Video Surveillance as a Service (VSaaS) is cloud-hosted surveillance sold as a subscription. Instead of buying and running your own VMS servers, cameras (or a small on-site bridge) connect to a provider's cloud, which records the video, runs analytics, and serves live and recorded footage to a browser or app. The provider owns the infrastructure, updates, and uptime; the customer pays per camera per month.
The appeal is the cost shape and the operations. VSaaS turns a large up-front CapEx (servers, storage, integration) into a predictable OpEx subscription, and it removes server maintenance, patching, and capacity planning from the customer's plate. Most serious VSaaS uses a hybrid pattern: a local bridge or smart camera buffers full-resolution video on the edge and uploads thumbnails, metadata, and clips on demand — Verkada and Eagle Eye Networks work this way — cutting sustained upload to as little as tens of kbps per camera.
The pitfalls are bandwidth and data control. Continuous full-resolution upload can exceed a site's outbound link, which is why the edge-buffer pattern exists; cloud egress and retrieval fees can surprise; and where the footage physically lives raises data-residency and cross-border questions (GDPR Chapter V) that an on-prem system never faces.

Fora Soft Video Engineering Handbook
VSaaS moves recording and management to the cloud, which trades server rooms for a monthly bill driven by upstream bandwidth and egress. Our seven-volume handbook covers the full video stack, and for VSaaS start with Volume 3, which covers CDN and caching, players for browser and mobile viewing, QoE monitoring and the economics of delivering video from the cloud. Written by Nikolay Sapunov, CEO at Fora Soft.
