× Wireless home automation
As the home automation industry has expanded with an ever-growing number of devices and services, companies are placing bets on which wireless protocols will dominate. The past few years the leaders have been Z-Wave and ZigBee. Companies are also using a variety of other standards including Crestron’s Infinet, Insteon, and proprietary technologies such as Lutron’s ClearConnect.
The home automation industry has expanded with an ever-growing number of devices and services
The popular ZigBee and Z-Wave short-range wireless technologies have proven ideal for the kinds of home-area networks that are becoming prevalent. Based on the IEEE’s 802.15.4 personal-area network radio standard, ZigBee is an open wireless standard. Z-Wave was developed by Zensys (later acquired by Sigma Designs) as a proprietary wireless standard. Z-Wave’s wireless mesh networking technology allows nodes to communicate with each other directly or indirectly through available relays if they’re within range. Out of range nodes can link with each other to access and exchange information. A Z-Wave network can have up to 232 nodes.
Some companies have sought to hedge their bets out of a desire to be more “manufacturer agnostic.” Bluetooth and Wi-Fi are gaining popularity with new low-power variations of these standards.
Smart doors and their benefits
Despite a wealth of features offered by the latest smart door locks — remote and location-based locking/unlocking; voice activation; timed access; emailed entry alerts; and integration with smart camera and lighting systems — most people still have limited knowledge of their capabilities. Only 14% of survey respondents described themselves as “very familiar” with what a smart lock can do. Even though most of them probably use smart access control solutions at their workplace.
While smart video surveillance solutions that can impact home automation are still in nascent stages, the potential is immense. Modern video analytics and surveillance technology have the capability to offer convenience to the connected homeowner and lower energy consumption. By determining the optimum lighting, heating and cooling needs of a connected home, smart video surveillance technology can drive down energy-related costs significantly. Smart cameras will also have an impact on the need for DVR/NVR products in an automated home, as analytics-driven video surveillance solutions that generate large amounts of data will reduce the need for these devices.

The resolution of an advanced radar sensor
Smart video surveillance technology can drive down energy-related costs significantly
Today, the resolution of an advanced radar sensor is high enough to enable not only presence detection, but also to provide advanced features for security, automation and well-being, all in one. Imagine for example, that the security sensor installed in an elderly parent’s home could also detect a fall having occurred, monitor the breathing of a baby or even leaks in the wall. Due to the unique field of view that radar provides as well as the multi-functional potential, this technology will be the key to the awaited convergence of smart home functionalities and minimization of home devices.
A radar sensor’s accuracy and its ability to support wide functionality and applications are determined initially by its resolution, which is based on two key factors: bandwidth and number of channels. The wider the bandwidth and the more channels the radar supports, the more accurate the data received. Imagine the difference between a 1990s television model and a 4K 2018 television model: As the resolution is ever improving, the sharper and more detailed is the image.
Drones as a security mechanism
Another emerging element in home security is the use of drones. An Amazon patent outlines how its unmanned aerial vehicles (UAVs) could perform a surveillance action at a property of an authorized party. It would be “hired” to look out for open garage doors, broken windows, graffiti, or even a fire. The drone would only view authorized locations and provide information back to the homeowner. The idea is to deploy Amazon’s previously proposed (but not yet realized) “delivery drone” to provide surveillance of customers’ homes between making deliveries.
In a “surveillance as a service” scenario, Amazon’s customers would pay for visits on an hourly, daily or weekly basis. Drones would be equipped with night vision and microphones to expand their sensing capabilities.
