Trespassers and burglars who operate under cover of darkness are out of luck if you have outdoor security lighting. Less darkness and shadow means fewer places for them to conceal themselves.

A video surveillance system and even certain home landscaping tips can make your property more secure, but security lighting offers a relatively easy way to bolster your home’s defenses.

Security lighting is also used by businesses, government institutions and the military. In residential settings, both indoor and outdoor security lighting can serve several purposes for homeowners, including:

  • Increasing the feeling of safety
  • Helping deter intruders
  • Aiding in the detection of intruders

Outdoor security lighting

Installing outdoor security lights provides an effective first line of defense against potential burglars and trespassers. You can help protect your property with different types of home security equipment, such as surveillance cameras and lights, but make sure that the devices are mounted out of reach, securely bolted and covered by wire mesh or other protective material.

Motion sensor light

A motion sensor light operates on the same principles as a motion sensor used with an indoor home alarm system. Sometimes referred to as a passive infrared sensor (PIR), a motion sensor light activates instantly when it detects movement.


The various types of outdoor security lighting also include floodlights. These outdoor security lights are also called high-intensity discharge lamps (HID lamps). Floodlights produce more visible light than fluorescent and incandescent lamps (found in motion sensor lights) and can be used with light timers or motion sensors.

Home security lighting for indoor use

Many security lighting systems for indoor security systems involve home automation. A lamp module can be incorporated with a wireless connection and synched with a smartphone so that homeowners can control their home security lighting remotely.

Indoor home security lighting can deter potential intruders by creating the appearance that your home is occupied and therefore a less desirable target. By adding home automation controls, you can also save money on electric bills since you won’t have to leave the lights constantly on.
