That means you don’t have to break, drill, fish, or run wires through your wall, and you could connect to your control box without having costly electrical installations. The larger the house, the bigger is the savings when it comes to wireless configurations. However, if your home is too large, you might need to go for hard wired to be able to have a more reliable security system. In general, a 2GHz system can keep constant connection with wireless components in about an acre worth of residential area. One disadvantage of the wireless system is that the components will eventually run out of battery life. It is therefore necessary to invest in a dependable battery backup system not only in case of emptying battery life but also to continue to protect your home even in the event of a power outage or a break in attempt by an intruder. Also, note that it is better to buy equipment that is powered by rechargeable batteries. They may have a larger upfront cost, but will prove to be more economical in the long run. Look for a system that notifies you or gives an alarm that can alert you if which batteries are running low. Or if you can, frequently test the components of your system and replace batteries regularly. Another disadvantage of a wireless configuration is the risk of faulty installation.

An engineering professor and five students at Central Michigan Universityhave created a ''Smart Cane'' to read electronic navigational tagsinstalledbetween buildings to aid the blind in reaching their destinations moreeasily. ''This project started as a way for me to teach students to see andunderstand the ways that engineering can be used for the greater good,''said Kumar Yelamarthi, the professor and project leader. ''We wanted to dosomething that would help people and make our campus more accessible. '' During the spring term, Yelamarthi and five senior engineering studentstested the cane, which is equipped with Radio Frequency Identificationtechnology, similar to what retailers put on products to keep them frombeing stolen. The Smart Cane contains an ultrasonic sensor that is paired with aminiaturenavigational system inside a messenger style bag worn across the shoulder. For the test, the students installed identification tags between twobuildings on the campus in Mount Pleasant, Mich. A speaker located on thebag strap gave audio alerts when the system detected an obstacle and toldthe user which direction to move. Students wearing glasses that simulate visual impairment tested the cane. The students also created a vibrating glove to assist those who are bothvisually and hearing impaired. Yelamarthi said it's one of the first outdoor applications of RFID and saidhe plans for students in upcoming classes to further refine the systemwhilehe seeks grants to speed the research. The next step probably involves using the system in a wider area.
