ADT Monitoring Plans: What You Can Expect to Pay Monthly

ADT offers both professionally installed and DIY systems through its “Self Setup” plan. Here’s what you can expect in terms of monthly monitoring costs:

Equipment Costs: One-Time or Financed Over Time

Your monthly costs are only half the equation—ADT also requires an investment in hardware.

Note: Equipment can be customized with add-ons such as smoke detectors, carbon monoxide sensors, cameras, smart plugs, and more.

Installation: DIY or Professional?

ADT offers flexibility based on how hands-on you want to be:

• Professional Install: Required for traditional ADT packages. Typically, it costs between $99–$199 (may vary).
• Self Setup: No installation fee. You install it yourself, which is easy for most users.

Contract Terms & Hidden Costs

• Contract Length: 36-month minimum for professionally installed packages (24 months in California).
• Cancellation Fees: If you terminate early, you’re on the hook for up to 75% of the remaining balance.
• Activation Fees: Some packages include one-time activation costs.

Always read the fine print. ADT often runs promotions, but they still require a long-term commitment.
