High-tech eavesdropping

A wireless (cellular) phone can be used as a listening device. Depending on the phone's settings, it can silently pick up sounds within its proximity. A batterer can strategically place a wireless phone in a home, car, or on someone's person and call the number throughout the day to hear conversations and activities. The phone never rings, but automatically answers. If the victim is not aware of these features, she will never know that her communication is monitored. Certain models of corded fax and answering machines also offer this feature, although the ringing action is usually more obvious.

Batterers may be particularly capable of monitoring the communication of a partner with a physical disability. Certain visual impairments may require a person to use large print or a software program that reads aloud text from the computer screen.
