Installing motion sensor lighting in your backyard is an easy way to add security and convenience to your outdoor space. With motion sensor lights, the lights turn on automatically when motion is detected, helping to deter intruders and light your way when you take your dog outside at night.
Why Install Motion Sensor Lighting?
There are several benefits to using motion sensor lighting in your backyard:
-
Deters intruders - Motion activated lights can startle and scare away potential intruders. The sudden brightness when the lights turn on makes them rethink entering your yard.
-
Saves energy - Unlike traditional porch and security lights that stay on all night, motion sensor lights only turn on when needed. This saves electricity and reduces your energy bill.
-
Provides safety - The automatic lighting provides increased visibility at night when you take out trash, walk the dog, or check on noises outside. This extra illumination gives you peace of mind and security.
-
Easy automation - With motion sensors, the backyard lights operate automatically without you having to flip a switch or remember to turn them on. The convenience makes your life easier.
Choosing the Right Motion Sensor Lights
When selecting motion sensor lights for your backyard, there are a few options to consider:
Sensor Type
-
Passive infrared (PIR) - PIR sensors detect body heat and motion. They work well for driveways, paths, and yards.
-
Microwave - Microwave sensors emit microwave pulses and measure disturbances. They work over longer ranges than PIR.
-
Dual technology - Combination PIR and microwave sensors avoid false triggers better than single technology sensors.
Detection Area
-
The detection area or range refers to the size of the area the sensor can "see" motion in. For larger yards, choose lights with longer 100+ foot detection ranges.
-
Look for wide 140-180 degree detection angles to provide full coverage. Narrow detection angles can miss motion outside those cones.
Light Bulb Type
-
Incandescent - Less efficient but with warmer light color.
-
LED - More energy efficient and last longer. Cooler light color.
-
Halogen - Compact, bright, long-lasting.
Features
-
Adjustable sensitivity - Lets you control how much motion is required to activate the light. Useful for reducing false triggers.
-
Timer settings - Adjusts how long the light stays on after motion is detected. 1-5 minute timers prevent lights staying on unnecessarily.
-
Daylight sensor - Convenient feature that prevents light from turning on in daylight hours. Saves energy.
-
Manual override switch - Lets you turn lights on/off manually as needed. Useful for maintenance and testing.
-
Weatherproof - Important for any outdoor fixtures to withstand weather elements. Ensure at least IP44 water resistance rating.
Choosing Lighting Fixture Types
There are several fixture types to choose from when installing motion sensor backyard lighting:
Security Flood Lights
-
Bright flood lights designed to mount under the eaves of your home or on poles/walls.
-
Provide powerful 700-3000 lumen illumination over large areas.
-
Ideal for driveways, backyard paths, and monitoring large areas.
Wall Lanterns
-
Subtle but stylish wall mounted lanterns with built-in motion sensors.
-
Offer decor aesthetic for backyard patios and door entries.
-
Many designs from modern to vintage are available to match home architecture.
Spotlights
-
Narrow but intense beams of light focused on highlighting architectural features.
-
Used to spotlight plants, landscaping, water features, or focal accent points.
-
Available as ground stake spots or wall mounts depending on needs.
Step Lights
-
Low profile lights designed to illuminate stairways and steps.
-
Cast a glow for better visibility on steps, paths, and changes in grade.
-
Help prevent trips, slips, and falls at night.
Tips for Installing Motion Sensor Lights
Follow these tips when installing your new motion sensor backyard lights:
-
Position the light 8-12 feet above the ground with sensor facing the area you want to monitor. This gives optimal range and detection area.
-
Angle floodlight fixtures 30-45 degrees downward to aim the light where it's needed.
-
For best coverage, mount lights in opposite corners of yard areas rather than one centralized light.
-
Avoid aiming the sensor at busy areas like pools or trees that may generate false triggers.
-
Test during day and night to ensure proper coverage. Adjust sensor angle and range as needed.
-
Consider connecting multiple lights to one sensor to provide coordinated lighting when motion is detected.
Maintaining Your Motion Sensor Lights
Like any fixture, motion sensor lights require occasional maintenance:
-
Clean the motion sensor lens gently with a soft cloth to remove dirt and debris that could impede performance.
-
Check that fixtures remain securely mounted. Tighten or adjust as needed.
-
Inspect wiring connections to make sure they are secure and free of corrosion.
-
Replace bulbs that have burned out for full illumination.
-
Test functionality regularly and replace malfunctioning units as needed.
-
Consider repainting fixtures every few years to refresh their appearance and maintain weather protection.
With the right placement and maintenance, motion sensor backyard lighting provides an unmatched combination of security, energy savings, and convenience. Following these guidelines and recommendations will help you successfully install motion detector lighting to illuminate and protect your backyard.
