The Pelco Spectra IV SE SD427-HPE1 Heavy-duty Back Box and Lower Dome includes a heavy-duty environmental pendant back box, a clear bubble, and a 27x day/night camera.
The aluminum environmental pendant back box with thick shroud and dual wall construction secures the camera and features built-in memory, sun shield, fan, heater, an integrated passive UTP circuit, 2 auxiliary outputs, and 7 alarm inputs.
The clear lower dome ensures high optical clarity and has an operating temperature of 32-122° F. The polycarbonate clear bubble in the dome is injection molded and is 3.5 times stronger than earlier heavy-duty bubbles. The aluminum trim ring has 2 barrel-type key locks to make the system more tamper-resistant.
With a 1/4" EXview HAD image sensor, the DD427 Day/Night camera offers clear images at a resolution of 540TVL. The camera has a varifocal lens with a focal length of 3.4-91.8 mm at f/1.4 and offers 27x optical zoom and 12x digital zoom. With 256 presets, the camera offers ±0.1° preset accuracy. The on-screen compass, tilt, and zoom display feature helps in determining positions, and window blanking allows the user to set up to 8 user-defined 4-sided privacy areas. These zones can either be labeled with a maximum of 20 characters each or set to output blank video. With 128x Wide Dynamic Range, the camera provides high-quality images even in low light conditions.
Proportional pan/tilt feature decreases pan/tilt speeds in proportion to the depth of zoom and the camera's variable scan speed ranges from 1 to 40°/sec. The camera also has a 'freeze frame between presets' feature that ensures a seamless frame transition between presets. Password-protection ensures that settings cannot be tampered by unauthorized persons.
The auto-focus feature automatically focuses the camera on 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.
With certifications/ratings such as CE, Class B, FCC, Class B, UL/cUL-listed, C-Tick and S Mark for Argentina, the system also meets NEMA Type 1, IP40 standards and U.S. Patents D457, 904 and D460, 978.
