OMNIDIRECTIONAL MONITORING USING NEAR-INFRARED ELECTROMAGNETIC RADIATION
First Claim
1. A monitoring device comprising:
- an imaging device sensitive to visible and near-infrared electromagnetic radiation;
means for concurrently directing omnidirectional visible and near-infrared electromagnetic radiation onto the imaging device without using any moving parts; and
a plurality of near-infrared illuminators, wherein each near-infrared illuminator is configured to emit near-infrared electromagnetic radiation in a unique region of the area around the monitoring device.

Abstract
A monitoring device includes an imaging device sensitive to visible and near-infrared electromagnetic radiation. The monitoring device is configured to concurrently direct omnidirectional visible and near-infrared electromagnetic radiation onto the imaging device without using any moving parts. The monitoring device also can include multiple sources of near-infrared electromagnetic radiation, which can be sequentially operated to illuminate regions of a monitored area to improve the imaged data. The monitoring device can acquire additional data, such as acoustic data or identification data of a target, and can process the acquired data to detect any targets that may be present and evaluate an alarm condition.
