Why Home Alarm Systems Are Critical in Perth (2025 Data)
Perth continues to experience property crime despite overall declining crime rates. Here's why alarm systems remain essential:
Key insight: Homes without alarm systems are 3x more likely to be burgled than protected properties. The visible alarm siren box alone acts as a powerful deterrent.
Types of Home Alarm Systems (2025 Options)
1. Monitored vs Unmonitored Alarm Systems
| Feature | Monitored Alarms | Unmonitored (Self-Monitored) |
|---|---|---|
| Who responds? | Professional monitoring center → Security/Police | You receive app notification (you respond) |
| Response time | 3-5 minutes (monitoring center dispatch) | Depends on when you see notification |
| Monthly cost | $40-$70/month | $0 (one-time equipment cost only) |
| Insurance discounts | 10-20% premium reduction (most insurers) | Limited or no discounts |
| Reliability | Redundant systems, battery backup, cellular | Relies on your phone/internet connection |
| Best for | Families, high-value homes, frequent travelers | Budget-conscious, tech-savvy homeowners |
Great White recommendation: For most Perth homeowners, monitored alarm systems provide superior protection. The monthly cost ($40-70) is offset by insurance savings within 2-3 years, and the peace of mind is invaluable when you're away from home.

Common Alarm System Mistakes to Avoid
❌ Mistake #1: Choosing Unmonitored "Bell Only" Alarms
Loud sirens alert neighbors but don't guarantee response. Studies show 60% of people ignore alarm sounds assuming it's a false alarm. Professional monitoring ensures verified response within 3-5 minutes.
❌ Mistake #2: Inadequate Sensor Coverage
Don't skimp on sensors to save $200. Burglars will find unprotected entry points. Minimum coverage: all ground-floor doors/windows + glass break sensors + motion detectors in main living areas.
❌ Mistake #3: No Cellular Backup
Relying only on internet connection is risky. Burglars can cut NBN lines. Cellular 4G/5G backup ensures alarm communicates with monitoring center even if internet is disabled. Worth the extra $15-25/month.
❌ Mistake #4: Visible Keypads Near Windows
Burglars watch you enter alarm codes through windows. Position keypads away from exterior sight lines. Consider smartphone arming/disarming instead of wall keypads.
❌ Mistake #5: Weak or Default Passwords
Change default installer/master codes immediately. Use unique 6+ digit codes. Don't use birthdays or PINs. Enable two-factor authentication on smartphone apps.
Perth-Specific Alarm Considerations
Climate & Weather Factors
- Hot summers: Outdoor sirens rated for 45°C+ temperatures (Perth regularly exceeds 40°C)
- Coastal corrosion: Stainless steel siren enclosures for coastal suburbs (within 5km of ocean)
- Storm power outages: Minimum 24-hour battery backup (Perth winter storms cause frequent outages)
- Windy conditions: Secure outdoor siren mounts to prevent vibration false alarms
NBN & Internet Reliability
Perth's NBN infrastructure varies significantly by suburb. For reliable alarm communication:
- NBN HFC/FTTC/FTTP areas: Ethernet connection to alarm panel works well
- NBN FTTN areas: Cellular 4G backup highly recommended (unreliable FTTN in some suburbs)
- Regional Perth: Cellular primary connection may be more reliable than internet
- Always add cellular backup: Prevents burglar disabling alarm by cutting NBN line
High-Risk Perth Suburbs
Properties in these suburbs benefit from enhanced alarm features (glass break sensors, video verification):

Frequently Asked Questions
What is the best home alarm system for Perth homes in 2025?
The best alarm system depends on your property type and needs. For most Perth homes, we recommend professionally monitored wireless alarm systems with smartphone integration. Top options include Bosch Solution 6000, Paradox MG5050, and Ajax wireless systems. These provide comprehensive coverage with door/window sensors, motion detectors, and 24/7 monitoring.
How much does a home alarm system cost in Perth?
Basic home alarm systems in Perth start from $1,200-$1,800 for equipment and installation. Mid-range professionally monitored systems cost $2,500-$4,000 installed. Premium smart alarm systems with advanced features range from $4,000-$6,500. Monthly monitoring fees are typically $40-$70 depending on features and response services.
Are monitored alarm systems worth it in Perth?
Yes, monitored alarms significantly improve security. When your alarm triggers, monitoring centers verify the threat and dispatch security or police within 3-5 minutes. This is critical when you're away or asleep. Many Perth insurers also offer 10-20% premium discounts for monitored systems, offsetting monthly monitoring costs within 2-3 years.
Should I choose wireless or wired alarm systems for my Perth home?
Wireless alarm systems are ideal for existing homes, rental properties, and heritage buildings where wiring is difficult. They're faster to install and more flexible. Wired systems suit new constructions or major renovations where running cables is practical. Modern wireless systems are just as reliable as wired, with encrypted signals and long battery life (2-5 years).
Can burglars disable alarm systems?
Properly installed modern alarm systems are difficult to disable. Key protections include: cellular backup (works if internet is cut), battery backup (works if power is cut), encrypted wireless signals (can't be jammed easily), tamper sensors (triggers alarm if panel is opened), and external siren boxes mounted high (difficult to access). Professional installation is critical for security.
Do alarm systems work with pets?
Yes! Pet-immune motion sensors (PIR detectors) are designed to ignore animals up to 25kg while still detecting human intruders. These sensors analyze heat signature size and movement patterns. They work reliably with dogs and cats in most situations. Ensure your installer knows you have pets and positions sensors correctly (avoid pointing at pet doors or favorite sleeping spots).
How long do alarm system batteries last?
Control panel backup batteries last 3-5 years and cost $50-$120 to replace. Wireless sensor batteries last 2-7 years depending on brand (Ajax 5-7 years, most others 2-5 years). Systems notify you 30+ days before batteries die. During power outages, backup batteries keep systems running for 12-24 hours (longer with premium systems).
Should I get CCTV cameras with my alarm system?
We strongly recommend combining alarms with CCTV. Alarms detect intrusion and trigger response; cameras provide visual evidence and identification. Integrated systems offer video verification (monitoring centers see footage during alarms, reducing false alarm charges). Budget $3,000-$5,000 for 4-6 camera CCTV system alongside alarms. Many clients install alarms first, then add cameras within 6-12 months.
