The present invention relates to a security system for personal protection, having a first unit and a second unit separate from the first unit, wherein the first unit has a camera device, a microphone device, a siren device, a safety device, an attachment device, and a communication device for communication wirelessly with the second unit. The second unit has a microphone device and a communication device for communication wirelessly with the first unit. The second unit further has a communication device for wirelessly sending an alarm message to a network of one or more recipients. The security system is configured to, when triggered to send an alarm message, activate the microphone device of the first unit and the microphone device of the second unit, such that the alarm message contains an audio recording from an environment of a user of the security system. A method and a security arrangement therefore are also presented.
