Doorbell cameras work by using a combination of motion sensors, video recording, and Wi-Fi connectivity. When someone approaches your front door, the motion sensors are triggered and start recording footage. This footage is then transmitted over Wi-Fi to your smartphone, tablet, or other device. In this way, you can see who is at your door and communicate with them, even if you’re not at home. Some doorbell cameras also have features like night vision and two-way audio, allowing you to see and hear what’s happening outside your door in real-time.
Most doorbell cameras are powered by a rechargeable battery or hardwired to your existing doorbell wiring. When the doorbell is pressed, the camera is activated and sends an alert to your device. You can then see who is at the door, talk to them through the app, and even unlock the door if you have a smart lock installed. Doorbell cameras are a great way to enhance your home security and provide peace of mind, whether you’re at home or away.
