Because the archway metal detector can detect various types of metal objects, it can be used in various places to maintain the safety of the place. However, if you only pay attention to its price 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 an archway metal detector.
1. Sensitivity of the detector
When the archway metal detector detects the metal, it relies on the detector inside to detect the metal. If the sensitivity of the detector is not enough, it will not be able to detect the small metal hidden on the body, so it will not play an effective security and anti-theft role. Therefore, enterprises must understand the sensitivity of the detector when purchasing archway metal detectors.
2. Identification accuracy and false positive rate
When metal objects are detected, the archway metal detector should issue an alarm. However, if the recognition rate of the archway metal detector 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. Therefore, when purchasing an archway metal detector, it is necessary to know the accuracy and false alarm rate of its identification items.
3. The speed of resuming the standby state
Every time someone passes by, the archway metal detector will start the detection. After the person passes, it will resume the standby state so that it will be activated when someone passes by again. If the speed of the archway metal detector returning to standby is not fast enough, then 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 archway metal detector.
In order to ensure the quality of the purchased products, 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, recognition accuracy and recovery of the archway metal detector. Wait until critical issues such as standby speed are considered before purchasing.
