Frequently Asked Questions
How much does a home security system cost in New Jersey?
In New Jersey, a complete home security system typically costs $500-$2,500 for equipment and installation, plus $25-$60/month for professional monitoring. Basic systems start around $200-$500 for equipment only. Professional installation adds $100-$500 depending on system complexity. Costs vary by county—Mercer County and Bucks County PA have similar pricing due to comparable labor rates.
Is professional monitoring worth the monthly cost?
Yes, professional monitoring ($25-$60/month) is worth it for most homeowners. Benefits include: 24/7 trained operators who dispatch emergency services even when you're unavailable, 10-20% homeowner's insurance discounts that often offset the monitoring cost, and fire/CO monitoring that can save lives. Self-monitoring (free) only sends alerts to your phone—you must call 911 yourself.
What is included in a typical home security system?
A typical home security system includes: control panel ($100-$300), 8-12 door/window sensors ($15-$30 each), 2-4 motion detectors ($30-$50 each), 1-2 glass break sensors ($40-$60 each), keypad or touchscreen ($50-$200), siren ($30-$100), and cellular communicator for monitoring ($50-$150). Cameras, smart locks, and video doorbells are optional add-ons.
Are there hidden fees with home security systems?
Common hidden fees to watch for: activation fees ($50-$200), permit fees ($25-$100 depending on NJ/PA municipality), early termination fees (remaining contract balance), equipment upgrade fees, and service call fees ($50-$150 for non-warranty visits). Reputable local companies like Security Dynamics disclose all fees upfront and offer month-to-month monitoring options.
DIY vs professional installation: which is cheaper?
DIY systems are cheaper upfront ($200-$500 for equipment) but may cost more long-term due to: no professional system design (gaps in coverage), no warranty on installation, potential permit issues, and limited integration options. Professional installation ($100-$500) includes proper sensor placement, system testing, permit handling, and training. For homes over 2,000 sq ft or with complex layouts, professional installation typically provides better value.
