Abstract
Methods and systems for security event detection are disclosed. A device may determine that it is not receiving power from a power line circuit located external to the device. The device may comprise at least one contact configured to connect to the power line circuit. Based on applying a first signal via the at least one contact, a reactance associated with the at least one contact may be determined. A cause for the device not receiving power from the power line circuit may be determined based on the reactance.
Claims20
A method comprising:
- determining, by a device comprising at least one contact configured to connect to a power line circuit located external to the device, that the device is not receiving power from the power line circuit;
- determining, based on applying a first signal via the at least one contact, a reactance associated with the at least one contact;
- and
- determining, based on the reactance, a cause for the device not receiving power from the power line circuit.

A method comprising:
- determining, by a device comprising at least one contact configured to connect to a power line circuit located external to the device, that the device has stopped receiving power from the power line circuit;
- determining a reactance via the at least one contact;
- determining, based on the reactance failing to satisfy a threshold, that a security event caused the device to stop receiving power from the power line circuit;
- and
- sending, to at least one computing device, a notification indicative of the security event.

A method comprising:
- determining, by a device comprising at least one contact configured to connect to a power line circuit located external to the device, that the device has stopped receiving power from the power line circuit;
- determining a reactance via the at least one contact;
- and
- determining, based on the reactance satisfying a threshold, that a power outage associated with the power line circuit caused the device to stop receiving power from the power line circuit.
