Thermal Surveillance Cameras

Vumii (Atlanta, GA) has added four thermal camera lines to its imaging solutions portfolio: CompactSec™, EyeSec™, DualSec™, and RangeSec™. The IP-enabled CompactSec thermal camera is available in three models: 8.5mm lens for 65° field of view; 19mm lens for 28° field of view; and 35mm lens for 15° field of view. The EyeSec, a line of uncooled thermal cameras, has a wide variety of lens and resolution configurations, including a 15-100mm continuous zoom model. The camera provides thermal video through darkness, light fog, or smoke. The EyeSec line features IP or analog communication options with 320 x 240 25μ or 640 x 480 17μ resolution. The DualSec dual-video (thermal and visual) channel pan tilt camera system allows mediumrange observation and detection. The RangeSec imager, a high-sensitivity, cooled midwave (3-5 μm) thermal camera, utilizes a 19mm to 275mm continuous zoom (29° to 2° field-ofview) or a 47.5mm to 687mm continuous zoom lens (12° to 0.8° field-of-view).

Color Sensors

TAOS (Plano, TX) has announced the TCS3x71 and TCS3x72 Series of Digital Color RGB and Proximity Sensors. When coupled with IR LED, the sensors also provide proximity detection within a range of lighting conditions and through a variety of attenuating materials. The TCS3x72 Series is the industry’s first color sensor with an IR blocking filter integrated directly on-chip and localized only to the color sensor photodiodes. In addition, the on-chip IR blocking filter enables the devices to perform ambient light sensing (ALS).

Epoxy

The Polymer System EP37-3FLF from Master Bond (Hackensack, NJ) resists cryogenic temperatures and thermal cycling. The two-component epoxy, which features a low exotherm, functions as a potting, encapsulating, and casting system, especially where wider cross section thicknesses are specified. Serviceable over the range of 4K to 250°F, EP37-3FLF cures at room temperature in 2 to 3 days or faster at elevated temperatures. The product offers a non-critical 1-to-1 mix ratio by weight or volume, and a low mixed viscosity of 1,400 to 1,500 cps. Additionally, users can work with a 100 gram mass of the adhesive at room temperature for up to 90 minutes.
