  • 5 Advantages and Disadvantages of Wired and Wireless Sensor

    InstallationCostMaintenanceConnectivity and SecurityFlexibility and ScalabilityA quick, straightforward installation is one of the main benefits of wireless sensor systems. When you consider that the vast majority of those adopting the technology will be doing so in an existing building, it’s not hard to see why this easy retrofit solution has gained so much traction. Wireless systems could be your only viable option where hard wiring is difficult or impractical, such as in heritage buildings, glass meeting rooms, and other situations where there are construction limitations. For example, while running wires between buildings could be prohibitive, you could easily connect a neighbouring building to the network with wireless devices. Installing wireless sensor systems doesn’t require any drilling, wiring or structural building changes. That means reduced installation costs, minimal disruption to your workforce and interiors, and a system you can get up and running much sooner. In contrast, a wired-in sensor system means you’ll need to hire an electrician and mo...
