Difference between Wireless Video Doorbell and Nekinsan QR Code Wireless Video Doorbell

Here's a breakdown:

Wireless Video Doorbell (Standard):

• Visitor Interaction: Typically involves a physical button that visitors press. This action then triggers the doorbell to ring and sends a notification to the homeowner's smartphone or a connected chime.
   
• Communication: Homeowners usually communicate with visitors through a built-in camera, microphone, and speaker in the doorbell unit itself via a smartphone app.
   
• Installation: Requires mounting the doorbell unit near the door and connecting it to a Wi-Fi network. Some models are battery-powered, while others may require wiring.
   
• Power: Can be battery-powered (rechargeable or replaceable) or wired into existing doorbell wiring.
   
• Connectivity: Relies on a Wi-Fi connection for transmitting video and audio, and for sending notifications.
   
• Features: Often includes features like motion detection, night vision, two-way talk, video recording, and integration with smart home systems.

Nekinsan QR Code Wireless Video Doorbell:

• Visitor Interaction: Visitors scan a QR code sticker placed near the door using the Nekinsan app or any standard QR code scanner on their smartphone (like Paytm or Google Pay).
   
• Communication:
  • With Internet: Scanning the QR code initiates a video call to the homeowner's smartphone via the Nekinsan app. The homeowner can see the visitor (their own camera remains off unless they turn it on) and speak with them.
     
  • Without Internet: The system automatically switches to an audio call, connecting through a virtual number to protect the homeowner's privacy.
     
  • No Smartphone/Internet: Visitors can call a helpline number displayed on the sticker to connect with the homeowner via an IVR system through a virtual number.
     
• Installation: Very simple, involving just sticking the QR code sticker near the door. No wiring or complex setup is needed.
   
• Power: Requires no electricity or batteries as it leverages the visitor's and homeowner's smartphones.
   
• Connectivity: Relies on the internet/mobile data connection of both the visitor's and homeowner's smartphones for video calls. Audio calls can be made even without internet via a virtual number.
   
• Features:
  • No built-in camera on the doorbell unit itself. The visitor's smartphone camera is used for video calls.
  • Provides a scanning history with visitor photos (captured when they scan), date, time, and location (via GPS).
  • Offers a "call back" button for easy follow-up.
  • Ensures 100% data privacy for the homeowner by using virtual numbers and not revealing their personal contact details.
  • Includes an SOS emergency calling feature.

In essence, the standard wireless video doorbell uses dedicated hardware at the door for communication, while the Nekinsan system cleverly utilizes QR code technology and the smartphones of both the visitor and the homeowner to achieve a wire-free, installation-free communication method with a strong emphasis on privacy.
