Motion Sensor Installation Questions

Every question we get asked about motion sensor installation, answered straight.

Questions

How It Works

  • Can a motion sensor be added to an existing light fixture?

    Yes. The sensor head is wired into the existing junction box or inline with the fixture. The main check is whether the existing wiring and box can support the sensor and the connected load. Our partners assess this during the on-site estimate visit.

  • How does a motion sensor work on a 3-way switch circuit?

    The traveler wire must be identified and connected correctly before the sensor is fitted. If that step is skipped, one switch position stops working. Our partners trace each conductor individually before making any connection in a 3-way setup.

  • Will the sensor trigger from pets, passing cars, or wind?

    It can, if sensitivity is left at the factory setting. During installation, sensitivity is adjusted to match the location, and the field of view is aimed away from the street. A walk test confirms the sensor responds to the right movement and not to background activity.

  • What happens if I leave the area dark and delay the install?

    An unlit driveway or entry is a straightforward approach route at night. Dark zones around gated entries and long driveways are the areas most likely to be used without detection. Delaying means that risk stays in place every night until the sensor is wired and aimed.

  • Do motion sensors work indoors as well as outside?

    Yes. Indoor installs cover hallways, entries, and stairwells. The placement and sensitivity settings differ from outdoor use because the detection field needs to cover foot traffic without catching movement in adjacent rooms. Both scenarios are handled in the same service visit.

  • What is checked before the sensor is connected?

    The breaker is shut off first, then a voltage tester confirms the circuit is dead at the junction box. Each wire is identified before any connection is made. After wiring, the sensor is tested for activation, timing, and coverage before the job is signed off.
