Interlaced video camera


JAI has announced the release of a new line of monochrome interlaced video cameras designed to provide higher image quality, expanded features, and increased design flexibility for applications utilizing traditional RS-170 (EIA) standard video interfaces. The three new camera models - the TM-770, TM-773NIR, and TM-775NIR - are aimed primarily at defense and homeland security applications, but can be used for a variety of industrial applications as well.

Although identical in outward appearance, the three different cameras give designers a choice of pixel sizes and optical formats ranging from the 2/3" ICX422AL sensor in the TM-770, to the 1/2" ICX-428AL in the TM-775NIR, to the 1/3" ICX258AL in the TM-773NIR. The latter two sensors provide added sensitivity to near-infrared light as indicated by the "NIR" designation in the model name. With the same physical footprint for all three models, designers can easily find the right model to fit the optics in their current system designs, or gradually migrate from one platform to the other as needs evolve.

Operating at the standard 768 x 494 TV resolution (30 fps), the new cameras provide improved image quality versus older interlaced models (signal-to-noise ratio >55 dB) and reduced EMI emissions measured at 12 dB below the maximum limit for Class A products. A single 15-pin connector is used for power, camera control, and video output, making installation clean and simple. All camera features can be controlled via RS-232 commands over this single interface cable.
