Know How Hand Held Metal Detectors Help in Finding Security Threats

No business or manufacturing company can take the risk of losing their finished good and raw material. But in Australia and worldwide, warehouses and large companies have seen losses due to employee theft. Or sometimes, security guards find people carrying unwanted items that can pose a threat to lives and properties.

These cases you read above can be easily solved using metal detectors. It can find you hidden metal objects. Any metal object within the electromagnetic field can be detected with such devices.

How Does It Work?

Operating a metal detector is simple. As soon as you hire security guard professionals in Brisbane, you will find they move the device across the areas you wish to search for lost items or suspect threats.

Advanced the metal detectors, quicker the search will be. Here is the brief discourse of how metal detectors work:

• Frequency: Security professionals carry the device up to the location where it can reach a certain frequency. Higher the frequency, better it can determine the targets.
• Use of Electromagnetic Field: It detects the presence of metallic objects. There are 2 primary components of a hand-held metal detector wand - a transmitter coil to create an electromagnetic field and receiver coil to detect electromagnetism. The electromagnetic field generates around the transmitter coil and extends up to 20 cm from the security wand. Professionals from security guard companies in Gold Coast run the wand across the body of the people trying to enter a location.
• Alert the User Upon Detection: A good quality hand held security metal detectors come up with various alarm indicators, including selectable audio alarms, vibration, Visual LEDs. Professionals employed in malls, corporate buildings or apartments as security guards use self-calibrating metal detectors that do not need to adjust the sensitivity.

Components of Metal Detector

The components of the metal detectors make them capable of discriminating between different target types. Find them below:

• Battery: It provides a detector with the power to perform.
• Search coil: The search coil of the detector transmits the electromagnetic field deep into the ground and receives the of the electromagnetic field.
• Transmission of Electromagnetic Field: The transmitted electromagnetic field energises targets and enables them to get detected.
• Receiving of the Electromagnetic Field: The electromagnetic field is received from the energised target.
• Target Response: Upon detecting a good target, the metal detector will produce an audible or visible response.

Hand held metal detectors are highly affordable nowadays, and they are increasingly used at different checkpoints and establishment to deploy better security. With a good quality hand held metal detectors, it is possible to detect weapons, knives, foil-wrapped drugs or other metallic objects.

However, it's a fact to remember that screening people for weapons requires no body contact with the metal detector. The operator doesn't need to touch the subject. Even, hand held motion detectors do not raise the alarm if you hold it at a certain point. The operator has to move the scanner over the metal object to detect it.
