Wi-Fi For Home Security
If you've resisted the siren's call to install your own wireless home network using Wi-Fi, the call is starting to get more difficult to resist all the time.

Sure, it's easy and it adds convenience for making broadband Internet access readily available all over your home. And when you have a notebook with a Wi-Fi card or with integrated Wi-Fi support, there's an ever-growing number of Wi-Fi hotspots that make remote Web access a snap.
D-Link's DCS-2100 wireless security camera

But if roaming around the house with a Web-ready untethered notebook isn't enough to get you interested in Wi-Fi, perhaps home or office security will. In the last few months the latest twist on the Wi-Fi phenomenon has been a combination of Web conferencing and security. Remember the Web cam? It's gone Wi-Fi, and it has a new security-oriented mission.

D-Link, the privately held home-networking concern, earlier this year announced the DCS-2100, which it's billing as a security camera. It connects directly to Wi-Fi networks anywhere the network's signal can reach, taking pictures that are easily viewable from a Web browser anywhere.

The camera shoots MPEG-4 video at a rate of 30 frames per second and includes an integrated Web server software package, an integrated microphone and a motion detection sensor. Video can be saved and archived directly to a hard drive, so you can watch what happens over time in your home or office. It also has an e-mail alert feature designed to send a snapshot of what the camera is seeing as an attachment to any e-mail address.

The camera sells for about $400 and is available from retailers, and works with PCs running Microsoft's (nasdaq: MSFT - news - people ) Windows. Another D-Link wireless camera, the $200 DCS-1000 also works with Apple Computer's (nasdaq: AAPL - news - people ) Macintosh platform. The package includes software that lets you manage as many as 16 cameras at once from a single PC. Just enough to turn your home or office into a high-surveillance location.
