Product Description


The SPECO CVC-724EXTP/W H.E.A.T. Color Vandal Resistant Dome Camera with 4-9mm Auto Iris Varifocal Lens (White) is great for any outdoor application. Constructed with housing with a high-impact dome cover and durable metal base designed to withstand a blow from a 10-pound sledgehammer, and rated at IP66 for weather protection, this camera can be placed virtually anywhere. Designed to provide a high-resolution picture even in very low-light conditions, the SPECO CVC-638/170 is a great addition to any video surveillance system, especially in applications subjected to extremely inclement weather conditions or where vandalism is of concern.

This vandal resistant dome camera utilizes a 0.33-inch color Sony HAD CCD (charge-coupled device) image sensor with a four- to nine-millimeter varifocal lens. The CVC-638/170 has a very high resolution of 470 horizontal TVL (TV lines), and achieves a S/N (signal-to-noise) ratio of 50 dB or better. Highly sensitive to light, this camera can receive a usable picture with a minimum illumination of 0.03 Lux for very low-light viewing. The SPECO CVC-638/170 operates on the NTSC TV scanning system, and includes a standard BNC (Bayonet Neill-Concelman) composite video output. This unit runs on 24-volts AC power, and can operate in temperatures ranging from -20 to 122 degrees Fahrenheit. The CVC-638/170 includes a built-in auto-iris with an automatic electronic shutter with speeds ranging from 1/60 to 1/100,000 of a second.

Technical Features:

  • S/N ratio: better than 50 dB
  • Sensitivity: minimum illumination of 0.03 Lux
  • Weather protection: IP66 rated
  • Horizontal resolution: 470 TVL
  • Operating temperatures: -20 to 122 degrees Fahrenheit
  • Dimensions: 5.1 x 3.3 inches (diameter x depth)
The SPECO CVC-638/170 camera provides you with a high-quality color picture from a camera that can go virtually anywhere, and deserves serious consideration as an addition to any severe-weather security system. The IP66 (Ingress Protection) rating means this unit has a protection level of six against solid-body ingress, and a protection level of six against the ingress of water. Six is the top protection level against solid bodies, meaning the CVC-638/170 is certified dust proof. Six is the third highest protection level against water, meaning this unit will protect your camera against strong jets of water from any direction. Users should note that the CCD 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.

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.
