The personal security system transmits a picture of an object, such as a criminal suspect, and the identification of a portable transmitter, such as the social security number of the user, to a receiver at a remote location. Time of transmission is recorded. If a crime occurs, the time, picture of the suspect, and identification of the victim are obtained from a recorder at the receiver. A potential victim of a crime points his portable personal security unit at a criminal suspect and presses an activating switch. The unit senses available light on the object and provides a flash if required. At the same time focusing an aperture control is performed and an image of the object is admitted to an image recorder which is a focal plane sensor array. Image data from the focal plane sensor array is processed in an image data processor and the processed image data is fed to a cellular communication transmitter for transmitting to the remote receiving station. An audio pickup at the portable unit is connected to the receiver for transmitting voice communications over the transmitter. By pointing the device at a suspect and pressing a button, a person makes a permanent record of an image.
