The SENTINEL LRF (640_9Hz) utilizes a large diameter Germanium lens to extend its observation range beyond 2,500m. The SENTINEL LRF (640_9Hz) is an advanced thermal imaging binocular with a wide variety of tactical, law enforcement, border security and special forces applications. The SENTINEL LRF (640_9Hz) utilizes a high-resolution uncooled thermal sensor to perceive differences in the thermal signature of objects within the field of view.
This device can detect objects at remote distances 24 hours a day, through smoke, fog or camouflage. This device does not produce any audible sounds while in operation.
