Alder offers tailored equipment and monitoring packages for its clients. As the price differs depending on the equipment you choose, Alder cannot share the price of its service online, but you can work with a specialist over the phone to get a quote. ADT, on the other hand, is transparent with its prices. It offers professional monitoring starting at $45.99/mo., with $599 of equipment to be paid over the course of your contract.

While Alder offers its clients a 30-Day Money-Back Guarantee, ADT wins this round. With its 6-Month Money-Back Guarantee for customers to try their service and equipment risk-free. Since ADT offers a longer trial period they win this round.

As Alder does not give a quote for its equipment online, it is difficult to compare equipment prices. However, when it comes to their selection of devices, both companies offer a comprehensive range of equipment, including a digital panel, security cameras and motion sensors. Both Alder and ADT have mobile apps that allow you to arm and disarm your alarm. However, ADT offers smart locks, video doorbells and more for smart home security – making them the winner of this category.

Alder wins this category by a hair. Both Alder and ADT offer their clients 24/7 professional monitoring through a cellular connection so that your home is protected all the time. Alder gets the edge, though, with its month-to-month service plan, while ADT requires a minimum 12-month monitoring contract.

ADT wins this round hands down. If your home is broken into while your ADT system is armed they’ll pay up to $500 of your insurance deductible. ADT also offers an extended limited warranty for any installed equipment to cover repairs and replacements if needed. Lastly, ADT offers a 6-Month Money-Back Guarantee to refund all costs if there’s a system or service issue they cannot resolve. On the other hand, Alder offers only a 30-Day Money-Back Guarantee.

When it comes to installing security systems, Alder offers more flexibility. ADT only offers a professional installation option. Professional installation and equipment will set you back an average of $99. Alder, on the other hand, only offers a DIY installation option, making it more suitable for renters.
