Choosing Your Home Security System

1. The 3 main alarm categories

Before comparing brands, understand the category. 95% of customer/installer disputes stem from a misunderstanding of what is actually being sold.

🛎️ The “Local” Alarm (Self-Contained)

A control panel, sensors, and a siren: that’s it. In the event of an intrusion, the siren blares (110 dB on average) to scare off the intruder and alert the neighborhood. No call to a center, no dispatch service. Advantage: zero recurring fees. Disadvantage: if you are on vacation and no one hears the siren, you will only discover the burglary upon returning. Suitable for dense urban apartments and tight budgets.

📡 The Connected Alarm (Notification-based)

Same principle as the local alarm, but the control panel is connected to Wi-Fi or 4G. In case of an alert, you receive a notification on your smartphone and can check cameras remotely. You decide yourself whether to call 911, a neighbor, or head home. This is the segment that has exploded since 2020 (Verisure, Ring, Ajax, etc.). Suitable for smartphone-savvy professionals who travel infrequently.

🛡️ Professional Monitoring

The alert is sent to a professional monitoring center operating 24/7. An operator performs a verification (video or audio), then acts according to the protocol: contacting a trusted neighbor, dispatching a private security guard, or calling 911. This is the most expensive option ($40-$90/month) but the only one where someone takes action while you are away. Essential for businesses, and recommended for isolated homes and high-end properties.

2. Wireless or Wired?

The debate is largely settled in 2026. Encrypted two-way wireless radio (technologies like Jeweller, S2, Honeywell SiX) is as reliable as wired systems and requires no drilling into walls. Wired systems remain relevant only for new construction where cables are run alongside electrical wiring, or for professional sites requiring total network autonomy.

For 99% of homeowners, go with a wireless system. Check two things: battery life (at least 5 years for peace of mind) and the presence of a 4G/GSM backup in case of an Internet outage — without this, your connected alarm becomes silent if your broadband connection is cut.

3. Professional Monitoring: Useful or Marketing Hype?

The real question is: who takes action when the alarm goes off? A neighbor woken up at 3 a.m. by your siren will not call 911 (this is statistically proven). If you are on vacation 4,000 miles away, you can’t do anything. Professional monitoring solves exactly this problem.

That said, watch out for marketing gimmicks. Check:

• The monitoring center’s credentials (in the United States: state-level licensing for security companies). Without proper licensing, the operator may lack the authority to coordinate with local law enforcement.
• The number of simultaneous operators. A small center can be overwhelmed during a storm and process your alert with a 20-minute delay.
• On-site response costs. Many contracts advertise “included response” but charge $80 to $150 for every dispatch. Read the Terms and Conditions.
• Contractual response time. Serious standard: less than 30 minutes in urban areas. Anything over an hour is just for show.

4. The 8 criteria to check before signing

• 1. Contract length. Contracts range from 0 (no commitment) to 60 months. A reputable installer offers a maximum of 12 months. Anything longer is often used to recoup the cost of “free” equipment: refuse it.
• 2. Equipment ownership. Do you own the equipment, or is it leased? If leased, what happens at the end of the contract? Is there a free return or a penalty fee?
• 3. Sensor coverage. How many sensors are included in the package, and how many are needed to actually cover your home? A detached house typically requires at least 4 door/window sensors + 2 motion detectors.
• 4. Alarm verification. Video, audio, or both? Audio-only verification often misses subtle intrusions (pets, drafts, etc.). Video is more reliable but raises privacy concerns — check local privacy regulations.
• 5. Equipment warranty. 2 years minimum. Good installers offer 5 years.
• 6. After-sales service. What is the response time for repairs? How many years are spare parts available? An uncertified system can become a burden after 18 months.
• 7. Insurance compatibility. Some homeowners or renters insurance providers require specific certifications to grant a premium discount or activate personal-property coverage for burglary. Ask for the list of approved brands before signing.
• 8. Cancellation terms. Notice period? Fees? Equipment recovery? In 80% of disputes, the customer had not read this section.

5. What is the real cost?

Three cost categories to anticipate:

• Hardware. Entry-level DIY kit: $150-$300. Mid-range kit with outdoor siren and camera: $500-$900. Professional installation with control panel and 6+ sensors: $1,200-$2,500.
• Subscription. $0/month for standalone DIY. $9-$19/month for basic notifications. $39-$89/month for full professional monitoring.
• False Alarms. $0 for most providers for the first few false alarms, then $50-$150 per incident. Check your service agreement for specific terms.

Over 5 years, the total cost of a connected entry-level system is around $1,100. A full professional monitoring setup: $3,500-$5,500. To put this in perspective: the average deductible for homeowners or renters insurance is $250-$500, and the median loss from a burglary in the United States is approximately $3,000.

6. Common mistakes to avoid

• ❌ Buying a kit without assessing your home. A glass back door doesn’t just need an entry sensor; it needs a glass-break sensor. A common mistake: 4 sensors on front windows and zero in the back.
• ❌ Choosing based solely on price. A $9/month subscription without professional verification is purely decorative. Price isn’t the right metric: the action chain is.
• ❌ Hiding the alarm. A visible outdoor siren and a sticker at the entrance have a proven deterrent effect: 60% of burglars avoid sites with visible security systems.
• ❌ Neglecting maintenance. Batteries need changing every 3-5 years, firmware updates are essential, and sirens should be tested monthly. Without this, your system may fail when you need it most.
• ❌ Underestimating camera coverage. Pointing a camera at public property beyond your own premises can lead to privacy disputes or legal issues. Always ensure your cameras focus on your own property.

7. Do you need to register your alarm?

In the United States, requirements for alarm registration vary by municipality. Many local jurisdictions require you to register your alarm system with the local police department to avoid fines for false alarms. Always check your local city or county ordinances. In an emergency, always dial 911.

Also, remember to notify your homeowners or renters insurance provider. Installing a monitored security system often qualifies you for a 5% to 15% discount on your annual premium. Over 10 years, this can cover a significant portion of the system’s cost.
