Among my favorite consumer electronics devices are those that do hardly anything. Sometimes that’s all you need.

“Consumers no longer have to boot up their laptops in order to search for nearby Wireless Local Area Network (WLAN) service coverage, with the launch of IOGEAR’s new Wi-Fi Finder, a Wi-Fi location device. The easy-to-use product is a perfect tool for mobile workers, with a radio frequency range of 500 feet in open space. By clicking the ‘detect’ button, the device identifies nearby hotspots without interfering with 2.4GHz cordless telephones, A/V or Bluetooth devices. The Wi-Fi Finder also features four LEDs, which indicate WLAN coverage and signal strength.”

“The amazing Mini Bug Tracer RF detector is great for finding those hidden 2.4GHz wireless cameras. Outstanding performance in a small package. Keychain sized detector with telescopic antenna sniffs out hidden wireless cameras fast, assuring your privacy. Red light flashes faster as you get closer to the hidden camera. HI/LO buttons allow you to check out the entire room, then “home-in” on the bug.”
