HIKMICRO FB21 Firefighting Thermal Camera Model: FB21 The HIKMICRO FB21 firefighting thermal camera is specifically engineered for firefighting, search and rescue, and emergency response operations. Built to perform in smoke-filled, low-visibility, and high-temperature environments, the FB21 delivers clear thermal imaging that enables firefighters to quickly locate victims, identify hot spots, and maintain critical situational awareness during incidents. Equipped with a high-sensitivity thermal detector optimised for fireground use, the FB21 produces crisp, high-contrast thermal images displayed on a large, high-brightness LCD screen. This ensures dependable visibility even in extreme lighting and heavy smoke conditions. The streamlined interface and dedicated firefighting imaging modes allow for fast, intuitive operation under pressure, helping reduce distractions when every second counts. With a wide temperature measurement range suited to firefighting environments, the FB21 supports rapid identification of heat sources, fire progression, and concealed hazards behind walls, ceilings, and structural elements. Its rugged, heat-resistant housing is designed to endure impact and water exposure, making the FB21 a reliable and durable tool for frontline firefighting and rescue operations.
