• a processor;
• a non-transitory computer-readable storage medium comprising executable instructions;
• the executable instructions when executed by the processor cause the processor to perform operations comprising:
• detecting a lock tampering event raised by the sensor when a surface of the lock backplate is no longer in contact with the sensor indicating that the lock backplate was removed from the lock body;
• and
• reporting the lock tampering event when the safe is restored power after having lost power;
• wherein the sensor is anchored on an inside surface of the lock body proximate to the lock and includes a first end anchored to the lock body extending to a second end that makes surface contact with the lock backplate.
