Anew body-scanning machine, the ProVision Automatic Threat Detection (ATD) system, which is marketed by security detection product supplier Hissco, is able to detect both metallic and non- metallic concealed objects at security checkpoints.
The machines are made in Tampa, Florida, by security and detection systems manufacturer L3 Communications. Hissco is L3 Communications-authorised and an exclusive distributor for sub-Saharan Africa.
The machine was designed to stop theft and unauthorised entry or exit of foreign objects in the workplace or through airport security.
Hissco director Greg Dixon says different industry segments, such as the commercial, manufacturing and mining sectors, have shown an interest in using the ProVision ATD machine.
He notes that, owing to its ability to detect any type of material, the machine is particularly useful in the manufacturing industry, where expensive and hard-to-detect products are being stolen.
“The machine is able to detect very small quantities of the composition of any material, such as ceramics, wood, glass, metallic and nonmetallic materials on a person’s body.
“This is particularly useful to prevent the unauthorised removal of companies’ sensitive intellectual property, perhaps in the form of flash drives, CDs, DVDs or documents,” says Dixon.
He adds that it is also suitable for the mining industry as a means to eliminate the theft of explosives.
“Mines are in need of such security measures to pick up when explosives are being stolen. The quick processing time – seven seconds for a complete multidirectional scan – enables the operator to scan up to 600 people an hour.
“Besides its speed and accuracy, the machine also offers better safety than most body scanners that are currently on the market.
“Most machines are based on X-ray technology. The ProVision does not use X-ray technology, but rather harmless radio wave technology. The energy given off by this machine is 10 000 times lower than a three-second phone call on a cellphone,” he explains.
The ProVision ATD system is built for high checkpoint throughput. A quick scan provides checkpoint personnel with the data needed to confidently pass an individual through a checkpoint.
“The machine is very simple to operate. It features a male scan option and a female scan option, because of the slightly different algorithms for each body type,” says Dixon.
The ATD system highlights any foreign objects that should not be there by placing a yellow block over the area where it is located, on a sexless mannequin representing the human body.
However, the Viewed version of the machine enables the operator to see a more defined three-dimensional (3D) picture of exactly what object is being hidden. Once the machine has completed a scan, the machine creates a 3D view of the body on a screen on the control panel. This can then be rotated and manipulated by the operator.
The operator can quickly and effectively react to the situation, as he or she will immediately be able to identify if the object is harmful to the carrier or to others.
The ATD system is easy to maintain and uses electricity, which allows for easy connection and operation.
