The Zistos through-the-wall system is ideal for hostage barricade scenarios as well as explosive breaching operations. Like many of our systems, the TTW was developed at the request of and with the cooperation from Law Enforcement. The system contains specially designed hand drill and cutting tools, cameras and display that allow observation into an adjacent interior room through a sheetrock wall.
