The Pelco Spectra IV SL Dome Drive (27x) is a high-performance day/night camera with ¼" EXview HAD image sensor that delivers 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 a 27x optical zoom and 12x digital zoom. With 128x wide dynamic range and low light noise reduction function, the camera provides high-quality images even in low light conditions. The on-screen compass, tilt, and zoom display feature helps in determining positions when required. Image quality is enhanced with features such as lowlight noise reduction, backlight compensation, white balance, and automatic gain control.

With 256 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 DD427 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. A Window Blanking function blocks up to 8 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 3.4-91.8 mm at f/1.4 and offers a 27x optical zoom and 12x digital zoom.

Illumination

With a minimum illumination of 0.55 lux at 1/60 sec (color mode) and 0.00018 lux at ½ sec (black & white mode), the camera produces clear images even in low light conditions.

Wide Dynamic Range

Balances the bright and dark portions of a scene to provide high-quality images even in low light conditions.

Low Light Noise Reduction

Reduces video noise in low light conditions to produce high-quality images.

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 256 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 8 user-defined, 4-sided shapes from being viewed by the operator.

Password-protection

Password usage restricts access to unauthorized persons.

Motion Detection

Triggers an alarm when motion is detected and allows you to define 4 motion detection areas for a preset.

Park Time

Allows the camera to start a specified operation (scan, preset, or pattern) after a defined period of inactivity. Park time can be configured from 1 to 720 minutes (12 hours), or set to 0, which disables this feature.
