One can compare medical alert systems on the basis of value, cost-effectiveness and quality. Purchase price, monthly fee, and alert neighbor facility are some of the features that can be taken into consideration.

It is a common practice for companies to compare their medical alert systems with those produced by other companies. Besides, companies provide comparison of their own products. Some of these alert systems come with warranty whereas some do not have one. Many of these products are endorsed by major medical foundations.

Some medical alert systems are specifically designed to cater to seniors living alone or left alone frequently, while others cater to both elderly people and those with certain medical conditions. Emergency medical response systems for babysitters and woodworkers are among the alert systems with maximum utility value. Watch type systems hide their alert buttons under the face of a water-resistant, fully-functional wristwatch. Some other alert systems resemble jewelry and can be worn on the wrist or around the neck. Yet others can be mounted on the wall for convenient access.

While most medical alert systems have console units, some alert systems have no console unit. One of the best examples for an alert system without console is the cell phone type alert system, which directly sends messages to the monitoring center. The alert systems with console unit work indoors or outdoors up to 100 feet from the console unit. Wireless alert systems have adjustable infrared sensors that transmit signals up to 1200 feet, and detect motion up to 30 feet away. Some medical alert systems inform the subscriber during dialing, shutdown, system test, and battery test.

To compare medical alert systems on the basis of battery life, the working time ranges from 18 to 24 hours without any power supply. Motion detector and fall sensor are additional equipments available with most medical alert devices.
