The security sector has evolved at a significant pace over the past decade or so and disruptive new products are perhaps quite rare to come across. However, it appears that Defense Technologies (OTC:DTII) has come up with a product that has disrupted the protective security sector.

The product in question is a zero radiation full-body scanner and it could be a good idea for investors to consider taking a closer look into it. The product in question is known as Passive Portal and the zero radiation product deploys advanced passive sensors to detect the common metals which are found in firearms, knives and other weapons. The product can help in detecting these weapons without the necessity of emission of any kind of electromagnetic radiation.

In this regard, it should be noted that a passive sensor is a kind of electronic device that provides responses to input directly from the physical environment in which it is placed. In addition to that, it ought to be noted that passive sensors are already deployed in a range of other products like thermometers and thermostats as well as in common smoke detection devices.

The Passive Portal from Defense Technologies would help in the detection of the presence of weapons in a non-invasive way. Considering the fact that the product has already managed to disrupt its sector, it could be a good move for investors to keep a closer eye on the Defense Technologies stock.
