RAVEN
(Remote Articulated Vision Enhancement Node)
The Raven (Remote Articulated Vision Enhancement Node) is a light weight tactical surveillance system utilizing a high-precision, low-power tactical pan/tilt system for electro-optics positioning. The color camera provides color and NIR vision with 36x optical zoom, while a thermal camera provides an uncooled 640x480 17μm sensor with a fixed 60mm lens. Both optics are housed in nitrogen filled, IP-67 housings. A sealed NEMA-4X rated video transmission box provides full-resolution MPEG-4 video and transmission over a frequency-adjustable, COFDM mesh radio. The system may be powered via 120-240 VAC, or 24 VDC from man-portable battery and flexible solar panels can also be specified. This combination of solar and battery power sources allow for quick deployment of RAVEN in remote areas, while providing long periods of autonomous field operation.
Options include a variety of lens configurations—both cooled and uncooled thermal sensors, and tactical laser modules for illumination or targeting.
