*Pricing above reflects monitoring rates only. Upfront equipment and installation costs vary depending on whether we are taking over an existing compatible system or installing a new system. Please refer to the System Builder or contact us for an exact upfront quote.

Afterpay Available

Protect Now. Pay Later.

We believe everyone deserves top-tier security. If paying for equipment upfront isn't an option, we offer Afterpay as a transparent alternative to predatory in-house alarm financing.

  • Pay in 4: Split your equipment cost into four interest-free installments. (Soft credit check, no impact on credit score)
  • Pay Monthly: Spread costs over 6 to 12 months for larger systems. (Hard credit check may apply)
  • No In-House Debt Traps: We keep monitoring costs low by never financing equipment ourselves. You own it from day one.

How it works

  1. Build your custom system and submit your quote.
  2. When we send your final invoice via Square, select the Pay Later / Afterpay option at checkout.
  3. Get approved instantly and complete your purchase.
  4. We ship and activate your system immediately!
Disclaimer: Afterpay is a third-party service. Defaulting on payments may affect your credit. Defendr Security is not responsible for the equipment transaction after purchase; we are only responsible for providing your monitoring service.

Keep Your Current System

Don't want to replace everything? You don't have to. We specialize in compatible system takeovers.

  • Avoid unnecessary replacement costs
  • Lower-cost path into professional monitoring
  • App access available on qualifying systems
  • Great for customers leaving other providers
Check Compatibility

Disclaimer: We cannot takeover ADT, Vivint, SimpliSafe, Nest, Ring, or 3rd Party Alarm Systems from China because they either use proprietary systems designed to lock customers into being forever customers, or the equipment from China does not have the necessary communicators that are UL compliant.

Frequently Asked Questions

Everything you need to know about our services, contracts, and equipment.

No, we do not require credit checks for our monitoring services. We believe everyone deserves security without unnecessary financial hurdles. If you choose to finance equipment through Afterpay, they may perform a soft credit check that does not impact your score.

We offer true freedom from traditional binding contracts. If you pay for your equipment upfront, you are not locked into a long-term contract. We offer Month-to-Month options, as well as discounted 12-Month and 36-Month agreements for those who prefer lower monthly rates.

To keep our monitoring rates as low as possible, we do not offer in-house financing. However, we do accept Square Pay Later and Afterpay, which allow you to split your equipment cost into manageable payments.

Yes! We offer "Bring-Your-Own System" takeover plans starting at just $19.99/month. Our expert technicians can typically reprogram your existing equipment to connect with our professional monitoring center, saving you the cost of buying a new system.
