Marshall’s Industrial and Security Division (El Segundo, CA) has developed a new series of pinhole lenses designed to protect employees when monitoring high temperature and/or hostile environments. The V-ZPL-HITEMP-A and V-ZPL-HITEMP-B zoom pinhole lenses permit reliable monitoring in temperatures up to 1000°. The V-ZPL12 series pinhole lens, available with motorized or manual zoom control, offers a 4-20mm angle of view and can be used for situations when the camera must be hidden from view. The V-PL150C, V-PL200C, and V-PL300C long focal lenses are designed for covert operations and can be used when looking through walls up to 14.81" thick.
