A security system comprising:

• a plurality of sensors;
• and
• a base station that is configured to monitor the plurality of sensors, and to perform a method comprising:
• receiving an identification of a portable security system;
• adding the portable security system as a sensor to the plurality of sensors monitored by the base station;
• configuring, by the base station, the portable security system in protect-mode, wherein the portable security system sounds an alarm in response to a sensor from the portable security system indicating a security-breach;
• and
• in response to the alarm from the portable security system, generating, by the base station, an alarm event of the security system.

A portable security system comprising:

• a sensor;
• and
• a processor configured to perform a method to secure an item by expanding a central security system, the method comprising:
• sending a request to a base station of the central security system to add the portable security system as a sensor of the central security system, the request comprising an identification code that identifies the portable security system;
• receiving, in response, from the base station, a confirmation indicating that the portable security system has been added to a list of sensors of the central security system;
• transitioning the portable security system in protect-mode, in response to receiving an instruction from the base station, wherein the portable security system generates an alarm in response to the sensor indicating a security-breach;
• and
• in response to the security-breach, sending, by the portable security system, a notification to the base station to generate an alarm event of the central security system.
