Determining sensor installation characteristics from camera image

A system comprising:

• a processor;
• and
• a memory in communication with the processor, wherein the memory stores instructions that, when executed by the processor, cause the processor to:
• receive an image of at least a portion of a room, the image of the room comprising an image of a sensor mounted in the room;
• receive at least one optical parameter related to the image of the room;
• determine a distance between the sensor and a camera that captured the image of the room, wherein the determination of the distance is based at least in part on the image of the room, on the optical parameters, and on known physical dimensions of the sensor;
• determine a sensitivity requirement of the sensor, based on the distance;
• send the determined sensitivity requirement to control logic of the sensor;
• configure the sensor to operate at the determined sensitivity requirement to determine an alarm event.
