How to Choose the Right Alarm System in NJ
After 41 years of installing alarm systems in New Jersey, here's our step-by-step recommendation process:
Assess Your Property
Count entry points (doors, windows, garage). Identify high-risk areas. Consider your NJ neighborhood's crime statistics. Most NJ homes need 6-12 sensors. Businesses typically need 10-30+ depending on size.
Choose Professional Monitoring
Professional monitoring is essential for emergency response and NJ insurance discounts. UL-Listed monitoring centers provide the fastest dispatch times. Self-monitoring saves money but does not qualify for most insurance discounts.
Plan for Integration
Will you add cameras, smart locks, or access control systems later? Choose a system that can grow with your needs without replacing equipment.
Compare Local NJ Companies
Get at least 3 quotes from NJ-licensed installers. Beware of low-ball equipment quotes with hidden monitoring fees. Ask about contract length, cancellation terms, and rate increase policies. Verify all licenses at NJ Division of Consumer Affairs.
Register Your Alarm Permit
After installation, register with your local NJ municipality. Most towns require registration within 30 days. Your alarm company should handle this for you, but verify it's done. Without registration, police may not respond to your alarms.
