You won’t have to worry about drilling holes or making other modifications, so wireless is an attractive option for renters, historic homes, or buildings with significant interior brick, stone, or marble construction. Renters or homeowners who change residence will also be able to take advantage of the portability of most wireless systems—simply disconnect and reconnect at your new address. Frontpoint is a great option for those who are interested in a portable home security system. Frontpoint requires DIY installation, but if you’d rather have someone install the system for you, Vivint is another good wireless contender with professional installation. 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. Just make sure you stay on top of changing out your batteries so you know they’re always operating at peak performance.
