Gadgets: Affordable security cameras

$300 & up • www.logitech.com

Logitech has a line of new home-monitoring webcams, available in September, that are easy to set up and deliver high-resolution video for a consumer-level camera. The cameras come in two versions -- the $300 Alert 750i Master System for indoor use and the weatherproof $350 Alert 750e Outdoor Master System. Once the "master" camera is installed, up to five more cameras can be installed at a cost of $230 each for indoor and $280 each for outdoor models.

Each camera comes with its own networking kit, which uses existing electrical wiring and outlets to connect the camera to a home network. They require broadband Internet.

The cameras capture video at a resolution of 960 by 720 pixels at a maximum 15 frames a second.

They have motion sensors and dispatch an e-mail alert when they detect activity. The live video, but not recorded events, can be viewed via a secure, and free, website. The cameras also have a built-in microphone.

Setup is a simple three-step process. After installation, the camera records video to an included two-gigabyte MicroSD memory card when it senses motion.

The recorded video is automatically backed up to the PC connected to the network.

TWO POWER PACKS FOR IPHONES

$30-$40 • www.mophie.comwww.konnetonline.com

Mophie, maker of the $40 Juice Pack Reserve, a new battery charger for an iPhone, says its external battery is so small (it is roughly the size of a Zippo cigarette lighter) that you could carry it on your belt. To help you do that, the package includes a carabiner clip. Three LED lights illuminate to tell you when it is fully charged. And when you are not using it to charge your iPhone, it functions as a small LED flashlight.

Another new charger is the PowerEZ Plus, from Konnet, which sells for $30. Its small pull-out frame props the phone into the landscape position, so you can keep watching a movie or playing a game while you recharge your battery.

Both products use 1,000 mAh lithium polymer batteries and protect against overcharging. The PowerEZ Plus requires you to push the activation button before it begins charging, a fact that the company inconveniently forgot to note on its packaging.

Still, when connected, these new chargers hang below the iPhone, meaning that an inadvertent knock could dislodge them. And so some people may prefer the older $60 JumpStart Attachable Battery Pack from Philips. This external battery wraps around the iPhone and adheres to it with mini-suction cups. It doubles the thickness of the center of the phone, but it remains unobtrusive, and feels good to the touch.
