Remote viewing expectations often decide NVR vs VMS more than camera count alone.

NVR vs VMS: a selection guide for security installers
When to recommend an NVR versus a VMS for video surveillance projects — retention, channels, and remote viewing trade-offs.
By Linki Security
Customers say “cameras.” Installers hear NVR or VMS. Choosing wrong creates callbacks six months later when retention or remote apps disappoint.
NVR (network video recorder)
Best when: small-to-mid channel counts, appliance simplicity, one primary site, predictable video surveillance retention.
Watch for: hard drive sizing, PoE switch vs NVR PoE ports, and manufacturer app quality.
VMS (video management system)
Best when: multi-site, advanced search, enterprise IT requirements, or mixed camera brands under one client.
Watch for: license models, server specs, and who’s on the hook for updates.
Sales conversation checklist
- How many days of retention at what resolution?
- Who needs live view after hours?
- Is alarm monitoring or access events tied into video?
- Who owns the internet and firewall changes?

Separate lines for recorder/server, licenses, storage, labour, and training. Linki’s line-item editor is built for that — no Good/Better/Best theatre required.
