The potential drawback of wireless is its reliability. Just like Wi Fi routers or cellphones, wireless security systems are subject to various types of interference, that can cause your sensor to fail to respond or to respond unpredictably for example, triggering a false alarm. Electromagnetic interference can come from many other devices, including baby monitors, remote controls, power lines, microwave ovens, and fluorescent lighting. Structural interference comes from walls, floors, ceilings, or things like metal filing cabinets. However, these issues are rare. To help counter potential issues, each wireless sensor contains its own battery, which works great, especially in a power outage.
