Several explosives detecting technologies are now available or in development that could aid in the security of systems. While these technologies show promise in some situations, their environmental limits must be recognised, and their application adapted to individual systems. With several conventional explosive hazards, proven technologies such as handheld, desktop, and kit based trace detection systems, x-ray imaging systems, and canines have proved good detection capacity, and some are in use. While newer technologies like as explosive trace portals, improved imaging technology, and standoff detection systems are available, they are still in the early phases of development, and more operational experience would be required to evaluate how well they will function if deployed. When implementing any of these technologies to secure, it's critical to consider both the underlying technology' inherent limits as well as the security implications. Other factors to consider include throughput, portability, and durability and station physical space constraints.
