A video management system (VMS) is software that connects security cameras to a central platform for live monitoring, video recording, playback, and AI-powered analytics — replacing standalone DVR and NVR hardware with a scalable, software-driven alternative.
Modern security operations can involve hundreds of cameras across multiple sites, multiple alarm systems, access control readers, and third-party analytics tools. Hardware recorders handle one job. A VMS handles all of them from a single interface — and as organisations grow, it grows with them.
Every video management system performs five core functions, regardless of vendor or deployment model:
Gartner defines VMS as software that "orchestrates a surveillance workflow by integrating cameras, encoders, recording systems, storage infrastructure, client workstations, gateway systems and analytics software." That orchestration layer is what separates VMS from any recording device.
Three technologies. Three different answers to the same question: how do you capture and manage security camera footage?
DVR (Digital Video Recorder)
DVRs work with analogue cameras connected over coaxial cable. All processing — digitising the signal, compressing the footage, writing to disk — happens inside the box. DVRs are closed systems: they only work with compatible analogue cameras and have no meaningful integration capabilities. They are legacy technology, still installed in older sites but no longer specified for new deployments.
NVR (Network Video Recorder)
NVRs work with IP cameras connected over Ethernet. They are simpler to install than VMS and require no dedicated server, but their functionality is fixed to what the hardware supports. There is no analytics layer, no multi-site management, and no open integration ecosystem. An NVR is a self-contained recording appliance — reliable, but limited.
VMS (Video Management System)
VMS is software running on a server or in the cloud. It supports any IP camera that uses standard protocols (ONVIF, RTSP, HTTP), scales from a handful of cameras to thousands across multiple sites, and provides a full analytics and integration layer on top of recording. A VMS can also manage NVRs as edge recording devices — so the two are not mutually exclusive.
If you are specifying a new security system — or planning an upgrade — VMS is the correct architecture. The only question is which VMS, and how it's deployed.
For organisations that have existing NVR hardware, Wavestore's on-premise NVR range integrates directly with WaveView, so legacy edge recording infrastructure does not need to be replaced on day one.
Not all VMS platforms are equal. The most significant architectural decision you will make when selecting a VMS is whether it is open platform or closed.
Closed VMS platforms require proprietary hardware — typically cameras from the same manufacturer. They are simpler to deploy in a single-vendor environment, but they create lock-in: you cannot add cameras from another brand without the VMS vendor's approval, you cannot switch analytics providers without replacing the platform, and you are entirely dependent on a single roadmap. If that vendor raises prices, discontinues a product, or exits the market, your options are limited.
Open platform VMS is built on published APIs and industry-standard protocols — ONVIF for cameras, open SDKs for analytics, documented integration interfaces for third-party systems. Any camera from any manufacturer that supports ONVIF will work. Any analytics engine with an open API can be connected. You choose the hardware. You choose the analytics. You choose when and how to evolve the system.
Milestone Systems — one of the largest VMS vendors in the world — acknowledges that open-platform VMS "can integrate with a wide range of cameras, sensors and third-party analytics" and helps organisations "cut down on start-up costs by letting you keep most — if not all — of your existing hardware." The industry's own consensus is that open platform is the right long-term architecture.
Wavestore is an open-platform VMS. WaveView integrates with over 6,000 camera models and connects natively to third-party technologies including access control systems, radar, perimeter intrusion detection sensors (PIDS), facial recognition engines, and AI analytics platforms — all managed from one interface. Organisations do not need to replace existing camera infrastructure to deploy Wavestore; they can add cameras from any ONVIF-compliant manufacturer as they expand.
For government and critical infrastructure buyers with US federal supply chain requirements, Wavestore is also NDAA-compliant — a standard that rules out cameras and components from a defined list of prohibited manufacturers. Many closed-platform VMS solutions built around specific hardware cannot meet this standard.

Not every VMS is built the same. When evaluating platforms, these are the criteria that separate capable systems from genuinely enterprise-grade ones.
Camera compatibility
Check the device integration library, not just the claim. How many camera manufacturers are officially supported? Does ONVIF support extend to full feature sets — PTZ control, audio, metadata — or just basic video streams? Wavestore supports over 6,000 camera models with full feature integration.
Scalability
A VMS should handle five cameras and five hundred on the same architecture, without requiring a different product tier or a system rebuild. Multi-site management — a single interface for cameras across multiple premises — is a baseline requirement for any organisation with more than one location.
Video analytics
Look for native analytics capabilities: motion detection and zone-based alerts are table stakes. Enterprise deployments will need object classification (person, vehicle, animal), behavioural detection (loitering, running, crowd density), licence plate recognition, and facial recognition. Confirm whether analytics are included in the platform licence or sold separately, and whether they run on the server or require edge hardware.
Deployment model
On-premise, cloud, or hybrid — and whether you can evolve between them without replacing the platform. Organisations with strict data residency requirements or unreliable connectivity will need on-premise or hybrid options. Confirm where video is processed and stored, and what the disaster recovery model is.
Cybersecurity
Encryption in transit and at rest, role-based access control, multi-factor authentication, tamper-proof audit logs, and a clearly communicated patching cadence. Surveillance systems are critical infrastructure — ask vendors how quickly they respond to CVEs.
Licensing model
This is where vendors diverge significantly. Some charge a base server licence, per-camera fees, and additional charges per client workstation. Others bundle these differently. Wavestore uses a per-camera perpetual licence with no base licence fee and no charge for additional client workstations — operators can be added without additional cost. Understand the total cost of ownership, not just the headline price.
Integration ecosystem
Access control, intruder alarm panels, PIDS sensors, radar, body-worn video, POS systems — a VMS that can only integrate with cameras has a ceiling. Ask specifically about the integrations you need today and the ones you are likely to need in three years.
Support and channel model
Whether a vendor sells direct or through an integration channel matters for how quickly issues get resolved. Understand who holds the support relationship, what the SLA covers, and what the vendor's product roadmap looks like.
Where your VMS runs has real implications for resilience, data sovereignty, cost structure, and long-term flexibility. There is no universally correct answer — the right deployment model depends on your organisation's specific infrastructure, compliance requirements, and operational priorities.
On-premise VMS
The software runs on servers at your facility. Video is recorded and stored locally, processed locally, and accessed locally. You control the hardware, the storage capacity, and the data. On-premise is the right choice for organisations with strict data residency requirements (healthcare, government, regulated financial services), sites with unreliable internet connectivity, or security policies that prohibit video transmission outside the organisation's network.
The trade-off is operational responsibility: your IT team manages the hardware, handles storage upgrades, and applies software patches. On-premise VMS is not a set-and-forget deployment.Wavestore's WaveView is an on-premise VMS, available as software for your own server infrastructure or as a pre-configured appliance via Wavestore's NVR hardware range.
Cloud VMS
The software and storage run on infrastructure managed by the VMS provider. Cameras stream video to the cloud over an internet connection; operators access footage through a web browser or mobile app from anywhere. There is no server to maintain, no storage to provision, and no software patches to apply manually.
Cloud VMS suits organisations that want to eliminate hardware management, prioritise anywhere-access, or manage large numbers of geographically dispersed cameras without a dedicated IT team at each site. The trade-off is a dependency on internet connectivity — if your connection fails, remote access to live footage is interrupted, though most systems continue recording locally and sync when connectivity is restored.
Hybrid VMS
Hybrid architectures combine local recording at the edge with cloud management and analytics. Each site records continuously to local storage, providing resilience against connectivity failures. The cloud layer provides unified management across all sites, advanced analytics processing, and centralised access from anywhere.
Hybrid is increasingly the default architecture for enterprise and multi-site deployments. Local edge recording ensures each site operates independently; cloud components provide the intelligence and visibility layer across the entire estate.
WaveFusion is Wavestore's unified cloud-native platform, designed for organisations managing complex multi-site security infrastructure. It brings cameras, access control, analytics, and operational data into a single interface — with the flexibility to integrate existing on-premise systems rather than requiring a rip-and-replace migration.
Buyers who choose an open-platform VMS are not locked into a single deployment model. As organisational requirements evolve, the platform can evolve with them.
Video management systems are not sector-specific — but the integrations, analytics, and compliance requirements that matter vary significantly depending on where you operate.
Critical infrastructure
Power stations, water treatment facilities, transport hubs, and data centres operate in environments where 24/7 uptime is not optional and perimeter security failures have consequences beyond financial loss. VMS in these environments integrates with radar and PIDS sensors for wide-area perimeter detection, uses slew-to-cue PTZ automation to point cameras at detected threats automatically, and must meet NDAA compliance requirements for any US government-adjacent supply chain.
Retail
Retail deployments use VMS analytics for people counting and footfall tracking, queue management, loss prevention, and POS transaction correlation. A customer loitering in a specific zone for longer than a defined threshold triggers an alert — without an operator having to watch every feed manually.
Education
Campus-wide camera management, access control integration for building entry events, and safeguarding workflows — VMS in education environments typically spans multiple buildings with centralised oversight and individual site autonomy.
Warehousing and logistics
Perimeter security at large sites, yard management (vehicle tracking, loading bay occupancy), and operational analytics across shifts. Integration with access control and gate automation is common.
Ports and maritime
Wide-area surveillance in challenging environments — VMS here integrates with radar, AIS vessel tracking, and slew-to-cue PTZ systems to cover large bodies of water and coastline that no fixed-camera grid could monitor effectively.
Banking and finance
The banking and finance sector demands audit-quality evidence management, tamper-proof footage retention for regulatory compliance, and integration between ATM events and camera feeds.
Government and public safety
Body-worn video integration, evidence chain-of-custody management, NDAA compliance for federal supply chain requirements, and integration with command and control platforms.
What is the difference between VMS and CCTV?
CCTV refers to the camera hardware and the physical surveillance network — the lenses, cables, and recording devices that capture footage. A VMS is the software layer that connects to and manages those cameras. It handles recording, playback, analytics, alerts, and system management. You can have CCTV without VMS (using standalone recorders), but you cannot deploy a VMS without a camera network to connect it to.
Does a VMS need special cameras?
No. Open-platform VMS platforms support any IP camera that uses ONVIF, the industry-standard protocol for network video devices. Wavestore integrates with over 6,000 camera models from hundreds of manufacturers. The only requirement is that the camera supports IP connectivity and a standard protocol — proprietary hardware is not needed.
What is an open-platform VMS?
An open-platform VMS uses published APIs and supports industry-standard protocols — ONVIF for cameras, open SDKs for analytics, documented interfaces for third-party integrations. It will work with cameras, analytics engines, and security systems from any vendor. This is the opposite of a closed or proprietary VMS, which requires specific hardware and limits which third-party systems can connect.
How much storage does a VMS need?
Storage requirements depend on resolution, frame rate, compression codec, and how long footage must be retained. As a general guide: a 1080p camera recording continuously consumes approximately 1–2 TB per month. A 4K camera requires 3–4 TB per month. Retention requirements vary by sector — retail typically retains 30 days, regulated industries 90 to 365 days. Most VMS vendors provide storage calculators; Wavestore's team can size storage for your specific configuration.
Can a VMS integrate with access control?
Yes. Most enterprise VMS platforms integrate with access control systems, door controllers, and alarm panels. This enables automated workflows: a forced door entry triggers high-frame-rate recording from the nearest camera; a badge presented at an access reader is automatically correlated with video from that location; an alarm event pulls up the relevant camera feed on an operator's screen without manual intervention.
Is VMS software expensive?
Licensing models vary significantly across vendors. Some charge a base server licence, per-camera fees, and per-client-workstation fees — costs that compound as deployments grow. Wavestore uses a per-camera perpetual licence model with no base licence fee and no charge for additional client workstations. You pay for the cameras you connect, not for the number of operators who access the system. Total cost of ownership, rather than headline licence price, is the right basis for comparison.
What happens if the internet goes down?
For on-premise VMS, nothing — the system operates entirely independently of internet connectivity. For cloud or hybrid deployments, cameras typically continue recording to local edge storage during an outage; footage syncs to the cloud when connectivity is restored. Remote access to live feeds will be unavailable during the outage, but no footage is lost. Hybrid architectures are specifically designed to eliminate this dependency at the site level.
What is VMS in CCTV?
In a CCTV context, VMS is the software platform that replaces or sits above standalone digital video recorders. It connects all cameras in a CCTV network to a central management interface, adds recording control, analytics, and integration capabilities, and allows operators to manage the entire network — including multi-site deployments — from a single application.
A VMS is the software backbone of any modern security operation. Getting the architecture right at the point of selection — open platform over closed, the right deployment model for your infrastructure, a licensing structure that scales without punishing growth — determines whether the system serves you for a decade or creates a costly migration in three years.
Organisations that choose open-platform VMS protect their existing hardware investment, maintain the freedom to add the best available camera and analytics technology as it emerges, and avoid the commercial leverage that closed-platform vendors hold over customers who are locked in.
Wavestore is built on this principle. WaveView and WaveFusion are open-platform systems — camera-agnostic, integration-ready, and licensed on a per-camera basis with no hidden fees for operators or base licences.
