Leveraging 4 NVRs Instead of Decoders to Create an Efficient Multi-Screen IP Surveillance System

Introduction: In modern security surveillance systems, a multi-screen IP monitoring setup serves as both a potent security management tool and a key driver of operational efficiency. This article will delve into the strategic utilization of 4 Network Video Recorders (NVRs) as a substitute for conventional decoders, allowing for the construction of an efficient, stable, and multi-screen IP surveillance system that delivers clear monitoring visuals and seamless user experience.

How to use 4 NVRs instead of decoders to form a multi-screen IP monitoring system


1. Why Opt for NVRs?

Traditional multi-screen surveillance systems often employ decoders to decode compressed video streams into visible images, which are then displayed across multiple monitors. However, decoders may be constrained by performance and flexibility, potentially falling short in meeting complex surveillance demands. Conversely, utilizing NVRs as core components can capitalize on their high performance, multi-channel capacity, and network scalability, unlocking greater potential for multi-screen IP surveillance systems.

2. Building the Multi-Screen IP Surveillance System

Step 1: Allocating NVR FunctionsDesignate a 64-channel NVR as the central control unit responsible for centralized management and storage of video streams from all cameras. The additional 16-channel and 24-channel NVRs can then be connected to the respective number of cameras as per requirements.

Step 2: Optimizing Network ArchitectureHarness three 24-port switches to establish connections between all NVRs and cameras, ensuring stable network transmission and efficient video stream distribution.

Step 3: Flexible Monitor LayoutLeverage the 100-inch main monitor as a surveillance wall, catering to real-time display of visuals from all cameras for rapid multi-screen viewing. Meanwhile, the four 40-inch monitors can be used to showcase visuals from specific zones, enabling localized surveillance.

3. Gained Advantages

High-Performance Decoding: Optimized NVRs deliver efficient decoding prowess, facilitating swift decoding and seamless display of multiple video streams.

Flexible Layouts: NVRs support multi-channel display and layout configurations, enabling users to customize multi-screen visuals to suit specific needs.

Stability and Redundancy: The multi-NVR configuration offers redundancy backups, reducing the risk of single-point failures and ensuring system stability.

Network Management: NVRs centrally manage and store video streams, simplifying system maintenance and data backups.


Strategically utilizing 4 NVRs in lieu of conventional decoders empowers the creation of an efficient and stable multi-screen IP surveillance system. Beyond delivering high-performance decoding capabilities, this approach allows users to tailor display layouts across various monitors to accommodate diverse surveillance scenarios.
