Outdoor security lights and sensors

Security lighting works when it lights the right place at the right time without blinding anyone or switching on all night.

Motion-activated lights at gates, driveways, side passages and back doors help people move safely after dark and deter intruders. Their effectiveness depends on placement: sensors aimed to detect approach paths, lights angled to illuminate faces and steps rather than the street, and settings that avoid constant triggering.

Installation guides cover what a fitting or appliance needs from the electrics before it goes on the wall or ceiling.

False triggers are common in gardens with moving palms, passing cars or pets. Adjusting sensor sensitivity, range and angle, or using separate sensors, keeps lights from cycling all night. Glare onto neighbouring properties should be avoided.

01In short

The points that matter most

  • Cover approach paths

    Gates, drives, side passages and doors.

  • Avoid glare

    Angle lights down and away from neighbours.

  • Tune sensors

    Reduce false triggers.

02Detail

Placement and settings

  • Sensor height and angle

    Positioned to detect people, not passing traffic.

  • Light direction

    Illuminating paths and faces.

  • Timers

    How long lights stay on after detection.

  • Wiring and switching

    Security lights can be wired with a manual override switch so they can be held on when needed, and on their own circuit so a fault does not affect indoor lighting.

03Checklist

Before installation

  • Walk the property at night

    Note dark spots.

  • Note moving objects

    Palms, flags, pets.

  • Consider cameras

    Lighting affects camera images.

04Questions

Questions people ask

Why does my light keep switching on?
Sensors may detect movement from trees, cars or animals.
Can sensors be separate from lights?
Yes, allowing better placement.
Do security lights need to be bright?
Well-aimed moderate light is often more effective than glare.
Should security lights stay on all night?
Usually not; sensor-triggered lights draw attention when something moves and avoid lighting neighbours all night.
Do outdoor sensors cope with the heat?
Choose units rated for outdoor use and high temperatures; direct afternoon sun on a sensor can affect its performance.
