All prisons orcorrectional institutions have different kinds of protection systems to reduce the numbers of successful escapes, such as:
high and thick walls
Movement Detection Systems
No matter how secure the surrounding is, there is still one dangerous place, where escape attempts are possible: the service entrance for trucks and cars! Normally, every vehicle that enters and
every vehicle that leaves has to be checked by the security guard for the presence of escapees.
This can take an enormous amount of time and effort:
opening all of the boxes
looking inside every hole
looking inside every pallet carrier
It's not unusual that these checks take about half an hour per car. And even after a careful check-up, it is possible for escapees not to get detected.
The MDS can check the vehicle for escapees within seconds. And this with 100% precision.
