SAN JOSE, Calif., Dec. 16, 2010 — JAI Inc. has released color versions of its TM-77X and RM-67X lines of small interlaced CCD video cameras targeted primarily at defense and homeland security applications. The new camera models are the TMC-773 and TMC-775 – NTSC color cameras with ?- and ½-in. sensor formats, respectively – and the RMC-673 and RMC-675 – the PAL versions of these cameras.
They join the six previously announced monochrome models – three with RS-170 interfaces and three with CCIR interfaces – to give customers a full range of choices for traditional analog applications, such as vehicle-mounted systems and other high-end surveillance or situational awareness scenarios. 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 can gradually migrate from one platform to the other as needs evolve.
The TMC-773 and TMC-775 provide standard 768 × 494 NTSC TV output at 30 fps using the Sony ICX258AKL and ICX428AKL CCDs. The RMC-673 and RMC-675 output a PAL-format TV signal at 752 × 582 pixels and 25 fps using the Sony ICX259AKL and ICX429AKL sensors.
The new color cameras provide high sensitivity and image quality with signal-to-noise ratios of better than 50 dB. They also operate with reduced electromagnetic interference 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.
Other standard features include electronic shuttering at up to 1/100,000th of a second, horizontal mirror image capability, and an integrated three-axis control function that can be used to operate motorized zoom lenses, change focus and iris settings, move pan and tilt heads, or any combination of three external control circuits.
For added design flexibility, the company has created a variety of configuration options well suited to outdoor applications. Included is auto level control to automatically adjust gain and shutter settings during changing lighting conditions; conformal coating; pixel blemish compensation; and extended temperature capability for operating in temperatures ranging from -40 to 65 °C.
All three camera housings measure 32 × 42 × 48 mm and support C-mount lenses with adjustable back focus. Board-level versions are also available for large-quantity OEM orders.
