RFEL HALO HD video processing and enhancement system

HALO, a HD video processing and enhancement system from RFEL, provides next-generation, low-power, real-time video processing for image-based surveillance, which is a critical capability for counterterrorism, defence and security, and is not restricted by American ITAR export regulations as it is designed and manufactured in the UK.

Potential applications include: fixed and mobile installations, including covert CCTV monitoring and surveillance, and unmanned aerial vehicles (UAVs). Such systems face common problems, including poor raw sensor imagery and challenging lighting or atmospheric conditions. These challenges have led to an increasing demand for imaging in the infrared and the need for adaptive contrast enhancement to combat poor imagery in challenging lighting conditions.

HALO delivers high-quality, high frame rate, HD video for human or machine interpretation, even in the most challenging of visual environments. HALO’s modular, flexible design makes it suitable for retrofitting/upgrading existing infrastructure, as well as for providing a complete, innovative solution for new designs.

It uses the latest field programmable gate array technology to achieve the high processing bandwidths needed while maintaining low power consumption from a power supply of between 4.7 to 27 VDC. The small form factor of the HALO processor board is housed in a rugged enclosure. The full system measures 105 x 105 x 80 mm and weighs less than 400 g.

HALO offers a range of physical interfaces and supports all major video standards from analog video (eg, PAL/NTSC/S-Video) through to digital standards such as Channel Link and GigE, both with full 1080p. The required interfaces can be configured in the factory to tailor the system to bespoke applications.
