In a smart home security setting, the terms ‘hub’ and ‘keypad’ are sometimes used interchangeably. It is understandable given the fact that a lot of keypads double as hubs. But then you might run across something like Vivint’s HomeProtect package. HomeProtect comes with both a hub and a keypad. So what is the difference?
Some home security manufacturers combine all the functions of the security hub and keypad into a single device. But others, like Vivint, utilize separate devices. The reason is simple: the line between home automation and home security is nearly nonexistent at this point. Separate devices make it easier to manage more complex home automation systems featuring both convenience and security devices.
A Hub Is the Brain
Modern home automation and security systems are incredibly complex thanks to all the devices customers have access to. Even the devices themselves can be fairly complicated. Just think of a home security camera featuring motion detection, infrared night vision, onboard audio, and the ability to distinguish between humans and animals. All those features require digital management.
This is where the security hub becomes important. A hub acts like a system’s brain. Although designs can vary from one manufacturer to another, a typical hub:
- Manages Communication – The hub’s primary purpose is to manage communication between devices. Every camera, sensor, etc. connects to the hub centrally. The hub also communicates with the system’s mobile app.
- Houses Critical Components – The hub also houses critical system components. They include things like the system siren, a backup battery, and a backup cellular radio in case internet service goes out.
- Maintains a Connection – The hub is designed to maintain a continuous connection with a remote monitoring provider. That connection is encrypted for security and privacy purposes.
When companies like Vivint choose to keep the hub and keypad separate, hubs tend not to have screens or buttons. They are just boxes that sit on a shelf. They can be tucked away, out of sight, if a homeowner doesn’t want his hub to be seen.
The Keypad Is the Interface
Accessing your security system’s brain requires an interface of some sort. That is what the keypad is. In modern systems, the keypad is a wireless, battery-operated device that’s normally mounted on the wall nearest the main entryway. Users can arm and disarm the system with this keypad. The system can also access it for programming purposes.
In general terms, the keypad:
- Arms and Disarms – The keypad is designed for quick action at the door. Arming and disarming is as easy as entering a PIN code.
- Displays System Status – The keypad’s screen provides visual access to system status. Individual device status can usually be observed by pushing a button or tapping the screen.
- Facilitates Programming – For more complex systems that allow automation, the keypad is the device used for programming. But programming is typically easier with a mobile app.
- Has a Panic Button – Some modern keypads are equipped with a panic button. In the event of an emergency, getting help is as easy as pushing it. Remote monitoring personnel immediately receive an alert. They spring into action on your behalf.
In the case of Vivint’s HomeProtect package, customers also get a mobile app with full system control. This is a big deal for the simple fact that programming tends to be easier on a phone than a wall-mounted keypad.
In closing, remember that this post assumes you’re working with a home security system that separates functions into distinct hub and keypad devices. There are manufacturers who still prefer to combine functions in a single device.
