What Our Customers Say

“The team at Garrison were excellent and very helpful. They knew what I needed and helped explain how the system will work. After being broken into we felt better knowing we can control our alarm from our smartphones. Thank you for great service.”

Frequently Asked Questions
How much does a wireless alarm system cost?
Wireless systems are priced by the number of sensors and the coverage you need – we design the system on the phone and confirm everything in a written quote the same day. Wired systems start from $995 if cabling suits your home better.
Are wireless alarms as reliable as wired?
Modern supervised wireless systems are extremely reliable – sensors report in regularly, and the panel alerts you to any sensor or battery issue. Where a home is pre-wired, wired can still be the most cost-effective choice; we recommend honestly on the call.
How long do the sensor batteries last?
Typically 2-4 years depending on the sensor and traffic. The system supervises every sensor and warns you well before a battery dies – and battery swaps are simple.
Can a wireless alarm be professionally monitored?
Yes – with a 4G communicator your wireless alarm reports to our NZ-based 24/7 monitoring centre just like a wired system, from $35 + GST/month with no lock-in contract.
Is wireless right for a rental or apartment?
Wireless is ideal where you cannot or do not want to run cables – apartments, rentals and finished homes. Systems can even move house with you.
Can I add sensors later?
Easily – wireless systems extend without any recabling. Start with core coverage and add sensors, sirens or smoke detectors any time.
