Low power gunshot detection

An apparatus for gunshot analysis comprising:

• a mid-infrared (MIR) band sensor located in a housing, wherein the mid-infrared band sensor provides motion detection;
• a near-infrared (NIR) band sensor co-located in the housing, wherein the near-infrared band sensor initiates buffering of NIR information, based on the mid-infrared band sensor detecting motion;
• an acoustic sensor co-located in the housing, wherein the acoustic sensor collects high-intensity sounds and enables acoustic monitoring;
• and
• a battery, wherein the battery is connected to provide power to the sensors, and wherein the battery is contained within, on, or next to the housing.

A computer system for gunshot analysis comprising:

• a memory which stores instructions;
• one or more processors coupled to the memory wherein the one or more processors, when executing the instructions which are stored, are configured to:
• collect infrared information using a gunshot sensor device, wherein the infrared information is collected using mid-infrared (MIR) band sensing to provide motion detection;
• buffer additional infrared information using the gunshot sensor device, wherein the additional infrared information is collected using near-infrared (NIR) band sensing, and wherein the buffering is enabled by the motion detection;
• collect acoustic information using the gunshot sensor device, wherein the collecting acoustic information is enabled by the motion detection;
• and
• detect a gunshot using the gunshot sensor device, wherein the detecting is based on the additional infrared information and the acoustic information.
