Common Questions

Frequently Asked Questions

Everything you need to know before booking your free consultation.

Do you offer free consultations and quotations?
Yes — our consultations and site surveys are completely free with no obligation. We visit your property, assess your requirements, and provide a detailed fixed quotation before any work begins.
Which areas do you cover?
We are based in North West London and cover all London boroughs — Central, East, West, South, and North London. Contact us to confirm availability for your specific area.
Do you install systems for both homes and businesses?
Absolutely. We work across residential properties, commercial premises, retail units, offices, and large development projects. Our engineers are experienced in both domestic and commercial-grade installations.
How long does installation take?
Most residential installations are completed in a single day. Larger commercial or multi-system projects may take 2–5 days. We'll give you a clear timeframe during your site survey.
Can I control my system from my smartphone?
Yes. All modern CCTV, alarm, access control, and intercom systems we install include smartphone app integration, so you can monitor and control your security from anywhere in the world.
Do CCTV cameras work at night?
Yes. The cameras we install feature full-colour night vision and infrared capability, providing clear detailed footage in complete darkness.
Do you repair existing security systems?
Yes. We diagnose and repair existing CCTV, alarm, intercom, and access control systems regardless of the original installer. Contact us with details and we'll advise accordingly.
Do you work with contractors and developers?
Yes. We regularly partner with contractors, builders, and property developers on new-build and refurbishment projects. We can work to specification or provide our own system designs.
Can you install multiple systems together?
