will issue an alarm signal to remind the security personnel to take action. The characteristics of temperature screening doors are fast detection speed, high accuracy, and easy use, suitable for places that require large-scale temperature screening, such as stations, airports, schools, etc.
In summary, different types of security gates have their own characteristics, and metal detection security gates are suitable for quickly screening metal items; The X-ray security checkpoint can provide high-precision object detection: the liquid security checkpoint focuses on liquid security inspection; The intelligent security checkpoint integrates multiple functions and provides multi-faceted security support, while the temperature measuring security checkpoint is used to quickly screen body temperature and prevent the spread of the epidemic. In practical applications, the appropriate type of security checkpoint should be selected based on the characteristics and safety requirements of the location.
