For many years, organizations have relied on legacy TV Network Protocol (TVNP) to share CCTV systems, primarily designed for analogue CCTV signals. However, the landscape of surveillance technology is evolving, and Digital Video Network Protocol (DVNP) is now at the forefront. DVNP supports IP-based CCTV system interoperability, providing a modern solution for sharing surveillance access efficiently and securely.
Understanding DVNP and TVNP: A Comparison
TVNP was originally developed by Transport for London (TfL) to facilitate CCTV sharing among the Metropolitan Police, Highways England, and TfL control rooms. While TVNP has been widely used, it is limited to sharing analogue footage.
The emergence of IP cameras and initiatives like the Open Network Video Interface Forum (ONVIF) have significantly improved digital video standardization, paving the way for a protocol that supports digital CCTV sharing. This advancement led to the creation of DVNP, a protocol designed to meet the demands of modern surveillance systems.
The Necessity of DVNP
Open architecture protocols, like DVNP, enable different technologies to communicate, regardless of the manufacturer. This flexibility allows organizations to integrate legacy equipment with new technology seamlessly, even if the devices are from different manufacturers. More importantly, it facilitates integration with external systems.
Organizations often need to share CCTV streams and allow limited control over cameras without granting full access to their entire security infrastructure. DVNP addresses this need, enabling organizations to collaborate more effectively to enhance public safety and security.
How DVNP Works
In DVNP, the organization sharing its CCTV is referred to as the broadcaster. The broadcaster can share video streams or both video streams and camera controls with the receiving system. They also have the flexibility to choose which cameras to share and for how long. For enhanced collaboration, an organization can simultaneously broadcast and receive footage.
Benefits of DVNP
DVNP is scalable, secure, and cost-effective. Broadcasters can share numerous cameras with stakeholders’ systems, as long as they have sufficient bandwidth. This scalability and flexibility make DVNP a superior choice compared to previous network protocols.
Real-World Application of DVNP
A notable implementation of DVNP was during the 2022 Commonwealth Games, where DVNP was used to allow the traffic-focused surveillance team to access live footage from approximately 450 cameras operated by Highways England, ensuring critical routes for events and incoming visitors were closely monitored as part of broader event management.
Inter-agency collaboration is crucial for major event security, and DVNP facilitates this collaboration. This technology brought together video streams from various disparate systems, providing the tools and framework needed to ensure the safety of millions of participants and spectators.
