Pack of 8 Door & Window Entry Alarm

The Home Security System with a 90dB siren alarm not only delivers a strong emotional shock to intruders but can also wake you up to prevent unpleasant surprises. This widely used door and window alarm is perfect for homes, offices, hotels, apartments, garages, dorms, or even campers. The wireless magnetic sensor is great for deterring burglars and alerting you to unwanted entry or exit-for example, letting you know when children open doors or windows to prevent them from going outside. It's also handy if you have a pool, so you know when a door has been opened. Installation is simple with double-sided adhesive tape-no wiring or screws required. You can attach it to windows, doors, drawers, cupboards, and more. Each sensor consists of an alarm and a magnetic contact, placed less than 1 cm apart-one on the door or window and the other on the frame. When the contact is broken, the alarm sounds automatically. Each unit includes 3 LR44 batteries; just open the battery compartment and remove the paper blocking the contact to get it working perfectly.
