Smart Home & Security
Installation in Crawley
Control, Monitor, Protect

A properly wired smart home does not rely on batteries, Wi-Fi plugs, or cloud services that disappear when your broadband drops. We install hard-wired systems that work reliably — and protect your home even when the internet does not.

Hard-wired installations that work reliably — no battery changes, no signal dropouts, no cloud dependency

What Are Smart Home & Security Installations?

Smart home installation covers the electrical infrastructure that powers and connects automated systems in your home. This includes smart lighting (app-controlled, scheduled, and scene-based), CCTV camera systems, intruder alarm systems, video doorbells, automated gate and garage door controls, and whole-home audio.

The key difference between a professional installation and a DIY smart home is reliability. Consumer-grade Wi-Fi plugs and battery-powered cameras work well in demonstrations, but they fail when you need them most — during power cuts, broadband outages, or when batteries die at 2am.

A professionally installed system uses hard-wired power, dedicated data cabling, and battery backup where appropriate. CCTV cameras record locally to an NVR (Network Video Recorder), not just to a cloud service. Alarm systems have battery backup and cellular communication, so they work even if your broadband and power are both out.

Lambourn Electrical Services designs and installs smart home and security systems across Crawley, Horsham, Redhill, Reigate, and the wider Surrey and Sussex area. We handle the electrical wiring, data cabling, and system configuration — giving you a single point of contact for the entire project.

Why DIY Smart Home Systems Let You Down

Battery-powered security cameras are the most common DIY smart home device — and the most unreliable. Batteries last 2–6 months depending on activity. When the battery dies, the camera stops recording. Many homeowners discover this only when they need footage of an incident that was never captured.

Wi-Fi-dependent systems create a single point of failure. If your broadband drops (which happens more often than most people realise), every cloud-connected device in your home stops working simultaneously. Smart locks, cameras, doorbells, and alarm systems all go offline at once.

Consumer-grade smart plugs and switches are not designed for the sustained loads they often carry. Using a smart plug to control a high-draw appliance (a heater, a dehumidifier, an air conditioning unit) can cause overheating. Professional smart switches are rated for the load and wired into properly protected circuits.

Self-installed CCTV systems frequently suffer from poor placement, inadequate night vision coverage, and lack of weather protection. A camera pointed at a window creates glare at night. A camera placed too high loses facial recognition capability. A camera without a drip loop allows water to run down the cable and into the housing.

Smart Home & Security Systems: Technical Detail

CCTV Systems: We install IP-based CCTV systems using PoE (Power over Ethernet) cameras connected to a dedicated NVR. PoE eliminates the need for separate power cables — a single Cat6 cable carries both data and power. We recommend 4MP or 8MP cameras with IR (infrared) night vision, IP67 weatherproofing for outdoor units, and H.265 compression for efficient storage.

NVR units are installed in a secure location (utility cupboard, loft, or dedicated cabinet) with sufficient hard drive capacity for 14–30 days of continuous recording. Remote viewing is configured through the manufacturer's app, allowing you to check live footage and review recordings from anywhere.

Intruder Alarm Systems: We install Grade 2 alarm systems that comply with BS EN 50131 (the European standard for alarm systems). These include wired PIR sensors, door/window contacts, a control panel with battery backup, and a combination of audible sounder (external bell box) and monitored alert (via mobile app or monitoring station).

Video Doorbells & Access Control: Hard-wired video doorbells provide reliable power (no battery charging), better video quality, and faster response times than battery models. We also install electric gate controllers, garage door automation, and keyless entry systems for properties requiring enhanced access control.

Smart Lighting: We install hard-wired smart switches (such as Lightwave, Rako, or Lutron) that replace standard switches. These provide app control, voice control (via Alexa or Google Home), scheduling, and scene-setting without relying on smart bulbs. The switches operate locally even without internet, and the lighting circuit remains functional as standard switches if the smart system is ever disabled.

Network Infrastructure: For homes with multiple smart devices, a robust network is essential. We install structured cabling (Cat6/Cat6a) to key locations, and can install additional Wi-Fi access points for comprehensive coverage. A well-designed network eliminates the buffering, dropouts, and latency issues that plague Wi-Fi-only smart homes.

All electrical work — power circuits for cameras, data cabling containment, consumer unit modifications, and outdoor wiring — complies with BS 7671 and is certified under Part P where applicable. We handle the entire installation from electrical infrastructure to system commissioning.
