Spy cam and GPS devices are often promoted by the companies that sell them as a convenient way to catch a cheating spouse.
But experts in domestic violence say these devices are making it easier for perpetrators of family violence to stalk and keep track of partners and ex partners and victims fear they are being constantly watched or monitored.
Research has found that with technology breaking down traditional geographical barriers, perpetrators can contact women from a distance at any time and some victims have been harassed with hundreds of text messages a day.
The use of technology is causing a rise in the number of breaches of intervention orders as the courts try to keep up with the numerous ways new devices are being used to stalk people.
