Toshiba IK-645A High Resolution Day/Night Color Camera Specifications
The Toshiba IK-645A High Resolution Day/Night Color Camera is a cost-effective, high-resolution solution ideal for variable-lighting surveillance applications. This camera comes with DSP (digital signal processing) technology, and automatically switches from daytime color to B/W (black-and-white) for nighttime viewing. Designed to provide a consistently good image even in low-light conditions, the Toshiba IK-645A is a great addition to any video surveillance system, especially in round-the-clock applications.
This day-and-night CCTV camera utilizes a 0.33-inch interline-transfer CCD (charge-coupled device) image sensor with a standard CS-mount lens that employs 768 by 494 effective pixels. The IK-645A provides a high resolution of 480 horizontal TVL (TV lines), and has a great S/N (signal-to-noise) ratio of 50 dB or better. This camera features multi-zone backlight compensation, automatic electronic shutter and gain controls that are all automatic, and features a sensitivity to light that allows a usable picture at a minimum illumination of 0.2 Lux. The Toshiba IK-645A operates on the NTSC video format, is dual-voltage compatible running on either 24-volts AC or 12-volts DC power, and can operate in temperatures ranging from 14 to 122 degrees Fahrenheit. This unit is mounted by a 0.25-inch threaded screw, holes for which are provided on both top and bottom.
Technical Features:
- S/N ratio: better than 50 dB
- Minimum illumination: 0.2 Lux in B/W
- Effective pixels: 768 by 494 pixels
- Horizontal resolution: 480 TVL
- Operating temperatures: 14 to 122 degrees Fahrenheit
- Dimensions: 2.74 x 1.97 x 4.56 inches (W x D x H)
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.
