The ThermoVision Sentinel's exclusive auto-focus feature delivers crisp, clear images at the press of a button or whenever fields of view are changed. The system allows you to experience better situational awareness in the wide field of view, while maintaining detailed recognition capabilities in the narrow field of view. A 4:1 continuous digital electronic zoom provides for another level of magnification and fine-tuning for target discrimination purposes.

Sentinel offers a variety of automatic and digital image enhancement features, designed to increase detection capabilities and to reduce the operator workload.

The Sentinel is tested to IP65 and meets NEMA Class 4. It is protected against rain, dust, sand and corrosion, and has been shock tested to 25 g under IEC 68-2-29 and vibration tested from 5-500Hz under IEC 68-2-6. The system also includes an integrated sun shield and high operating temperature specification for hot climate operation.

The Sentinel uses the same imaging payload as the ThermoVision Sentry II. Over 980 Sentry and Sentinel systems have been fielded.
