Smart Alarm Systems in 2026: What You Need to Know

The biggest shift in 2026 is the rise of no-contract, DIY systems that rival professionally installed options. SimpliSafe, Ring, and Cove offer systems you can set up in under 30 minutes with monitoring plans that do not lock you into multi-year contracts. Meanwhile, ADT and Vivint continue to lead in professional monitoring with faster response times and more comprehensive coverage.
