- Receiver / Enclosure
- Pressurized Integrated Optics Cartridge
- Day/Night Camera (1/4" CCD)
- Pressurized Dry Nitrogen to 10 psig
The camera optics and electronics inside the self-contained, sealed unit are protected from moisture and airborne contaminants. Dry nitrogen pressurized to 10 psig keeps the cartridge free from internal condensation and corrosion. Any drop in pressure, temperature, or humidity beyond factory-set, acceptable limits causes the sensors in the cartridge to send out an alert. The sensors also allow for instant on-screen display of temperature, pressure, and dew point.
With die-cast, extruded, and sheet aluminum construction and stainless-steel hardware, the positioning system is suitable for both indoor and outdoor applications. And being gear-free, it requires minimum maintenance. Capable of operating in 90mph winds, the Positioning System can withstand wind velocities up to 130mph, and can function in temperatures ranging from -40 to 140° F (-40 to 60° C). Within 2 hours of starting up, the system can de-ice and be operational from a temperature of -13°F (-25°C). With the help of power-up recovery mode, the user can decide which operation of the system will be resumed when the power comes back on. It also includes a built-in thermostatically-controlled heater window defroster/defogger, and insulation bracket to maintain to internal temperature of the unit. A sun shroud protects the system from the direct rays of the sun.
A 1/4" EXview HAD image sensor in the DD4CBW35 day/night camera offers a high resolution of 540TVL with a 2:1 interlace scanning. With 128x wide dynamic range, the camera provides high-quality images even in low light conditions. It has a varifocal lens with a focal length of 3.4-119 mm at f/1.4 and a 35x optical zoom.
The autofocus feature automatically focuses the camera on to the selected object or area. Auto white balance takes a standard white color reference to adjust the RGB (red, green, and blue) colors to produce good quality images in a wide range of lighting conditions. Automatic iris control adjusts the amount of light passing through the lens. AC line lock is used to eliminate timing discrepancies in H/V sync that cause picture interruptions at the switching point. In addition to image enhancement, the camera also has electronic image stabilization that counters the vibrations caused by moving traffic or strong winds. The camera eliminates interference from the cage by automatically focusing through the cage bars at medium to high zoom.
Zone blanking blanks out an entire area or zone (which is set by a system operator) to eliminate any unnecessary video information from being processed, thus decreasing video traffic over a network. Up to 8 zones can be programmed to output blank video for areas not requiring video surveillance.
The blank video output can be with or without labels; each label has a maximum limit of 20 characters.Window Blanking function blocks up to 4 user-defined, 4-sided shapes from being viewed by the operator.
Variable pan/tilt speeds range from 0.5-40°/sec in manual pan and 0.5-20°/sec in manual tilt. The system has pan preset and turbo speeds of 100°/sec in wind speeds of 50mph and 50°/sec in the 90mph wind speed. Capable of 360° continuous pan rotation, the pan/tilt head has a tilt preset speed of 30°/sec and a tilt ranging from +33 to -83°. The 64 programmable preset positions have a preset accuracy of 1/4°.
With on-screen, user-friendly menus, the system is easy to program and operate. The easy-to-install system has quick and simple electrical connections with 2 power source connections made at mount location with wire splices and 1 ground wire splice. The ES30P System has certifications/ratings such as CE, Class B, FCC, Class B, C-Tick, S Mark for Argentina, and is UL/cUL-listed. The system also meets NEMA Type 1, IP40 standards.
