DSC BV500 Bravo 5 Ceiling Mounted 360 Degree Motion Detector
US
£44.33 12.2 360

The DSC BV500 is a hardwired passive infrared motion detector designed for flat-ceiling installation. It provides 360-degree coverage, with a maximum detection diameter of 12.2 m when mounted at 3.6 m, and suits residential or commercial alarm systems.

★ Ideal for

This is not the quietest motion sensor available because no alarm sound level is specified and it is a hardwired detector that relies on an external alarm system for audible alerts.

Honeywell IS335 Motion Sensor
US
£16.97 17.07

The Honeywell IS335 is a hardwired indoor PIR motion detector with a 40 ft x 56 ft detection range and selectable pet immunity for animals up to 80 lb. Its sealed optics, consistent Fresnel-lens sensitivity, and 2,000-lux white-light immunity help reduce false alarms, making it suitable for residential alarm systems.

★ Ideal for

It is not suitable for the quietest motion sensor available because the IS335 is a hardwired PIR detector with no published alarm sound level, although its sealed optics and pet-immunity setting can help reduce false alarms.

Honeywell IS3035V PIR Motion Detector
US
£31.02 12 x 17

The Honeywell IS3035V is a hardwired PIR motion detector with a 12 x 17 m coverage area, selectable pet immunity, dual-slope temperature compensation, and uniform-sensitivity Fresnel optics. It suits residential or commercial wired alarm systems, particularly installations needing reliable coverage and reduced false alarms.

★ Ideal for

It suits the search for the quietest motion sensor because it is a hardwired detector with no built-in audible alarm sound level specified, so it does not add a local siren or alert noise.

Nanoleaf Sense+ Smart Wireless Switch With Built-in Motion and Daylight Sensors CGC7VVZSTH
US
£22.18 6-10 120 1+

The Nanoleaf Sense+ is a wireless, battery-powered smart switch with passive infrared motion sensing and daylight sensing. It supports programmable lighting controls, can be wall-mounted or used as a portable remote, and suits renters and smart-home users who want automated lighting without hardwiring.

★ Ideal for

For a quiet motion-sensor setup, it is suitable because it uses passive infrared sensing and is designed to automate compatible lights without a documented audible alarm, although no alarm sound level is specified.
