    PROS / This company's base station units include a temperature monitoring sensor, which can detect unusual high or low temperatures.

    CONS / The Medical Alert Basic station has the lowest advertised emergency battery life in its base station.

    VERDICT / Backed by a leading company in home security, ADT's medical alert systems offer decent ranges to cover many homes.

    ADT is a leading name in home security, and it offers a basic medical alert system and service. The company includes a 24/7 medical monitoring service, a standard feature for all comparable medical alert systems. This type of service means that you or your family member using the system can call and get help from a live representative at any time, even at night or during holidays.


    ADT offers two alert systems you can choose from, based on the range you need and the hardware you prefer. The Medical Alert Basic unit is their standard unit with an optimal 300-foot range, which is on the low end for comparable medical alert systems. The range should cover most small homes, but it varies based on the material your house is built from and how many rooms and walls there are.

    This unit requires a landline in order to send out calls to the ADT monitoring centers. In the event of an emergency where you use the button, the base station will take control of your phone line to send the call. Any of ADT's base stations can detect temperatures in case of a fire or other temperature-based emergency that can result in problems.

    If you need a larger range, the company offers a package upgrade, the Medical Alert Plus. You don't need a landline in order to use this unit, so this is a great option for households without a landline. This unit also includes an optional fall-detection pendant, which can detect most falls and automatically send for help in case you can't.

    Both systems automatically check themselves for any issues; if there are hardware problems, the units will send an alert to the monitoring center, which will then contact you to help troubleshoot the system. The emergency pendants are waterproof, so you can wear them during a shower in the bathroom, where there is a high risk of slipping and falling.


    ADT's medical alert systems have an average range for its base station and emergency alert pendant. The company includes the standard 24/7 monitoring, so you or your loved one can get help at any time of the day.
