How Does the Ezviz Home Camera Ensure Secure Remote Access Without Port Forwarding?

I recently installed an Ezviz home camera on my Wi-Fi network, which raised the question: How is it possible to access my home camera without using port forward?

Firewall Functionality

Firewalls function as a barrier, controlling and monitoring network traffic to prevent unauthorized access from external sources without impeding internal traffic.

It's like having a lock on a house's front door; while a key is required to enter, individuals inside can simply turn the thumb latch and exit.

In the context of the home camera, it can communicate with an external server owned by the camera company to transmit footage for remote viewing through the Ezviz app.

No Port Forwarding Needed

While standard port forwarding involves providing access keys to specific doors, the Ezviz camera operates differently.

It functions more like agreeing to meet a friend at a coffee shop - a rendezvous point that doesn’t require the friend to have a key.

Instead of direct access through port forwarding, it establishes a secure connection with an external server to share footage through a prearranged location, bypassing the need for port forwarding.

Secure Remote Access

By leveraging this approach, the camera maintains security by avoiding port forwarding, which can potentially expose the network to vulnerabilities.

With this method, remote access to the camera is possible without compromising network security.

Conclusion

Understanding the inner workings of firewalls, external servers, and secure communication methods sheds light on this innovative approach, enabling seamless remote access to devices such as Ezviz home cameras while ensuring network protection.
