This is a Raymay anti-crime buzzer with waterproof and reflective stickers. It features a flashing light that works in conjunction with the alarm sound and high-intensity wide-angle reflective stickers, making it useful for crime prevention at night. It is water-resistant (IPX4) and emits a loud 92dB alarm sound (measured 1m in front of the main unit). It uses three button batteries (LR44) and comes with a safety neck strap.
