In recent video security environments, NVR equipment is not simply configured as a local network,
and users should be able to access their NVRs from anywhere in the world via the public network (internet) to view real-time images and retrieve recorded data.
Woohyun Digital's server solution is the fastest and most reliable integrated connectivity platform that connects users and
NVR equipment beyond the limitations of complex network environments and firewalls,
providing stable services through a hybrid architecture that combines P2P and relay technology.
NVRs in a typical home or enterprise environment are located on private networks at the bottom of the router (NAT) and are blocked from external access.
Complex port forwarding or DDNS settings were required to address this, but this can be a difficult and security vulnerability for the general user.
Woohyun Digital's server solution solves all of these complexities at the server end. As long as the equipment is connected to the Internet,
our server automatically finds the best path and forms a secure tunnel with your app or VMS.
Anytime, Anywhere, Seamless Connection:
Users can immediately access the NVR as if they were in the field without complex network settings
Our server solution is an organic system that consists of three complementary core server groups to ensure stable service in any network situation.
Role: A matchmaker that finds the fastest 'direct path' between the user and the NVR.
Core technology: Using advanced NAT Traversal (hole-punching) technology, we prioritize peer-to-peer (P2P) connections where clients and
NVRs send and receive data directly without going through a server.
Advantages: It dramatically reduces server bandwidth costs and minimizes data transfer latency, providing high-definition video with excellent real-time performance.
Role: A reliable detour that ensures connectivity in strict firewall environments where P2P connectivity is not possible
Core technology: It has a high-performance streaming engine that can handle large-scale simultaneous access. In the event of a P2P connection failure, traffic is immediately diverted to the relay server to relay the image transmission.
Advantage: It guarantees a 100% success rate of connectivity in any adverse network environment (e.g., enterprise symmetric NAT, multiple firewalls).
Role: Cloud storage that overcomes NVR's physical storage limitations and securely backs up data.
Core technology: Provides high durability and scalability based on distributed file systems. It can be scaled up to a Video Surveillance as a Service (VSaaS) model that backs up NVR's critical event footage in real time to the cloud or records it directly to the cloud without NVR.
Advantage: sensitive data is securely preserved in the event of equipment theft or damage, and storage capacity can expand indefinitely as needed.
With intelligent P2P technology and a powerful hybrid connection of relay servers,
it provides 99.99% service availability without failure in any network environment worldwide.
P2P processes most of the traffic, lowering server operating costs and providing users with high-definition video without delay.
The relay server maximizes efficiency by intervening only when it is absolutely necessary.
It's not just a connection. All connection sections (via P2P and Relay) are secured by standard encryption
protocols such as AES-256 to prevent leakage or interception of image data.
Our server architecture is designed to accommodate multiple equipment and concurrent users. Cloud-native,
flexible scaling allows you to scale your infrastructure as your business grows.
Easy retrieval of network connection settings using QR code
Client Viewer attempts 4 connection methods using information in the QR code
based on uPnP, DDNS Server, Stun Server, and Relay Server technologies
1st: Scans the LAN to find and connect to the NVR
2nd: Attempts to connect the NVR via the Internet using uPnP and DDNS server
3rd: Attempting to connect the NVR using the Stun server of P2P Servers(Tunneling)
4th: Establishing the connection through the Relay Server of P2P Servers (Relaying)
Woohyun Digital's server solution is not just an additional feature of NVR, it is a powerful network infrastructure
that transcends the physical constraints of hardware and the spatial constraints of users.
With this server solution perfectly combined with our NVR equipment, customers will always experience reliable and
fast video security services without having to worry about complex network technologies.
