Excellent product!

A little expensive for what it is, it works well
From 1 to 10 the sound is loud about 7. Enough to alert neighbours and may be worry an intruder. Needs to hide it, because it is battery operated, if the intruder spot it, will be easy to switch it off. Require a hub, expensive as well. It does the job.

YoLink Outdoor Security Siren - Turns Your System into a Serious Alarm
Loud 110 dB siren that needs no mains power.Pros:- Extremely loud and effective- Wireless with long battery life (over a year on 2 AA batteries)- Integrates perfectly with the full YoLink ecosystem- Can be triggered by door/window sensors, motion sensors, and more- Full control and arm/disarm via the phone appCons:- Requires the YoLink Hub (like all their devices)Combined with my other YoLink sensors (door/window, motion, temperature), this turns the whole setup into a top-end smart alarm system with incredible range thanks to LoRa technology. Perfect for large properties.Would I recommend? Yes, 5 stars.
