Protecting your property should be about peace of mind, not long-term paperwork and endless monthly costs. At i-Spy CCTV, we believe that when you buy a security system, you should actually own it. That is why we specialise in the Dahua AirShield, a cutting-edge, wireless intruder alarm system that puts you in total control without the "subscription trap" of traditional providers.
Whether you are looking to secure a family home in Bristol or a commercial warehouse in Cardiff, our goal is to provide unparalleled protection through meticulous installation and honest, expert advice.
Why Choose i-Spy CCTV for Your Security?
Choosing the right security partner is as important as choosing the right equipment. We know that the industry is often filled with high-pressure sales tactics and "limited time offers" that never actually expire. At i-Spy CCTV, we do things differently.
1. Honest Advice with No Hard Sell
We are security experts, not salesmen. When you book a survey with us, we look at your property through the eyes of an intruder. We provide a bespoke security design tailored to your specific vulnerabilities. If you don’t need a sensor in every single room, we will tell you.
2. Professional and Meticulous Installation
Our reputation is built on the quality of our work. We take pride in clean, tidy, and swift installations. Because the Dahua AirShield is a wireless system, we can secure your entire premises without lifting floorboards or trailing unsightly cables across your walls.
3. Equipment You Actually Own
This is the biggest difference between i-Spy CCTV and the big "national" brands. When we install your alarm, you own the equipment. There are no ongoing fees to keep the system active, and you aren't "renting" your sensors.

The Comparison: Dahua AirShield vs ADT & Verisure
If you have been researching burglar alarms, you have likely come across names like ADT and Verisure. While they are well-known, they often rely on a business model that prioritises monthly subscriptions over customer ownership.
No Monthly Fees vs Permanent Costs
The most significant advantage of the Dahua AirShield system installed by i-Spy CCTV is the financial freedom it offers. Most national providers require a monthly fee (often ranging from £30 to £60+) just to keep your app working or your system "monitored." Over five years, that can add up to over £3,000 in fees alone.
With our Dahua AirShield installation:
- Zero monthly subscriptions for app usage.
- No "locked" equipment that stops working if you cancel a contract.
- Complete ownership of every sensor, hub, and siren from day one.
Comparing the Technology
While brands like Verisure offer "fog" systems or specific monitoring, the Dahua AirShield matches or exceeds them in core security features. It is a Grade 2 professional security system, meaning it meets the stringent standards required by insurance companies for high-level protection.

Cutting-Edge Features of the Dahua AirShield
The Dahua AirShield isn't just a bell box on a wall; it is a seamlessly integrated security ecosystem. Here is why it has become our most recommended system for both residential and commercial clients across the South West and South Wales.
Full Smartphone Control
Gone are the days of rushing to a keypad before the timer runs out. With the DMSS app, you can arm or disarm your system from anywhere in the world.
- Instant Push Notifications: If a sensor is triggered, your phone alerts you immediately.
- Visual Verification: If you have a PIR-Cam installed, the system will send live snapshots of the event directly to your phone, so you can see if it’s a genuine intruder or just a pet.
Wireless Reliability
Some people worry that wireless alarms aren't as stable as wired ones. The AirShield uses Frequency Hopping technology and AES128 encryption to ensure the connection between the sensors and the hub is robust and unhackable. It constantly "polls" the sensors to make sure they are online and healthy.
Integration with CCTV and NVR Systems
Because we are CCTV specialists, we love how the AirShield talks to your cameras. We can link your alarm to a Dahua NVR (Network Video Recorder). If an alarm sensor is triggered, your cameras can automatically swing to that location and start recording in high definition. It provides a robust, multi-layered defence for your property.

Tailored Solutions: Residential and Business
Secure Your Home and Family
Your home is your sanctuary. Our residential installations focus on creating a tranquil and serene environment where you know your loved ones are safe. We offer pet-friendly PIR sensors that can distinguish between a human intruder and a cat or dog, ensuring you don't get false alarms while you are at work.
Robust Protection for Your Business
For our commercial clients in shops, offices, and warehouses, the Dahua AirShield provides a scalable solution. We can protect multiple entry points, loading bays, and office suites under one unified system. The ability to manage staff access through the app makes it an ideal choice for modern business owners.
Our Simple 4-Step Installation Process
We believe in transparency. Here is how we get your property secured:
- Consultation: We visit your site to understand your specific needs and concerns.
- Design: We create a bespoke plan, selecting the right mix of door contacts, motion sensors, and sirens.
- Installation: Our engineers carry out a meticulous, clean installation, usually completed in just a few hours.

Frequently Asked Questions
How much does a burglar alarm cost?
The cost depends on the size of your property, the number of doors and windows you want protected, and whether you want extras such as external sirens, keypad access, or PIR-Cam detectors. For a tailored price, the best option is to book a free survey so we can recommend the right setup for your home or business.
Do I need a monthly subscription?
No. One of the main benefits of a Dahua AirShield system installed by i-Spy CCTV is that you own the equipment outright. There are no monthly subscriptions required to use the app or keep the system active.
Can I control the alarm from my phone?
Yes. Using the DMSS app, you can arm and disarm the system, receive push notifications, and manage your alarm remotely. This gives you fast control and extra peace of mind wherever you are.
Are Dahua AirShield alarms pet friendly?
Yes. We can supply pet-friendly PIR sensors designed to reduce false alarms caused by cats and dogs. During your survey, we will advise on the best detector placement to suit your property and pets.
