Doorbell Cameras Wireless doorbell cameras can be considered as one of the most popular home security devices during the past several years. A doorbell camera refers to a WiFienabled doorbell that is equipped with a camera that enables you to monitor and interact with visitors through a smartphone application. If somebody is ringing your bell or even approaching your front door, the camera will alert you and you will be able to see, hear and even talk to the person at the door regardless of your location.
The use of doorbell cameras as security and convenience features in homes has continued to gain popularity. These enable you to know who is at your door without necessarily having to be around to knock on the door and check. This gives a sense of security and ensures that one can identify the visitor before allowing him/her into the compound. Some of the doorbell cameras also come with motion detection and you will be alerted when there is movement close to your front door even without ringing the bell.
All About The Doorbell Cameras Doorbell cameras are integrated with digital video and audio technology, motion sensors, wireless connectivity, and smartphone compatibility. Here is a breakdown of the key components and how they work together:
Camera and Audio The primary purpose of any doorbell camera is to capture video and audio feed from the front door. It includes a high-definition digital video camera to get a clear picture of the event. It also has a microphone to capture any sound within the vicinity and speakers for you to be able to interact with the visitors.
The live audio and video stream is then accessed using the doorbell company app on your smartphone, tablet, or computer when the doorbell button is pressed or motion is detected. You observe the visitors in the same manner as viewing them through a periscope or talking to them through a loudspeaker.
Wireless Connectivity Many doorbell cameras use Wi-Fi to stream video and audio feeds from the front door of your house. This means that you can view the camera feed from anywhere you have an internet connection on your mobile device or computer.
The doorbell camera requires a wired connection for power, which means that it will have to be connected to the doorbell wiring. As a result, there is no need to perform complex rewiring in your home when installing these cables. The only wiring required is connecting between the doorbell button and the chime. The remaining part of the system is wireless.
Smartphone Connectivity and Alerts Doorbell cameras are smart home accessories. This means they are mainly managed via a smartphone application from the camera company that owns the camera. The live feed is available through the app, or you can set the camera to notify you when motion is detected.
For instance, if someone rings the doorbell or moves close to the camera after pressing a button, the application will send an instant alert to your smartphone. This enables you to open the app at whatever time you feel convenient and witness and communicate with the visitors at your door in real time.
Cloud Storage and Video Recording Recorded videos from the camera are stored in a cloud server away from the physical location of the car. When motion is sensed or the doorbell is pressed, it will record a video clip and store it in the cloud for later review. Most systems offer between 24-72 hours of cloud video storage for free. Additionally, for the extended video streaming and recording history, there is often an offer to sign up for the video recording service.
Night Vision If not all, most of the doorbell cameras out there support night vision since they contain infrared LEDs. This enables a good video output in zero or minimal light conditions as is the case at night. They are positioning infrared LED lights across the lens of the camera that is integrated into the apparatus. These LEDs emit infrared light which is not perceptible to the human eye. However, the camera sensor can recognize this light and then light up the scene and recognize people and objects in the dark. Night vision ranges from 5-25 feet enabling you to see who is at the door before opening it.
Wide-angle lens Doorbell cameras are fitted with a lens of wide-angle to ensure that they cover a large area of view. This lets you capture a wider area of the scene outside your door like packages delivered on your doorstep or activities taking place on the sidewalk at a given point in time. For instance, some doorbell cameras can have a diagonal field of vision of up to 180 degrees or even more.
Motion Detection Sensors Almost all doorbell cameras come with motion detection features such as Passive Infrared (PIR) sensors or microwave motion detectors. These detect activity and motion within the camera’s field of vision. If the sensor is activated, the camera will begin recording video and notify your linked smartphone, even when the doorbell button has not been pressed. It can also serve as a security video camera and capture any strange movement or unauthorized persons approaching your house.
Conclusion Doorbell cameras are designed to give you a visual and auditory means of seeing and hearing what is going on at your doorstep by integrating a digital camera, microphone, wireless connectivity, and a smartphone application. They enable homeowners to observe, listen, and communicate with visitors at their doors for security and convenience. Additional features such as night vision, multiple lenses, cloud storage, and motion detection offer even more surveillance capacity. As technology advances, Doorbell cameras should continue to increase in popularity as a standard home security product.
