Hidden Costs to Budget For
These costs are rarely mentioned in initial quotes but can add hundreds annually:
Alarm Permits
$15-$50/yearRequired by most NJ and PA municipalities. Fees vary by township. Trenton: $20, Princeton: $35, Hamilton: $25. Must renew annually.
False Alarm Fines
$50-$250/incidentMost municipalities allow 2-3 false alarms per year before fines kick in. Each subsequent false alarm costs $50-$250. Proper installation reduces false alarms significantly.
Cellular Backup
$10-$20/monthIf you don't have a landline, cellular communication is required. Some providers include this; others charge separately. Always required for reliable monitoring.
Video Storage (Cloud)
$5-$30/monthCloud video storage costs vary by camera count and retention period. 7 days: $5- $10/month per camera. 30 days: $10-$20/month. Local NVR storage is a one-time cost ($300-$800).
Service Call Fees
$75-$150/visitNational chains often charge $100-$150 per service call. Local providers typically offer free or low-cost service calls ($0-$50) during business hours.
Contract Cancellation
$500-$1,500Many national providers lock you into 3-5 year contracts with steep cancellation fees. Read contracts carefully. Local providers often offer month-to-month or 1-year terms.
How to Save Money (Without Compromising Security)
Get Multiple Local Quotes
Save 15-30%Always get 3-5 quotes from local licensed contractors, not just national chains. Local providers often beat national pricing by 20-30% and offer better service.
Bundle Services
Save 10-20%Combining intrusion detection + video surveillance + access control often gets you 10-20% package discounts versus buying separately.
Start Essential, Expand Later
Save 25-40% upfrontCover critical entry points first (doors, ground-floor windows). Add cameras and additional sensors later when budget allows. Systems are designed for expansion.
Choose Wired Over Wireless (When Possible)
Save $200-500Wired sensors cost less than wireless and never need battery replacements. If you're renovating or have accessible attics/basements, wired is cheaper long-term.
Use Local Providers
Save $500-1,500/yearLocal companies avoid long-term contracts, reduce service call fees, and often include permits. This saves $40-125/month versus national chains.
Install During Off-Peak
Save 10-15%Security companies are busiest September-November and January-March. Installing during summer or late spring often gets you better pricing and faster scheduling.
Frequently Asked Questions
