Short answer
In New Jersey a home security system runs from a few hundred dollars for a basic starter setup to several thousand for a larger property, plus a monthly monitoring fee. The price moves with the size of the property, the number of sensors and cameras, professional installation, and local permit and false-alarm fees.

The cost of a home security system in New Jersey varies widely depending on the size of your property, the equipment you choose, and whether you use professional monitoring. A basic starter system might run a few hundred dollars, while a comprehensive setup for a larger property can reach several thousand — plus ongoing monthly fees.
This guide breaks everything down so you can plan with general estimates and know what to ask for in an itemized quote.
What Affects the Cost?
Three main factors determine what you'll pay:
- Equipment — the sensors, cameras, control panel, and smart devices you install
- Installation — labor costs for professional setup and wiring
- Monthly monitoring — the recurring fee for 24/7 professional oversight
Each varies significantly based on your property size, the level of protection you need, and the company you hire.
Equipment Costs
The ranges below are general market estimates as of 2026 for equipment only: the panel, sensors, cameras and accessories, without labor or monitoring, which are covered separately below. They are not installed prices and not a BGS Security quote; your actual price depends on the property and the equipment chosen.
Entry-Level Systems (equipment: $400–$900)
Entry-level systems typically include a central control panel, a handful of door and window sensors, one or two indoor cameras, and a basic siren. These are adequate for small apartments or starter homes but fall short for larger or more complex properties.
Mid-Range Systems (equipment: $900–$3,000)
Mid-range installations cover a complete perimeter — all entry points, motion detectors in main living areas, several outdoor cameras, and a smart panel with app access. This is the range most single-family homes fall into.
Comprehensive Systems for Larger Properties (equipment: $3,000–$10,000+)
Larger estates require proportionally more coverage: full perimeter cameras, access control at gates and doors, video intercoms, glass-break sensors, environmental detectors (smoke, CO, flood, freeze), and integration with existing smart home systems. For properties with extensive grounds, guesthouses, or multiple structures, costs can exceed $10,000 in equipment alone.
Professional Installation Costs
DIY installation is an option with some consumer-grade systems, but professional installation is recommended — especially for hardwired equipment, camera placement that requires runs through walls, and integration with home automation platforms.
General estimates for installation labor in NJ (2026, labor only, not a BGS quote):
- Standard residential installation: $200–$600
- Multi-camera system with structured wiring: $600–$1,500
- Full estate with access control and intercom: $1,500–$3,500+
BGS Security includes professional installation in an itemized written quote, so labor is set out before you sign.
Monthly Monitoring Fees
Professional monitoring connects your system to a central station staffed 24 hours a day, 7 days a week. When an alarm triggers, operators follow the procedure agreed for the property, which typically includes verifying the event before requesting police, fire, or medical services.
General market estimates for monitoring (2026, all providers, not a BGS quote):
- Self-monitored (app alerts only): $0–$10/month
- Basic professional monitoring: $20–$35/month
- Professional monitoring with cellular backup: $35–$55/month
Cellular communication matters. A system that relies solely on broadband cannot report while the internet connection is down. Battery and cellular backup help maintain monitoring within the system's supported limits, for example through an internet outage or, for as long as the battery lasts, a power outage.
BGS Security professional monitoring starts at $29.99/month, month-to-month with no long-term contract; the alarm monitoring page lists what the plan includes. Equipment and installation are quoted separately after the property assessment.
Permit and False Alarm Fees in New Jersey
Many New Jersey municipalities require an alarm permit or registration; whether there is a fee, how much it is and whether it renews annually is set by each town. Many towns also impose false alarm fines after a set number of accidental dispatches per year, with amounts that rise on repeat incidents.
Professional design and testing help reduce false alarms. Sensors placed and configured for the home's layout, pets and heating system are less prone to accidental triggers than ones mounted wherever was convenient.
Where a permit is required, it is registered with the local police department or municipal clerk in the homeowner's name. BGS Security researches the local requirements for each installation and handles the registration process on your behalf.
What's Often Left Out of Quotes
Watch for these line items that some providers don't mention upfront:
- Activation fees: Some companies charge a one-time fee to activate monitoring service.
- Equipment buyout clauses: Certain providers own the equipment and require you to return it or buy it out when you cancel.
- Price escalation clauses: Multi-year contracts often include annual rate increases baked into the fine print.
- Service call fees: If equipment fails outside of warranty, some providers charge for technician visits.
Ask any security company to provide a fully itemized quote before you sign anything.
Is a Premium System Worth the Investment?
For larger homes and businesses it often is. Larger properties are more complex to protect, and professional-grade equipment can offer better supervision, image quality, and service life, depending on the model and setup.
A professionally monitored system may also qualify for a homeowners insurance discount. Ask your insurer whether your system qualifies and what documentation is required.
