Security Systems & CCTV: Costs, Installation & How to Get Quotes

But security installations vary enormously in cost and quality. How much should you expect to pay for a CCTV system? What's the difference between wired and wireless alarms? Do you need professional monitoring? And how do you find a trustworthy installer who won't overcharge or recommend unnecessary equipment? This guide explains security system costs, types of equipment, installation requirements, and how SpecConnect can connect you with verified security specialists quickly.

Types of burglar alarms

• Wired alarms: sensors connected by cable to control panel — reliable, no batteries, harder to interfere with. Best for new builds and commercial properties.
• Wireless alarms: sensors communicate via radio frequency — easy to install, no cable runs, portable. Best for existing homes and rental properties.
• Smart alarms: WiFi-connected, app-controlled — remote arming/disarming, notifications, smart home integration. Best for tech-savvy homeowners.
• Monitored alarms: alarm triggers alert to monitoring centre who contact police/keyholder. Most police forces won't respond to unmonitored bells-only alarms.

Types of CCTV systems

• Analogue CCTV: cameras connected to DVR by coaxial cable — affordable, reliable, 720p-1080p resolution. Best for budget installations.
• IP CCTV: cameras connect to NVR via ethernet or WiFi — high resolution (2MP-8K), advanced features, remote viewing. Best for new installations and commercial.
• Wireless CCTV: battery or solar-powered via WiFi — easy install, no cables. Best for sheds, outbuildings, rental properties.
• Cloud storage (Ring, Nest, Arlo): access anywhere, £3-£10/month per camera. Local storage (DVR/NVR): no monthly fees, more privacy but can be stolen.

NSI or SSAIB certification: why it matters

NSI (National Security Inspectorate) and SSAIB (Security Systems and Alarms Inspection Board) are the UK's leading certification bodies for security installers. Many home and business insurance policies require NSI/SSAIB-approved systems for claims to be valid. Monitored alarms from approved installers get priority police response. Systems are designed to British Standards (BS 8418 for CCTV, BS 8243 for intruder alarms). Always verify NSI or SSAIB approval before hiring a security installer.

Do you need planning permission for CCTV?

Domestic CCTV usually does NOT need planning permission if cameras don't protrude more than 1 metre from the wall and the property is not listed or in a conservation area. You MUST comply with GDPR: cameras should only capture your own property, signage is required if cameras capture public areas, and footage must be stored securely and deleted after 30 days unless needed for evidence. Businesses must register with the ICO.

How to avoid cowboy security installers

• ❌ High-pressure sales tactics ('special offer ends today')
• ❌ Recommends far more cameras/sensors than you need
• ❌ No NSI or SSAIB certification
• ❌ Demands large upfront payment
• ✅ Get 2-3 written quotes from NSI/SSAIB-approved installers
• ✅ Ask for a site survey (reputable installers survey before quoting)
• ✅ Verify NSI/SSAIB approval on their websites
• ✅ Use verified platforms like SpecConnect where installers are checked before joining
