Security door is one kind of detection device for checking metal from people, it also call Walk through metal detector. Walk through metal detector mainly used in the airport, station and large conference etc. These public places always have large crowd every day, so walk through metal detector can check the metal objects which were hide in the body, such as the firearms and control tools. There are few high-grade walk through metal detector in the market, when people walk through to the security door, it can distinguish the metal object is overweight, excess and not allow shape from someone’s body. If the walk through metal detector happens alarming that means there is someone brings the object not allowed, at the same time it can show where has this object. So security staff can find these objects on time. How to buy a good security door in right way, let me show you for referencing.

The security features in high level that the security door needs high security degree, it is including several factors. For example, uniform magnetic field consistency is the essential for one hundred percent detection rate. And the detection should be enough to detect any dangerous goods, no matter before walk through the door or in the door. Another point is that can check people who through the door under the every speed. It also must distinguish the metal and nonmetallic.

The second function is high recognition. We need to find the one security door which can distinguish a bit dangerous goods. There are some factors must consider. For instance, the magnetic field distribution in consistency, it can able to analysis different metal, it also can immunity the noisy of motor from outside.

The third one is good immunity for noise. Because noise is the one main factor affect security door working normally. The noises have several kinds, such as it they come from motor, electronically controlled locks in the moment. Some noises from power equipment which bring radiofrequency under the voltage. A few noises from close metal detector and metal was removed or in vibration.

The fourth one is proper rate op equipment. You can consider about two point of it. One is electronic board weather build up with SMD technology. Another one is control panel able do function test or not.

In addition to the above features, the efficient walk through metal detector should need to consider about safe when using, it easy to operate and practicability. For these one, here can help you more.
