Families on vacation can use camera phones like instant postcards to send back to loved ones. Insurance adjusters and realtors can use them for business.

	Some phones can record short amounts of video

Along with better technology sometimes comes worse behavior. Cellular phones with attachable cameras or cameras built inside are becoming more popular, but some worry they could also cause more problems.

AT&T sells phones that not only record still photos, but also record up to 15 seconds of video with sound. It's like carrying a miniature video camera right in your pocket.

But the innovation concerns managers at some Central Texas music venues like The Backyard. Before folks can get in to see concerts, like David Gray who performed at The Backyard Monday night, must go through security, and cameras are not allowed.

But with more people carrying cell phones, and possibly cameras built inside, it creates an interesting dilemma for many places where cameras are banned.

"You know the bands -- their names, their music, their image -- everything is licensed. And if somebody takes a photograph of the band, and that picture ends up on e-bay and somebody's paying money for it, the band's not seeing any of that revenue, then they have a problem with it," Barry Kohlus, with The Backyard, said.

	Phones may become a security issue

There are also concerns in Tokyo where the technology is everywhere. There are reports of people there secretly taking photos of women at gyms and in bathrooms.

"These camera phones are really part of a trend," David Phillips, University of Texas asst. professor, said.

Phillips said it may be alarming, but he believes people should be more worried about corporate surveillance, rather than cell phone snooping.

"Purchasing habits, their travel habits, their Web habits, the way that kind of behavior, which is public behavior, used by organizations. Its that kind of surveillance of public activity that concerns me far more," he said.

Although the cameras have been known to incite some bad behavior, they can also prevent criminal acts.

Last week a 15-year-old in Clifton, N.J. used his phone cam to snap a shot of a would-be kidnapper.

"He actually took a picture of a crime in progress. He also took a picture of the car and including the plate number," Capt. Robert Rowan, of the Clifton Police Department, said.

Police used the phone to make an arrest.

	Camera phones Advancing technology in cell phone cameras may make them a security issue in the near future.

"Camera phones here in the U.S. are getting a little bit of a later start, but certainly we're starting to see the demand pick up, especially in Austin, which is so tech savvy," Jason Cardwell, an AT&T Wireless market director, said.

Managers at The Backyard said the issue of camera phones has come up in previous meetings before. They said so far no artists have complained about them.

But, in the future as the camera phone pictures get even clearer, they say they'll have to explore the issue further.
