Metal Detector Security
Feel Secured with Metal Detectors
Metal detector security is the first line of defense by many securities and law enforcers in many places. Metal detectors are mainly used in places that need to be secured from any metallic objects like guns and other deadly weapons. Commonly, metal detectors are used in government buildings, prison security, airport security checkpoint, business establishments and courthouse security. The VLF (Very Low Frequency) technology is used in ordinary metal detectors. The most advanced metal detectors uses low radiation x-rays to monitor or detect metals.
Metal detector comes in two different types: the walk through metal detector and the hand held metal detector. The main part of metal detector is the control box, search coil and the shaft. The control box contains batteries, microprocessor that organizes all activities and speaker. It is the brain of metal detectors.
Hand held metal detectors security comes in different types: commercial, all-purpose, professional, beach, gold metal and relic metal. Some people use metal detector to look for some coins, they comb beaches to find treasures.
A hand held type metal detector that is used mostly by law enforcers and security is the super scanner. It detects razor blades, knives and medium-sized pistol. There is a reduction switch in super scanner that minimizes the sensitivity interference. It has also an optional holder and an outsized scan surface. A more advanced type of hand held metal detector is the tactical metal detector. It detects ferrous and non-ferrous stainless steel weapons. Tactical metal detector is water proof, with high impact plastic withstand, need no adjustments and a slip free handle.
Moreover, portable hand held metal detector is normally used to detect metallic weapons that are usually carried by people. Portable metal detector can also check baggage and fabric bags both for non-magnetic and magnetic fields. Portable metal detector security is one of the best choices for buildings and business establishments because of its sensitivity, reliability and with long battery life.
Walk through metal detectors includes electro-magnetic compatibility, control unit and environmental tolerance, assurance of quality control and an interface for operators. Walk-through security metal detector has a low rate false alarm, consistent detection, high target selections and a two-way directional system. Walk-through security metal detectors offers quick and effective processing.
There are two types of walk-through metal detectors; the single-zone and multi-zone walk through metal detector security. Single-zone walk through metal detectors are widely used in public environments and schools. It has a medium sensitivity that best suit for security in those places. Single-zone metal detectors are designed to be used in cruised ships to fit the applications on decks. This includes electronics that are water proof to prevent from humidity.
Most walk-through metal detectors security is based on different technology. Metal detector security in digital technology provides better target detection coverage which is widely used in airports security. Those with microprocessor metal detectors can automatically remove electrical interference with x-ray device. In prisons, heavyweight metal detector is used to prevent visitors from carrying deadly weapons or metals that can be used by prisoners to escape. It can detect various types of weapons and metals.
Advanced metal detectors uses low radiation x-ray to detect metals. Better to use metal detectors to assure the security of your place. There are some metal detectors that are cheap and only cost $70.
