Government infrastructure facilities such as water treatment facilities, power plants, laboratories, and the like may be targets for terrorist attacks. Similarly, oil pipelines, power grids, warehouses, factories, laboratories, and the like in the commercial sector may be targeted by terrorists or persons engaging in industrial espionage and sabotage. When these facilities are remotely located, the limited or nonexistent power sources in the area may prevent or severely restrict the employment of cameras, sensors, and other intelligence, surveillance, and reconnaissance (ISR) devices. Thus, there is a need to overcome these limitations while providing around-the-clock persistent support and similar capabilities.

A multi-sensor camera system draws power from the power lines to which it attaches.

One innovation to address this demand is a remote sensor system. Most available sensor systems have two primary drawbacks: limited power and limited line-of-sight communications. These drawbacks limit the effectiveness of such systems. Power limitations limit the ability of these systems to operate reliably and provide around-the-clock surveillance. Existing line-of-sight communications limitations reduce the ability of such systems to transmit sensor data to remotely located end users in an effective manner.

The High Voltage Power Line MultiSensor (HVPM-S) system provides a remotely operated and controlled system that can be deployed around the world, and operate and survive around the clock to provide P-ISR capabilities.

The multi-sensor system can be attached to a high-voltage power line, draw power from the power line inductively, and convert the power to lower voltages and direct currents for operating cameras, sensors, a processor, and communications equipment that provide persistent ISR capabilities. The multi-sensor system can detect and track targets in detection regions, and transmit such detection data and other data from the camera and sensors to a remote operator who can initiate response actions and send control instructions to the multisensor system from the remote location.

The base induction power system provides a steady power supply capable of driving a number of digital still and video cameras in visible, infrared, and other wavelengths, along with various acoustic devices and other sensors. Additionally, the device can transmit data via a variety of methods, including cellular telephone networks.

Safety and security monitoring applications are numerous across multiple industries. Examples include monitoring city streets or remote stretches of highway, site security, wildlife management, construction project monitoring, and energy infrastructure security.
