What does the acronym FLIR stand for?

The acronym FLIR stands for Forward Looking Infra-Red. This technology is utilized extensively in surveillance and reconnaissance operations, particularly in border patrol and security contexts. FLIR systems are designed to detect infrared radiation and produce images based on the heat emitted by objects. This capability allows for effective monitoring in low visibility conditions, such as darkness or obscured weather, making it a valuable tool for border patrol agents to identify unauthorized crossings or monitor vast areas for suspicious activity. The other options presented do not accurately describe this technology or its functionality within the context of border operations.
