It's crucial to understand that it is not a traditional doorbell with a built-in camera mounted at your door. Instead, it leverages QR code technology and the smartphones of both the visitor and the homeowner to facilitate video (and audio) communication.

Here's a breakdown of how the Nekinsan Wireless Video Doorbell works:

1. The "Doorbell" Unit (QR Code Sticker):

• No Physical Camera: The core of the Nekinsan system is not a traditional doorbell with a built-in camera. Instead, it's a weather-resistant QR code sticker that you place near your door or on your door frame.
   
• No Wiring, No Electricity, No Batteries: Because it's just a sticker, it requires absolutely no wiring, external power supply, or batteries. This makes installation incredibly simple – you just stick it on.

2. Visitor Interaction:

• Scanning the QR Code: When a visitor arrives, they use their smartphone to scan the QR code on the sticker. They can use the dedicated Nekinsan app or any standard QR code scanner app (like Google Pay, Paytm, or Google Lens).
   
• Visitor's Smartphone Camera: The video stream (if a video call is initiated) originates from the visitor's smartphone camera, not a fixed camera at your door.

3. Homeowner Communication (via Nekinsan App):

The system then attempts to connect with the homeowner's smartphone based on their internet availability:

• With Internet (Homeowner):
  • If your smartphone has an internet connection, scanning the QR code initiates a video call to your Nekinsan app.
  • You will be able to see the visitor through their phone's camera.
  • Crucially, for privacy, your own phone's camera remains off by default during this call, unless you choose to manually turn it on.
  • You can communicate with the visitor in real-time using two-way audio.
     
• Without Internet (Homeowner):
  • If your phone is offline or has no internet connection, the system automatically switches to an audio call.
  • This audio call is connected through a virtual number, ensuring that your actual phone number remains confidential and private.
     
• No Smartphone/Internet (Visitor):
  • For visitors who do not have a smartphone or internet access, the Nekinsan sticker also displays a helpline number.
  • They can call this number, and the system will connect them to the homeowner via an IVR (Interactive Voice Response) system, again using a virtual number to maintain privacy.

4. Key Features and Advantages:

• Privacy-Focused: This is a major differentiator. Since there's no continuous camera feed at your door, and your phone number is masked with virtual numbers, your privacy is highly protected.
   
• Extremely Easy Installation: As mentioned, no wiring, complex hardware, or electricity is needed for the "doorbell" unit itself. You simply stick the QR code. This makes it ideal for renters or anyone who wants a hassle-free setup.
   
• Cost-Effective: Generally much more affordable than traditional video doorbells, as it leverages existing smartphone technology.
   
• Works Without Home Internet (for audio calls): This is a significant advantage in areas with unreliable internet, as visitors can still connect via audio calls.
   
• Visitor Logging: The app logs interactions, including a photo of the visitor (captured when they scan the QR), date, time, and location (using GPS).
   
• Emergency Helpline & SOS: As discussed previously, it includes an SOS feature within the app to quickly contact emergency services or pre-designated contacts.
   
• Remote Communication: You can communicate with visitors from anywhere with your smartphone.
   
• Data Security: Nekinsan emphasizes 100% data security, using call masking and ensuring personal information is secured against leakage.
   
• "Made in India" Product: Nekinsan is an Indian company.

In summary:

The Nekinsan wireless video doorbell redefines the concept of a smart doorbell by using a QR code and leveraging the visitor's and homeowner's smartphones for communication. It prioritizes simplicity, ease of installation, cost-effectiveness, and strong privacy features, making it a unique solution in the smart home market.
