【Easy Installation】Sensor and receiver come pre-paired from the factory – just plug the receiver into an outlet and mount this motion sensor with screws or double-sided tape at your desired location. Plug and play.
【Loud Volume up to 110dB】This motion sensor alarm is loud enough – volume reaches up to 110dB with 5 adjustable levels (Mute-110dB) – to instantly alert you when a small cat wants to come inside, so you can open the door right away, or when a small dog wants to go out, letting you know your dog wants to get outside.
【55 Ringtones】This motion detector offers up to 55 ringtones to choose from – pick your favorite. A gentle “ding dong” instantly notifies you when a customer walks into your store; an urgent “Alarm Sound” alerts you immediately when an elderly person gets out of bed.
【High Sensitivity + Adjustable Detection Range】This PIR sensor with advanced IR tech quickly detects motion from 6.5 to 26 feet with high sensitivity. The detection range is adjustable – this motion detector alarm accurately detects within 15° vertically and 100° horizontally, and accurately distinguishes human movement from false signals.
【500ft Signal Range & Expandability】Reliable 500FT range between this outdoor motion sensor and receiver ensures full coverage – ideal for larger spaces. It is expandable: 1 sensor can pair with up to 50 receivers.
