Indoor / Outdoor Color Speed Dome Camera

The SPECO CVC-927PTZ Indoor/Outdoor Speed Dome Color Camera combines a responsive pan/tilt movement, auto focus, low-light sensitivity, and a powerful zoom with a rich feature set making it ideal for highly sophisticated surveillance and security systems that require orientation and focus on details. With its weather-resistant design allowing for indoor and outdoor use, and its automatic daytime-to-nighttime viewing functionality, the SPECO CVC-927PTZ is perfect for a wide range of applications including the monitoring of people and property in most any situation.

This integrated PTZ (pan/tilt/zoom) dome camera utilizes a 0.25-inch color Sony Exview HAD CCD (charge-coupled device) image sensor with a 4.1- to 73.8-millimeter varifocal lens with auto focus. The CVC-927PTZ achieves a high resolution with 480 horizontal TVL (TV lines) and up to 768-by-494 effective picture elements via the NTSC signal system. This unit includes an extraordinary 18x optical and 12x digital zoom that allows you can clearly pick out even the most distant objects, and a S/N (signal-to-noise) ratio of better than 60 dB. The SPECO CVC-927PTZ features a wide dynamic range of operation, and includes eight alarm inputs and four alarm for connecting external devices. Already sensitive to light with a minimum illumination of 0.7 Lux in color to infinity, this unit automatically switches to black-and-white in night-mode with a minimum illumination 0.15 Lux in nightmode. If further sensitivity is required, you can remove the IR (infrared) cut filter from the camera, causing the camera to only transmit B/W images and thereby lowering the camera's minimum illumination to 0.01 Lux.

The SPECO CVC-927PTZ has a full pan-angle range of 360 degrees with a tilt range from 0-90 degrees, and includes an auto-flip that rotates your picture 180-degrees at tilt's bottom (for continuous in-motion coverage as something passes beneath the camera). Speeds can range from 0.1 to 90-degrees per second, with a maximum turbo speed of 360-degrees per second panning. This unit features eight preset tours and allows other tours to be programmed with functions and preset locations, as well as eight auto-scans including vector scan, four patterns and eight privacy zones. The CVC-927PTZ also features an onscreen display of camera ID and area name, and an operating temperature of 32 to 122 degrees Fahrenheit. This camera also includes a built-in RS-485 connection for allowing remote operation from many devices such as controllers or DVRs, and runs on 24-volts of DC power with a built-in power-line surge.

Technical Features:

  • Sensitivity: minimum illumination of 0.7 Lux in color and 0.15 Lux in B/W, or 0.01 Lux without IR cut filter
  • Effective pixels: up to 768 by 494 pixels
  • Zoom: 18x optical and 12x digital
  • Pan/Tilt: 360-degrees of panning, 0-90 degree tilt with auto-flip function
  • Dimensions: 5 x 8 inches (diameter x depth)
The SPECO CVC-927PTZ surveillance camera is a reliable, economical and high-quality solution for demanding interactive surveillance. The CVC-927PTZ is designed to work with a wide variety of SPECO accessories such as an optional housing with a heater and blower for extremely cold environments, so you can integrate it in to virtually any system. User's should note, however, that the camera's image sensor may become permanently damaged if exposed to long hours of direct sunlight or halogen light, so the camera should not be mounted or pointed directly at the sun or other bright-light sources. This camera also requires a PC that is not included in this package in order to take advantage of the Internet functionality.

About Surveillance Camera Technical Features
Lux rating is the measurement used to indicate how sensitive a camera is to light, and stands for the level of light reflected off a piece of paper by a candle from one meter away. Thus a sensitivity of three Lux would mean a camera could generate an acceptable picture of a piece-of-paper-sized object that was illuminated by the equivalent of three candles from one meter away. The lower the Lux level, the better the camera's ability to work in low-light conditions. The camera's resolution should be greater than or equal to the resolution supported by the system's recorder or monitor. The S/N, or signal to noise ratio, is an important measure of a camera's quality. A poor camera, low-light conditions or poor wiring causes "noise" which consumes processing power and disk space. A camera with a wide dynamic range is ideal, especially for recording areas in which both indoor and outdoor light are present. CCD (charge-coupled device) sensors provide high-quality images that are less susceptible to noise. CMOS (complimentary metal-oxide semiconductor) sensors offer less image quality, but are usually more cost-effective and energy efficient.

About Pan/Tilt Cameras
A Pan/Tilt Camera has the ability to pan ("move" horizontally), or tilt ("move" vertically). IP cameras often have pan/tilt capability. A pan/tilt camera is ideal for monitoring of situations that need a continual real-time adjustment of the views.
