Types of Security Systems
The first choice is how the system connects and communicates.
Wireless Systems
Sensors communicate with the control panel via radio frequency.
- ✅ Easy, drill-free installation
- ✅ Portable (great for renters)
- ✅ Remote access via app
- ❌ Sensors require battery changes
Hardwired Systems
Sensors are physically connected to the panel with wires hidden in walls.
- ✅ Extremely reliable
- ✅ No sensor batteries to change
- ✅ Increases home resale value
- ❌ Professional installation required
- ❌ Difficult to move
Monitoring Options
Who watches your home when you're away?
Professional Monitoring
A 24/7 center monitors your alarm. If triggered, they call you to verify, then dispatch police/fire/EMS.
- Works even if your phone is off
- Often qualifies for insurance discounts
Self-Monitoring (DIY)
The system sends an alert to your smartphone. You are responsible for calling 911.
- No monthly fees (usually)
- Risky if you miss the notification
Security System & Monitoring Costs
"Home security cost" is split into upfront equipment/installation and ongoing monitoring.
Typical Costs
Smart Home Integration
Modern security is the hub of the smart home.
Smart Locks
Lock or unlock your door remotely for guests or dog walkers. Can be set to automatically lock when the system is armed.
Video Doorbells
See and speak to visitors at your door from your phone. A great deterrent for package thieves.
Environmental Sensors
Add smoke, carbon monoxide, and flood sensors to your alarm panel for complete home protection.
Frequently Asked Questions
Common questions about home security systems.
How much does a home security system cost?
Upfront equipment costs range from $200 for basic DIY kits to $1,000+ for comprehensive professionally installed systems. Monthly monitoring fees typically range from $20 to $60 depending on the provider and features (like video storage or smart home automation).
Do I need a landline for a security system?
No. Most modern systems use cellular connections (GSM/LTE) or Wi-Fi to communicate with the monitoring center. Cellular is considered the most secure because it can't be cut like a phone line.
What happens if the power goes out?
Security systems have a backup battery that keeps the panel running for 24 hours or more during a power outage. If the system uses cellular monitoring, it will continue to communicate with the monitoring center even if your Wi-Fi is down.
Is professional monitoring worth it?
Professional monitoring ensures that someone is watching your system 24/7. If an alarm triggers, they call you and then dispatch police/fire if needed. Self-monitoring relies on you seeing an app notification and calling 911 yourself, which can be risky if you're asleep or away from your phone.
Can I install a security system myself?
Yes, many modern wireless systems are designed for DIY installation and can be set up in under an hour. However, hardwired systems or complex setups with many cameras are best left to professional installers to ensure proper placement and wiring.
Are security contracts required?
Traditional alarm companies often require a 3-year contract in exchange for lower upfront equipment costs. However, many newer DIY-style companies offer month-to-month monitoring with no long-term commitment.
Do security systems work with pets?
Yes. Motion sensors can be configured to ignore pets under a certain weight (usually 40-80 lbs). Dual-technology sensors (combining heat and motion detection) are even better at preventing false alarms caused by active pets.
