Door Frame/Hand Held Metal Detector
Door Frame/Hand Held Metal Detector
The improvement of security measures is becoming a necessity these days, be it at the mall or entering a hospital. New and upgraded metal detectors are introduced in the market from time to time. They are used at prisons, courthouses, schools, military facilities, and airports.
Security personnel are geared with hand-held metal detectors while the DMFM or Door Frame Metal Detector is installed for walkthroughs.
Anyone passing through the entrance has to undergo a brief check before they are let into the premises. Facilities, organizations, and institutes use metal detectors to detect or identify metal objects that may pose as weapons.
Many potential threats have been eliminated or kept at bay due to the presence of these detectors.
Get the best Door Frame Metal Detectors (DFMD)
A Door Frame Metal Detector, also known as a “walk through” metal detector, helps detect metallic objects on a person’s body. The different types are as follows:
● Single zone DFMD
This door frame has a single-sided sensor that can detect only one zone on the body. This type of DFMD is used in smaller facilities where risk and threats are minimal.
● Multi-zone DFMD
This door frame has multiple sensors on both sides that can detect metals present on either side of the person. The multi-zone DMFD is used at more extensive facilities where safety and security are required at high priority. A range of objects from harmful to harmless metals such as handguns, knives, coins, and keys are detected.
How to evaluate and choose the best DFMD
● Uniform detection – A well-designed detector will provide uniform detection across the different zones of the body. Dead spots or zones where high and low sensitivities are detected indicate a poorly designed DFMD.
● Electromagnetic and electric interference – If other objects or instalments nearby interfere with the detector, the device is low in quality. A high-quality DMFD comes with efficient noise inhibition software algorithms. This software enables the device to cancel out the noise from various sources like flickering light bulbs, photocopiers, two-radios, etc.
● Continued activation – the DFMD should be active throughout operations. It should not present circuitry deactivation at any time. Installing one that pauses detection in an unmanned area can be a safety risk for the members at that facility
