We interrupt this program for a commercial message ... Nanny-Cam May Leave a Home Exposed Nanny-Cam May Leave a Home Exposed Sat Apr 13, 2:55 PM ET By JOHN SCHWARTZ The New York Times Thousands of people who have installed a popular wireless video camera, intending to increase the security of their homes and offices, have instead unknowingly opened a window on their activities to anyone equipped with a cheap receiver. The wireless video camera, which is heavily advertised on the Internet, is intended to send its video signal to a nearby base station, allowing it to be viewed on a computer or a television. But its signal can be intercepted from more than a quarter-mile away by off-the-shelf electronic equipment costing less than $250. A recent drive around the New Jersey suburbs with two security experts underscored the ease with which a digital eavesdropper can peek into homes where the cameras are put to use as video baby monitors and inexpensive security cameras. The rangy young driver pulled his truck around a corner in the well-to-do suburban town of Chatham and stopped in front of an unpretentious home. A window on his laptop's screen that had been flickering suddenly showed a crisp black-and-white video image: a living room, seen from somewhere near the floor. Baby toys were strewn across the floor, and a woman sat on a couch. After showing the nanny-cam images, the man, a privacy advocate who asked that his name not be used, drove on, scanning other homes and finding a view from above a back door and of an empty crib. In the nearby town of Madison, from the parking lot of a Staples store, workers could be observed behind the cash register. The driver walked into the Staples and pointed up at a corner of the room. "Take a look," he said. Above the folded-back steel security shutters was a nubbin of technology: a barely perceptible video camera looking down on the employees. "I can only imagine driving around the Bay Area with one of these," said Aviel D. Rubin, a security researcher at AT&T Labs who was along for the ride. ... <http://www.securityprousa.com/nanmayleavho.html> ... and now back to our regularly scheduled program. ...

However, there is software that will allow for auto-blurring faces and key elements in the video as it's fed back out from the storage, but keep the original input feed entirely clear.There are a number of issues that you need to consider before going through with this type of project. Some of the following is from my experience of dealing with video surveillance vendors after the APril 2007 incident here. 1. FERPA - relates to the privacy comment above. I'm sure you have some students who have a "privacy" tag on their records for whatever reason. Not having a sign informing everyone that they are under surveillance may cause problems if their desire to remain private/anonymous is for safety reasons (stalker, parent with a restraining order against them, etc.). I believe it's prudent to inform the occupants that they may be under surveillance. Some people don't care, some do. I'm not saying you can't film public areas but from a PR standpoint, informing them addresses a lot of issues. 2. Any video camera system must restrict who can access its images. See webcam.prejeans/com/view/index/shtml and ask yourself if you really want the entire internet to see these images. 3. Any video camera system must encrypt the video feed from the cameras to whatever server. Again, should there be an incident, you don't want a video of the crime to be on YouTube or CNN. Having the video cams on a physically separate network isn't secure. This is an issue if you're looking at wireless camera systems. Wireless is radio and signals can be intercepted and replayed.
