Having a security system in place in homes these days is a must, although the investment in placing a reliable one may somehow hinder that. But if you are looking for a cheap and handy one, the DoorBot stands to ban advanced and functional one that you can seriously consider.
The DoorBot is actually a WiFi enabled door knob that comes with a built-in camera. With the DoorBot, you can easily peek at who is at the front door without getting up using your tablet or smartphone.
The camera is activated once a person would press the doorbell button. It does the trick with the aid of an app, allowing you to access the video feed after which you can unlock the door or talk to the person who is at the door.
