Wireless Vibration Alarm With Remote Control

A small PC plastic alarm unit sounds off the moment it senses a knock or a lift, useful stuck to a bike frame, a shed door, or a gate that shouldn't move without you knowing. Touch sensitivity adjusts across seven levels, so a light tap on a door won't trigger it the same way a full attempt to pry it open will. Two mounting methods come with it: double-sided tape for a flat surface, or a cable tie for a bike frame or railing. It runs on three small button-cell batteries. Not included. The waterproof ring around the shell keeps rain and splashes out, so it can live outdoors year-round. A keychain-sized remote arms and disarms it from a short distance, and this listing covers four set options, from a single spare remote up to the full three-piece set with two remotes and the alarm body. Dimensions on the alarm body run about 96 by 42 millimeters. Weight depends on which set you choose.
