security system service
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. Down theline, Yelamarthi wants to work toward integrating the Smart Cane's datawithGPS.

medical alert service
That’s all changed. Today you can buy DIY home security systems that have professional grade
wireless security equipment that’s extremely reliable, easy to install and affordable. Basic DIY home security systems start at about $225 and top out at $800 or so. If you add wireless smoke/heat detectors, plan to spend about $1,300 for DIY alarm systems. That’s about half of what a professional alarm company would charge. Monitoring service,
which notifies the police or fire department, can cost $40 or more per month. But if you shop around, you can get it for about $10 per month. Some alarm installers recommend eliminating window transmitters and installing motion sensors instead. These sensors are similar to the motion detectors that turn on outdoor floodlights. That approach can cut costs, but we don’t recommend it. Motion sensors cause the majority of false alarms.

how much do alarm systems cost
The cost of professional monitoring may range from $10/mo. up to $50/mo. Depending on the home
security plan and provider, you can opt for monitoring through cellular, broadband, or landline connection. When it comes to apps that control your home security system, you should determine your needs. If you have children who walk home from school, you’ll probably
want a video feature or arm/disarm alert that will let you know when they get home safe. If you like to check in on your pets, live security camera screening is something that will help you keep an eye on them.
