Pelco Spectra IV SL Dome Drive (23x)

Description Specification The Pelco Spectra IV SL Dome Drive (23x) with ¼" EXview HAD image sensor delivers clear images at a resolution of 540TVL. The camera has a varifocal lens with a focal length of 3.6-82.8 mm at f/1.6 and offers a 23x optical zoom and 12x digital zoom. The on-screen compass, tilt, and zoom display feature helps in determining positions when required. Image quality is enhanced with features such as backlight compensation, white balance, and automatic gain control. With 64 presets, the camera offers ± 0.1° preset accuracy and is capable of continuous 360° rotation. The proportional pan/tilt feature decreases pan/tilt speeds in proportion to the depth of zoom, and the camera's variable scan speed ranges from 1-40°/sec. The DD423 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. Zone Blanking will blank 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. The Window Blanking function blocks up to 4 user-defined, 4-sided shapes from being viewed by the operator. Image Sensor and Resolution With ¼" EXview HAD image sensor, the camera delivers crisp and clear images at a resolution of 540TVL. Lens and Zoom Capability Features a varifocal lens with a focal length of 3.6-82.8 mm at f/1.6 and offers a 23x optical zoom and 12x digital zoom. Illumination With a minimum illumination of 0.65 lux at 1/60 sec (color mode) and 0.15 lux at 1/60 sec (black & white mode), the camera produces clear images even in low light conditions. Backlight Compensation Adjusts video gain to correct the exposure when the object being captured is in front of a bright light. Automatic White Balance Adjusts the red, green, and blue colors in the image by taking a white color reference to get the most natural colors. Automatic Gain Control Amplifies the video signal when there is a drop in the signal strength below a specific level ensuring consistently clear pictures. Proportional Pan/Tilt Decreases pan/tilt speeds in proportion to the depth of zoom. The camera is also capable of continuous 360° rotation. Presets and Speeds Supports 64 presets at ± 0.1° preset accuracy and offers 400°/sec pan preset speed and 200°/sec tilt preset speed. A freeze frame button ensures seamless frame transmission between presets. Auto Flip Supports 180° rotation and also allows you to reposition the camera for viewing any object that passes beneath the camera. On-Screen Compass, Tilt, and Zoom Display Helps in determining positions when required. Multi-lingual Menu Allows quick and easy access to the camera via the intuitive multi-lingual menus that can be displayed in English, Spanish, Portuguese, Italian, French, German, Russian, Polish, Turkish, and Czech. AC Line Lock Eliminates timing discrepancies in H/V sync that cause picture interruptions at the switching point. 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 Blocks up to 4 user-defined, 4-sided shapes from being viewed by the operator. Password-protection Password usage restricts access to unauthorized persons.
