TIMESTAMPS

Dust. Smoke. Humidity. Airborne sand. See right through them in daytime or at night with the Amber/Raytheon Argus Sentry Day/Night Surveillance System.

Argus Sentry is ideal for paramilitary and military surveillance applications such as border security, monitoring of oil platforms, vessel traffic management, and aircraft detection.

Argus Sentry is a turnkey remote monitoring system that integrates Amber/Raytheon RADIANCE infrared cameras together in weatherproof enclosures. Multiple remote camera sites can be controlled and monitored from a central control station via wireless communication links.

Argus Sentry provides excellent passive night vision in cold environments as well as hot, humid climates. The detection range of the infrared camera depends on the lens used. Background temperatures, atmospheric conditions, clutter and object temperature can affect range.

A dual focal length lens, switchable between a 7.4 and 2.2 degree field-of-view, is standard with Argus Sentry. Longer and shorter focal length lenses are also available to support other requirements.

An optional laser range finder provides the capability to overlay object distance data on the thermal or visible video image.
