About Sensor & Motion Lights in Constantia

Motion-activated lights use Passive Infrared (PIR) sensors to detect body heat from people and animals, automatically switching on when movement is detected within their range. They are the ideal solution for areas that need lighting only when someone is present - driveways, garden paths, garage approaches, front doors, and side passages. By only activating when needed, sensor lights reduce energy consumption compared to permanently lit fittings while providing immediate illumination exactly when required.

PIR sensor lights come in two main configurations: integrated units where the sensor is built into the light fitting, and separate sensor-plus-light setups where an independent PIR sensor controls one or more light fittings. The separate configuration is more flexible as the sensor can be positioned for optimal detection while the lights are aimed for best illumination. Modern PIR sensors offer adjustable sensitivity, detection range (typically 6-12 metres), illumination duration (10 seconds to 10 minutes), and a daylight sensor that prevents activation during daytime.

In Constantia, we install sensor lights as both security deterrents and convenience features. For security, PIR-activated floodlights at property boundaries and entry points starttle intruders with sudden bright light. For convenience, sensor lights at front doors, garage approaches, and garden paths provide hands-free illumination for residents returning home after dark. We calibrate each sensor to avoid nuisance triggers from pets, passing traffic, and wind-blown vegetation while maintaining reliable detection of people approaching the property.

This is one of several specialist services we offer under lighting installation in Constantia. As part of our Constantia electrical team, we bring over 25 years of hands-on experience to every job.

When to Call for Sensor & Motion Lights

Call when you want automatic lighting at your front door, driveway, or garden paths, when you need security lighting that activates on movement, when existing motion lights are unreliable or triggering falsely, or when you want to add convenience lighting to outdoor areas.

Our Sensor & Motion Lights Process

1

Location Planning

We identify the optimal positions for sensor lights based on the areas you want covered, typical approach routes, and potential sources of false triggers (pets, trees, traffic).

2

Sensor & Light Selection

We recommend the right combination of sensor range, light output, and mounting style for each position. Integrated or separate sensor configurations are chosen based on the specific installation.

3

Installation & Wiring

Fittings are mounted at the correct height and angle, wired to an RCBO-protected outdoor circuit, and weatherproof connections are made. Cables are run through conduit where exposed.

4

Calibration & Testing

Each PIR sensor is calibrated for sensitivity, range, and duration. We test from multiple approach angles to confirm reliable detection and adjust the daylight sensor to prevent daytime activation.

Property owners in Constantia often combine sensor & motion lights with light fitting installation in Constantia and light switch installation & repair. We handle everything, so you only need one call.

Safety & Compliance

Motion sensor lights must be IP-rated for outdoor use (minimum IP44 for sheltered positions, IP65 for exposed areas). All outdoor circuits must be protected by an earth leakage device. PIR sensors should not be aimed at public roads or neighbouring properties to avoid nuisance lighting. Installation height of 2-3m provides optimal PIR detection for human-sized targets. All installations must comply with SANS 10142-1.

Sensor & Motion Lights Cost in Constantia

An integrated motion sensor floodlight costs R400-R1,200 installed depending on the light output and brand. Separate PIR sensors controlling existing lights cost R300-R700 per sensor installed. A typical residential installation of 3-5 motion sensor lights costs R2,000-R6,000. High-end models with adjustable zones, pet immunity, and app connectivity cost more. Cable runs from the DB board add to the cost based on distance.

Frequently Asked Questions

Why does my motion sensor light keep turning on by itself in Constantia?

False triggers are usually caused by pets walking through the detection zone, wind-blown vegetation, hot surfaces radiating heat, or passing traffic. We can adjust the sensitivity, detection zone, and mounting angle to eliminate false triggers while maintaining reliable human detection.

Can motion sensor lights work with LED bulbs?

Yes, modern PIR sensor lights are fully compatible with LED bulbs and most integrated units use LED as standard. However, some older PIR sensors have a minimum load requirement that very low-wattage LEDs may not meet. We ensure compatibility during installation.

How far can a motion sensor detect movement?

Standard residential PIR sensors detect movement at 6-12 metres, with a detection angle of 120-180 degrees depending on the model. For larger properties, we use long-range sensors or multiple sensors to achieve full coverage.

Do motion lights deter burglars?

Yes, security research consistently shows that sudden bright lighting is one of the most effective deterrents. Burglars prefer to operate in darkness and will typically avoid properties with motion-activated lighting. Combined with other security measures, sensor lights significantly reduce break-in risk.
