The 3920 Series i-dome from Cohu is the most flexible and well-made outdoor surveillance camera you have ever experienced. It is designed for applications that require high performance video, comprehensive features, and 365-days-a-year reliability in all kinds of weather.
The unobtrusive package begins with a high performance day/night camera with integrated zoom lens. Its high-speed positioner can achieve 250° per second in preset mode.
The mechanical assembly is metal, not plastic. The dome is premium acrylic. The legendary Cohu IP67 enclosure means a clean operating environment and low maintenance.
The i-dome camera features a 35x optical zoom range (3.4 mm to 119 mm), with selectable automatic or manual focus.
Automatic Day/Night switching technology assures vivid color images during daylight, and high sensitivity monochrome images after dark.
A high-speed positioner, with 0.1° accuracy, provides 360° continuous rotation and up to 64 user-defined preset positions, each with a two-line, 24-character title. i-dome uses real time computer algorithms to correct for shaking and waving images caused by wind and vibration. The two modes of stabilization settings, 5 Hz and 16 Hz, allow a wide range of vibration compensation.
CohuHD i-dome features the exclusive Cohu multi-protocol control firmware. This means you can incorporate this Cohu camera into an existing control system from other major manufacturers. For traffic management video systems, i-dome can also be ordered with NTCIP control language.
All camera and positioner functions are controlled by the integrated receiver/driver, operable via RS-232/422 serial communications with digital position feedback.
Up to eight tours, each with up to 32 preset positions and dwell time, can be stored in memory. Set up to sixteen sectors in a horizontal plane, each with its own identification title. In addition, eight programmable privacy zones can be set to prevent the viewing of selected scenes.
The i-dome housing provides a low profile installation and looks similar to a luminaire and creates very low wind loading.
The i-dome has been tested to withstand 120 mph (193 km/h) winds with 150 mph (241 km/h) gusts with no structural damage to the camera or support interface.
The dome provides maximum protection against grime and insects. It is rated IP67 and NEMA 4X and, additionally, meets NEMA power,shock/ vibration, and operating temperature standards for TS-2 traffic control systems.
CohuHD delivers years of clean, reliable images and backs it with a world class two year warranty.
