door frame metal detector manufacturers

Door Frame Metal Detector is divided into multiple zones. Each zone represents a specific area of the body, typically from head to toe. Each zone consists of both transmitter and receiver coils. The transmitter emits a magnetic field, while the receiver detects any disturbances in this field caused by metallic objects. When metal is detected in one or more zones, the system activates an alarm to alert security personnel. The alarm can be visual, such as flashing lights, and/or audible, such as a sound or voice message. Door frame metal detectors often come with adjustable sensitivity settings. This allows security personnel to customize the level of sensitivity for different environments and scenarios, reducing false alarms while still detecting potentially dangerous objects.
