Instead of a physical camera unit at your door, it relies on a QR code sticker and the smartphones of both the visitor and the homeowner.

Here's a breakdown of its features, how NekInsan Wireless Video Doorbell works, and what makes it stand out:

How it Works:

1. QR Code Sticker: You place a weather-resistant QR code sticker near your door.
    
2. Visitor Scans: When a visitor arrives, they scan this QR code using the NekInsan app or any standard QR code scanner (like Google Pay or Paytm) on their smartphone.
    
3. Communication Initiation:
   • With Internet (Homeowner): If your smartphone has an internet connection, scanning the QR code initiates a video call to your NekInsan app. You can see the visitor, but your phone's camera remains off by default for privacy, unless you choose to turn it on.
      
   • Without Internet (Homeowner): If your phone is offline, the system automatically switches to an audio call through a virtual number, ensuring your actual phone number remains confidential.
      
   • No Smartphone/Internet (Visitor): If the visitor doesn't have a smartphone or internet, the sticker also displays a helpline number they can call. This connects them to you via an IVR (Interactive Voice Response) system, again using a virtual number to protect your privacy.
      
4. Real-time Interaction: You can communicate with the visitor in real-time through audio or video calls, even if you're not at home.

Key Features & 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: No wiring, no complex hardware, no electricity 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. A pack of two "Smart Doorbell" stickers is listed at ₹699 on their website.
   
• 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: Includes an SOS feature within the app to quickly contact emergency services or pre-designated contacts.
   
• Remote Communication: Answer your "doorbell" from anywhere with your smartphone.
   
• "Made in India" Product: NekInsan is an Indian company.
   
• Relies on Visitor's Smartphone: The visitor needs a smartphone and either the NekInsan app or a general QR code scanner to initiate a video call. While an audio call option exists for those without a smartphone, it's not the primary video communication method.
   
• Not a "Camera" Doorbell: It's important to understand that it's not a doorbell with a built-in camera that's constantly monitoring your entry.

Who is it best suited for?

• Privacy-conscious individuals: If you're uncomfortable with a permanent camera feed at your door.
   
• Renters or those who want easy installation: No drilling or complex wiring required.
   
• Budget-conscious buyers: A more affordable entry point into video communication at the door.
   
• Homes with unreliable internet: The audio call fallback is a plus.
   
• People looking for a simple video/audio communication solution: Without the need for advanced security monitoring features like motion detection.

NekInsan Wireless Video Doorbell offers a unique, privacy-centric, and highly accessible approach to home communication. It's a great option if its specific features align with your needs, particularly if ease of installation, affordability, and privacy are your top priorities over traditional surveillance features like continuous motion detection.
