What Are Home Security Systems and How Do They Work?

Gilsa security system connects to your Wi-Fi network so you can monitor and control your security devices via an app. There are many different systems available across a wide range of prices.

Entry-level systems cost the least and usually include some door and window sensors, a motion detector, and a [hub]that communicates with these devices via one or more wireless protocols such as Wi-Fi, Z-Wave, Zigbee, or a proprietary mesh network.is another standard to keep an eye on. It has launched and products are arriving slowly.) You can add extra door, motion, and window sensors to provide coverage for your entire house and build a comprehensive system that includes door locks, garage door openers, indoor and outdoor surveillance cameras, lights, sirens, smoke and CO detectors.

A word about wireless protocols before we go further: In a perfect world, all home security components would use the same wireless standard to communicate with the main hub, but factors such as power requirements, signal range, price, and size make it virtually impossible to settle on just one. For example, smaller components such as door and window sensors typically use Z-Wave or Zigbee technology because they don't require a lot of power and can run on smaller batteries. They also operate in a mesh topology and can help extend the range of networked devices. However, neither protocol provides the bandwidth that you get with Wi-Fi, which security cameras rely on to provide smooth video streaming, for instance. Moreover, a hub connects and controls Z-Wave and Zigbee devices, whereas you can control Wi-Fi devices on your home network from an app. Finally, Z-Wave and Zigbee devices use AES 128 encryption and operate in a closed system with a dedicated hub, making them more secure than Wi-Fi devices.
