It appears the line between privacy and the use of technology to spy is becoming more and more blurred as gadgets become more advanced and cheaper.

Surveillance technology is no longer just being used for monitoring the security of properties, but also monitoring the lives of others.

A woman, who did not divulge her real identity, told ABC news that she used a $1,500 GPS tracking system to find out if her husband was having an affair.

"Spying could seem extreme [but] once you get to that point, you already know. It's more of a closure thing," she said. "I was blaming myself. I was turning into a state of depression. ... I know now that he's the jerk."

Stores that sell surveillance cameras say that in spite of tough economic times, their sales are still rising.

"Greed, lust and fear are the three high-growth industries and this covers all three," said  SpyAssociates.com owner Jeffrey Jurist, adding that his clients include law enforcement, individuals, private investigators and corporations. "Everybody's watching everybody. It's just a matter of whether you're aware of it."

"There's a fine line depending on how [it's being used] and who is using. It's up to the end user," he said, emphasizing that the law differs from state to state.
