According to one aspect, a method for remote monitoring of electrical equipment includes acquiring a set of data points, each data point representing a temperature associated with a piece of electrical equipment or a component thereof, assigning each data point to one or more groups of data points, and defining an alarm metric for each group. Each group's alarm metric may be defined independently of other group's metrics. The defined alarm metrics are used to determine the health of the electrical equipment. The data may be determined from virtual probes within an infrared sensor and/or received from RFID devices containing temperature sensor, which are attached to or near the equipment to be monitored, for example. The methods described herein do not require conversion of sensor data into temperature values, and thus obviate the need for expensive sensors and/or computationally demanding conversion, compensation, and calibration routines.

A device providing a temperature control and/or monitoring and a method for use of the device are disclosed. In the disclosed method and device, a controller receives a minimum temperature value and a maximum temperature value of a temperature range to be measured. The controller correlates a known output signal range of a temperature sensor to the temperature range to be measured. Further, the controller receives an output signal from the temperature sensor, and generates a measured temperature value based on the output signal of the temperature sensor.

A remote monitoring system can include a plurality of infrared cables, where each of the infrared cables can have a respective first opening at a first end of the cable and a respective second opening at a second end of the infrared cable that is opposite the first end. The infrared cables can be configured to conduct infrared light emitted from a respective one of a plurality of monitored locations into the respective first opening to exit at the respective second opening. An infrared camera including an infrared sensor array can be optically coupled to each of the second openings of the plurality of infrared cables.

Various embodiments are directed to facilitating imagery and point-cloud based facility modeling and remote change detection. A computing device may receive collected data for a facility. The collected data may include spatial image data obtained from light detection imaging and ranging systems (LiDAR), multispectral data, and thermal data. The computing device may then analyze, based on software models generated for previously collected data for the facility, the collected data to determine changes in the previously collected data. The computing device may then update the models upon determining changes in the previously collected data. Finally, the computing device may generate an alert based on the updated models when any changes in the previously collected data are above a predetermined threshold corresponding to a current security or operational condition associated with the facility.
