Common Mistakes to Avoid

⚠️
Paying for professional installation when DIY is easy

Modern DIY security systems (SimpliSafe, Ring, Abode) are designed for easy self-installation. Save $200-$500 by installing yourself if you're comfortable with simple setup.

⚠️
Long-term monitoring contracts

Some professional security companies (Vivint, ADT) require 2-5 year monitoring contracts. Read the contract carefully; cancellation fees can be $500-$1,500. DIY systems offer month-to-month flexibility.

⚠️
Not checking for insurance discounts

Most homeowners insurers offer 5-20% discounts for monitored security systems. At $1,400/year insurance, a 15% discount saves $210/year - covering most of the monitoring cost.
