What problems should you understand when purchasing a metal detector door
2022/09/28
Because metal detector doors can detect various types of metal objects, they can be used in various places to maintain the safety of the place. However, if you only pay attention to the price of the metal detector door without considering the quality when purchasing, it may also lead to insensitivity to metal detection. Let's take a look at the key points to understand when purchasing metal security doors.
1. Sensitivity of the detector
When the metal detector door detects the metal, it relies on the detector inside to detect the metal. If the sensitivity of the detector is not enough, it cannot detect the small metal hidden on the body, so it cannot play an effective security and anti-theft role. Therefore, enterprises must understand the sensitivity of the detector clearly when purchasing metal security doors.
2. Identification accuracy and false positive rate
When metal objects are detected, the metal security gate should sound an alarm. However, if the recognition rate of the metal detector door is low, it will not only issue an alarm when it encounters metal, but also sometimes sound an alarm when it encounters other objects. , which will affect the speed of security inspection and increase the workload of the staff, so when purchasing metal security doors, it is necessary to know the accuracy rate and false alarm rate of its identification items.
3. The speed of resuming the standby state
Every time someone passes through, the metal security gate will start detection. After the person passes, it will resume the standby state so that it can be activated when someone passes through again. If the speed of the metal security gate returning to standby is not fast enough, the number of people who pass through will be given within a certain period of time. There will be very few, so when purchasing, it is necessary to know how many people can pass through the allowed time without affecting the detection performance of the metal detector door.
In order to ensure the quality of the purchased metal detector door, the company must first find a security inspection door manufacturer with reliable quality, and then conduct detailed consultation and communication with the staff of the manufacturer to understand the detection sensitivity and recognition accuracy of the metal detector door. As well as the key issues of restoring the standby speed, etc., before purchasing.
