Step-by-step guide to migrating from traditional NVR/DVR hardware to a modern cloud VMS, covering camera compatibility, network preparation, data migration, and cost savings analysis.
Traditional NVR (Network Video Recorder) and DVR (Digital Video Recorder) appliances served the industry well for two decades, but their architectural limitations are increasingly apparent. Fixed storage capacity forces hardware upgrades every 3-5 years. Adding cameras requires purchasing new NVR units. Remote access often requires VPN configuration and port forwarding that creates security vulnerabilities.
Cloud VMS eliminates these constraints. Storage scales elastically, new cameras connect through software configuration, remote access works through encrypted web connections, and AI analytics run without additional hardware. For organizations managing multiple sites, the operational simplification alone justifies the migration.
The first step is auditing your existing cameras. Document each camera's manufacturer, model, firmware version, ONVIF support, and current resolution/frame-rate settings. Any ONVIF-compatible camera can connect to Visylix without replacement.
Most IP cameras manufactured in the last 10 years support ONVIF Profile S (streaming) and often Profile G (recording) and Profile T (advanced streaming). If some cameras lack ONVIF support, Visylix also supports direct RTSP connection using camera-specific URLs.
Cloud VMS requires sufficient upload bandwidth to stream video from cameras to the cloud. As a rule of thumb, budget 2-4 Mbps per camera at 1080p or 6-10 Mbps per camera at 4K. For a 50-camera site at 1080p, you need approximately 100-200 Mbps of dedicated upload bandwidth.
Alternatively, a hybrid deployment uses on-site edge processing to reduce bandwidth requirements by 60-80%. Only metadata, AI detections, and event clips are uploaded to the cloud, while full-resolution recordings remain on local storage.
Run the cloud VMS in parallel with your existing NVR for 2-4 weeks. This ensures all cameras connect reliably, recordings are properly retained, and operators are comfortable with the new interface before decommissioning the NVR.
Visylix supports gradual migration: start with a subset of cameras, validate performance, then add remaining cameras in phases. The free 7-day trial lets you test with your actual camera infrastructure before committing to a paid plan.
A typical 50-camera NVR deployment costs $15,000-25,000 in hardware (NVR units + hard drives), plus $3,000-5,000 in annual maintenance and replacement drives. Hardware refresh every 4-5 years adds another $10,000-15,000. Over 5 years, total on-premise cost: $30,000-55,000.
The same deployment on Visylix Cloud costs $49-99/month ($588-1,188/year) for Starter-Pro plans. Over 5 years: $2,940-5,940. Even adding bandwidth costs, the cloud approach typically saves 60-80% over traditional NVR, while gaining AI analytics, remote access, and automatic updates.
