A home security system is a network of devices — sensors, cameras, alarms, and a control hub — that detects unauthorized entry, fire, or environmental hazards and triggers an alert or notifies a monitoring center. BGS Security has designed and installed these systems across New Jersey for over 30 years, and this guide reflects what we’ve learned from thousands of real installations.
What is a home security system and how does it work?
A home security system works by connecting sensors placed at entry points and throughout the home to a central control hub. When a sensor is triggered — a door opened, motion detected, glass broken — the hub evaluates the signal and either sounds a local alarm, sends a notification to the homeowner’s phone, or contacts a professional 24/7 monitoring center that dispatches emergency services.
The core components of a modern home security system are:
- Control hub / panel — the brain of the system; processes all sensor signals
- Door and window sensors — detect opening or forced entry
- Motion detectors — identify movement within defined zones
- Security cameras — record or stream video of the property
- Siren / alarm — audible deterrent and alert
- Keypad or smart app — used to arm, disarm, and configure the system
- Monitoring connection — cellular, Wi-Fi, or both, connecting to a monitoring center
Modern wireless systems like those based on the AJAX platform communicate over encrypted radio frequencies, making them resistant to jamming and interference — a meaningful upgrade over older wired systems.
What are the different types of home security systems?
There are four main types of home security systems, distinguished by how they communicate and whether they include professional monitoring.
1. Professionally monitored systems
The system is connected to a 24/7 monitoring center. When an alarm is triggered, trained operators verify the event and dispatch police, fire, or medical services as needed — regardless of whether the homeowner is available. This is the standard BGS Security installs for New Jersey homes. Read more: Alarm Monitoring →
2. Self-monitored systems
Alerts go directly to the homeowner’s smartphone. There is no third-party response — the homeowner must assess the situation and call for help themselves. This creates a gap in protection when the phone is unavailable, in a meeting, or the homeowner is traveling.
3. Wired systems
Sensors are hardwired to the control panel. Highly reliable and tamper-resistant, but installation is invasive and better suited to new construction or full renovations.
4. Wireless systems
Sensors communicate via encrypted radio frequency or Wi-Fi. Installation is non-invasive, the system is portable, and it can be expanded at any time by adding sensors or devices. The AJAX wireless system — the platform BGS uses — includes cellular backup, so the system stays active even if the internet connection is cut.
What components does a home security system include?
A complete home security system for a New Jersey single-family home typically includes the following components:
| Component | Function |
|---|---|
| Control hub (e.g., AJAX Hub 2 Plus) | Central processor; communicates with all devices and the monitoring center |
| Door/window sensors (e.g., AJAX DoorProtect) | Trigger alarm if entry point is opened while armed |
| Motion detectors (e.g., AJAX MotionProtect) | Detect movement in interior zones |
| Outdoor motion detectors (e.g., AJAX MotionProtect Outdoor) | Perimeter protection; weather-resistant |
| Security cameras | Visual verification and evidence |
| Glass break detector (e.g., AJAX GlassProtect) | Detects frequency of breaking glass |
| Smoke / fire detector (e.g., AJAX FireProtect 2) | Early fire warning; connects to monitoring center |
| CO detector | Carbon monoxide detection |
| Siren (indoor + outdoor) | Audible deterrent |
| Keypad or app | Arm/disarm and system control |
The exact configuration depends on home size, number of entry points, and the level of protection required. BGS Security provides a free assessment for New Jersey homeowners to determine the right setup. Schedule a consultation →
What is the difference between monitored and unmonitored security systems?
A monitored security system is connected to a professional response center that acts on your behalf when an alarm is triggered. An unmonitored system relies on a loud alarm and notifications to the homeowner — no backup response exists if the homeowner cannot act.
The practical difference: if a break-in occurs while you are asleep, traveling, or your phone is off, a monitored system will dispatch police regardless. An unmonitored system will sound a siren and send a push notification. If no one acts on that notification, no help is coming.
Professional monitoring from BGS Security operates 24/7 via cellular connection, so it remains active even during power outages or if the internet is cut. Learn how alarm monitoring works →
What is the difference between wired and wireless home security systems?
Wired systems use physical cables to connect sensors to the control panel. They are highly reliable because there is no radio frequency to jam, but installation requires routing cables through walls — practical only during construction or major renovation.
Wireless systems use encrypted radio or Wi-Fi signals between sensors and the hub. Installation is non-invasive, the system can be moved or expanded easily, and battery-powered sensors continue to work during power outages. AJAX wireless devices use a proprietary radio protocol (Jeweller) with two-way communication and anti-jamming detection — if interference is detected, the hub immediately reports it.
For most New Jersey homes, wireless is the practical choice. For new construction projects, a hybrid approach (wired backbone, wireless sensors) is worth considering.
How much does a home security system cost in New Jersey?
The cost of a home security system in New Jersey depends on three variables: equipment, installation, and ongoing monitoring.
Equipment:
- Entry-level system (hub + 4–6 sensors): $400–$700
- Mid-range system (hub, sensors, cameras, siren): $700–$1,500
- Full-coverage system (hub, comprehensive sensors, indoor and outdoor cameras, environmental detectors): $1,500–$3,000+
Installation:
- Professional installation by BGS Security: included or quoted separately depending on system size
- DIY installation: applicable for some wireless systems, though professional placement maximizes effectiveness
Monitoring:
- Professional 24/7 monitoring: starting from the plans listed on BGS pricing →
- Self-monitoring: no monthly fee, but no professional response
Insurance savings: Most New Jersey homeowners insurance providers offer a 5–15% discount on premiums for homes with a professionally monitored alarm system. Over several years, this discount meaningfully offsets the cost of monitoring.
What should I look for when choosing a home security system?
When evaluating home security systems, the most important factors are:
1. Monitoring reliability
Does the system use cellular backup, or is it internet-only? An internet-only connection is vulnerable to outages and router unplugging. BGS systems use AJAX, which includes dual-path communication.
2. Sensor coverage
Does the system cover all entry points — doors, windows, garage? Are outdoor zones included? Are environmental hazards (fire, CO, water) addressed?
3. Response time
How quickly does the monitoring center contact you and dispatch emergency services? Ask for documented response time standards.
4. System expandability
Can you add cameras, sensors, or smart devices later without replacing the core system?
5. Local installation and support
A local installer who knows New Jersey can conduct a real security assessment of your property — not just ship a kit. BGS Security provides in-person assessments at no charge. Contact us →
Should I install a home security system myself or hire a professional?
DIY installation works well for renters or those with simple, small-footprint needs. Most wireless systems are designed for self-installation — a hub, a few sensors, a phone app.
Professional installation is the right choice when:
- The home has multiple floors, outbuildings, or a large perimeter
- You want cameras placed for optimal coverage (not just convenient coverage)
- Integration with fire and CO monitoring is required
- You want a system that will be serviced and maintained over time
The most common problem BGS technicians encounter with self-installed systems is sensor placement — doors with multiple entry points, windows that are accessible but overlooked, or cameras with blind spots. A professional installation starts with a security assessment, not with mounting hardware.
How does a home security system connect to emergency services?
When a professionally monitored alarm is triggered, the signal travels from the sensor → control hub → monitoring center via cellular or internet connection. Operators at the monitoring center attempt to reach the homeowner via a pre-established contact list. If the alarm is confirmed or the homeowner cannot be reached, the center contacts the appropriate emergency service — police, fire department, or ambulance — and provides the address and alarm type.
This process happens within seconds of the alarm trigger. BGS Security’s monitoring is provided 24 hours a day, every day of the year, including holidays.
Do home security systems protect against fire and carbon monoxide?
Yes. A fully integrated home security system includes smoke detectors, heat sensors, and carbon monoxide detectors connected to the same control hub as the intrusion sensors. When these trigger, the same monitoring center that handles break-in alarms will dispatch the fire department or emergency services.
AJAX FireProtect 2, used in BGS installations, detects both smoke and heat, reducing false alarms from cooking steam while ensuring genuine fires are caught early. CO detection is handled by a separate device that connects to the same AJAX hub.
These sensors make the security system a comprehensive life-safety platform, not just a burglary deterrent.
What makes AJAX security systems different from standard alarm systems?
AJAX is a professional-grade wireless security platform used by BGS Security for all New Jersey installations. The key differences from standard consumer alarm systems:
- Two-way encrypted communication between every device and the hub — the hub knows immediately if a device is tampered with or loses contact
- Anti-jamming detection — if a radio jammer is used near the property, the hub detects it and triggers an alert
- Cellular backup built-in — the hub maintains its monitoring connection even if the internet router is unplugged or power is cut
- Tamper detection on every device — opening a sensor casing triggers an alarm
- Battery life reporting — the app shows battery levels for every device so nothing fails silently
This is the same platform used by professional security companies in Europe and increasingly in the US for commercial and residential applications. See AJAX products →

Frequently Asked Questions: Home Security Systems
Is a home security system worth it for a New Jersey home?
Yes. The average loss from a residential burglary in the US is approximately $2,800 in property. A professionally monitored system deters break-ins before they occur — studies consistently show that homes with visible security systems are passed over by burglars — and provides emergency response for fire and medical events as well.
How long does installation take?
A standard BGS Security installation for a single-family home takes 3–6 hours. Larger properties or those requiring extensive camera coverage may take a full day. The home is fully functional and protected before the technician leaves.
What happens if the power goes out?
AJAX hubs include a built-in backup battery (typically 20+ hours) and maintain their monitoring connection via cellular radio, independent of your home’s internet router or power supply.
Can I monitor my home remotely?
Yes. The AJAX app provides real-time status for every sensor, live camera viewing where cameras are installed, and the ability to arm or disarm the system from anywhere.
What is the monthly fee for professional monitoring?
BGS Security monitoring plans are listed at bgs.us/prices. Pricing depends on the monitoring level and system configuration.
Do I need a permit for a security system in New Jersey?
Some New Jersey municipalities require an alarm permit, typically a one-time or annual fee of $25–$50. BGS Security can advise on your specific municipality’s requirements during the consultation.
What is the contract length?
BGS Security offers flexible terms. Contract specifics are discussed during the consultation and outlined before any agreement is signed.
Can the system be expanded after installation?
Yes. AJAX systems are fully modular — additional sensors, detectors, and cameras can be added at any time without replacing the hub or existing devices.
