Thermography, the use of dogs, or other sensors are some of the most popular methods for the detection of stowaways entering boats furtively. These methods are also used in land border crossings, trails or other places of high illicit emigration activity.
Different methods of detection
Stowaways are well known on the coasts. They usually climb clandestinely on board commercial ships and hide until the ship reaches its destination. Many companies are fined by receiving countries to find dozens of stowaways within their commercial transports.
Not only do they earn expensive fines when transporting numerous stowaways in their vehicles, they also run the risk of suspending the carrier and other attendants. One of the most usual and safe methods to avoid this is the use of trained dogs to sniff out humans.
Other measures against stowaways are light sensors, this can measure light changes that occur within the steel of the ship or container. In addition, it can send wireless signals of movements that occur inside the ship. These signals will be sent to the carrier by a device.
To avoid costly fines, measures have been taken, one of them is the implementation of the thermographic camera, very similar to the surveillance cameras, and located at various points on the boats. These can detect the policeman as hidden as he is from the limited human view, because the thermal cameras detect the radiation and the heat emitted by the stowaway.
Thermal vision cameras are now used with great frequency in the land border crossings, and are able to see what the migration cops can not. Officials will be able to monitor uninhabited land border crossings and detect who crosses illegally, either day or night thanks to these cameras.
