Editors Recommendation

Generally, we recommend ADT over Life Alert due to their lower monthly monitoring cost and optional fall detection. ADT uses top-notch equipment utilized by several other highly rated medical alert companies. Both ADT and Life Alert offer installation for an additional fee. However, if you need a longer battery life on the mobile unit, Life Alert boasts the longest battery life in the industry.

Life Alert and ADT Medical Alert are industry leaders when it comes to medical alert systems. Both are well-known for their state of the art devices and the technology they use to maintain emergency connectivity. While Life Alert requires a 3-year contract, ADT Medical Alert tends to be more user-friendly offering month-to-month payment options and discounts for AARP members and ADT customers who already have the home security system installed in their home.

Life Alert and ADT Medical Alert are different in many areas, especially in terms of contracts, installation, and how the systems operate. Life Alert requires professional installation while ADT allows their subscribers to choose whether they want to install the system themselves or have a professional technician visit their home. Another important difference is in the range of their devices. ADT Medical Alert has a range of less than 600 feet. Life Alert, on the other hand, has a range of over 800 feet.
