Systems and methods for determining status of sensors

A method comprising:

• receiving, by a computing device and from a sensor, a first message indicating a first measured strength of a magnetic field;
• setting, by the computing device and based on the first measured strength of the magnetic field, a threshold for detecting an alarm condition;
• determining, by the computing device and based on a plurality of messages, from the sensor, indicating a corresponding plurality of measured strengths of the magnetic field, a downward trend in a strength of the magnetic field;
• and
• sending, by the computing device and to a user device, and based on determining the downward trend in the strength of the magnetic field, a second message comprising:
• an indication of a potential problem associated with the sensor;
• and
• a request to modify the threshold.

A method comprising:

• determining, by a computing device and based on one or more first messages from a sensor indicating first measured strengths of a magnetic field, a reduction in a strength of the magnetic field;
• sending, by the computing device and to a user device, a request to modify an original threshold for detecting a security event;
• causing, by the computing device and based on determining the reduction in the strength of the magnetic field, setting of a modified threshold for detecting the security event, wherein the modified threshold is set to be lower than the original threshold;
• and
• determining, by the computing device, that the security event is not occurring based on a second message from the sensor indicating a second measured strength of the magnetic field that does not satisfy the original threshold and satisfies the modified threshold.
