SkyWatch Frontier
The SkyWatch Frontier was developed with the intention of being deployed with our military forces and, as such, provides optional ballistic capabilities for those areas in which enemy activity is at its highest. Due to this inherent design, the SkyWatch Frontier can meet the rigors of expeditionary missions not only for the military, but for border patrol and high level security arenas as well.

The Park Police also utilized their own SkyWatch™ mobile surveillance towers to assist with crowd management and surveillance [at the Independence Day celebrations in our Nation’s capital]. . . . In addition to celebrations on the National Mall, ICx products and services support security operations at other national icons across the United States, including the Statue of Liberty and the Hoover Dam.
