This break-through technology makes EZ Track Domes incredibly effective in protecting parking lots, storage yards, warehouses or any large area in need of hands free surveillance.

Those cameras will operate in low light, they don’t appear to have any thermal capabilitys, many areas along the border have no background light, thermal capabilitys are necessary in those areas. Those cameras are limited to 3000 feet, remote border areas require much greater distance to be effective.
