Which is cheaper over 5 years: cloud or on-prem cameras?

Depends on camera count and IT model. Under 50 cameras at a single site with thin IT, cloud usually wins once you include the avoided server, IT labor, and refresh hardware. At 200+ cameras with strong internal IT, on-prem usually wins because the per-camera SaaS cost compounds and the server amortizes across many cameras. Model both for your specific shape.

Can I run cloud and on-prem cameras together?

Yes, and most large enterprises do: cloud at branch offices, retail, or remote sites where IT is thin, and on-prem at headquarters or regulated facilities. The tradeoff is two dashboards. Some customers stitch them together with Genetec Security Center as the unifying VMS, or with a PSIM layer. Two panes is fine if the alternative is one pane that fits neither use case.

What about data sovereignty? Where does cloud video actually live?

Vendor-dependent. Verkada and Eagle Eye Networks operate US data centers; Avigilon Alta uses AWS; Rhombus and Spot AI also run on US cloud infrastructure. EU residents at US sites can pull GDPR scope. If your policy says video must not leave the building, on-prem (Milestone, Genetec, ExacqVision) is the answer. If your policy says US-only with documented controls, cloud usually clears it with a signed DPA and the right region.

How hard is it to switch from cloud back to on-prem (or the other way)?

Cloud-to-on-prem is harder. You replace cameras (most cloud platforms only run their own hardware), retrain IT on a real VMS, and migrate or sunset the cloud footage. Budget 60-80% of the original install cost plus a server build-out. On-prem-to-cloud is easier since cloud platforms are designed for greenfield rollout; camera replacement dominates the cost. Switch at a hardware refresh boundary.

How much WAN bandwidth do cloud cameras actually use?

Per-camera continuous upstream depends on resolution, frame rate, and motion. A 50-camera site typically wants a dedicated business internet circuit with redundant failover. Most cloud platforms do edge recording with cloud sync to mitigate spikes, so steady-state is lower than a naive calculation. Measure your existing site bandwidth before signing for a 100-camera cloud rollout. Cellular failover at scale gets expensive fast.

What retention windows are realistic on each architecture?

Cloud platforms commonly bundle 30, 60, or 90-day retention into the per-camera license, with longer retention as a paid tier. On-prem retention is bounded by your storage. A 50-camera site sized to 365 days at moderate motion needs meaningful storage but no recurring fee. PCI-DSS minimum is 90 days; HIPAA-touching healthcare is commonly 30-90 days; long investigation retention often pushes customers toward on-prem.

Cloud-managed cameras win for multi-site enterprise without per-site IT teams, fast deployment, and predictable subscription budgeting. On-prem VMS wins for regulated data-sovereignty requirements, large camera counts where SaaS economics break, and customers with strong internal IT already running servers. Most large enterprise installs are hybrid: cloud at branches, on-prem at HQ or data centers. The decision is about IT philosophy, not a specific vendor.

§01 At a glance

How to actually choose.

Pick the criterion that matters most for your sites and IT model, then read the row. This is an architecture-vs-architecture read, not a single-vendor pitch. Cloud examples: Verkada, Avigilon Alta, Eagle Eye Networks, Rhombus, Spot AI. On-prem examples: Milestone XProtect, Genetec Security Center, ExacqVision, OnSSI, Hanwha Wisenet WAVE, Axis Camera Station.

Criterion	Cloud-managed	On-prem
Total cost of ownership	Predictable annual subscription per camera. Lower Day 1 capex, higher 5-year recurring. Budget lives in opex.	Capex-heavy Day 1 (cameras, NVR/server, storage). Lower ongoing software cost; you own the hardware refresh. Budget lives in capex with smaller opex line.
IT requirements	Cameras phone home outbound. No on-prem server, no port-forwarding, no Windows box to patch. Lean IT signs off fast.	Server hardware, OS patching, VMS upgrades, storage expansion, backups. Assumes a working internal IT team or a managed-service contract.
Data sovereignty	Footage lives in the vendor cloud (regions vary). Sovereignty depends on the vendor signing the right paperwork (BAA, DPA, FedRAMP).	Footage stays on your network and storage. You control where it lives, who can touch it, and how long it stays.
Network bandwidth	Steady upstream bandwidth per camera (varies by resolution and motion). 50-camera site can sustain meaningful sustained upload. Cellular failover gets expensive.	Local recording. Almost no WAN bandwidth needed for storage. Remote viewing is the only real WAN demand.
Failure modes	A vendor cloud outage or site internet outage takes the dashboard down (most platforms keep edge recording for 24-72h).	NVR/server failure is a single point of failure unless you cluster. Hardware dies, you replace; in the meantime, no recording.
Compliance fit	Strong for HIPAA (with BAA), PCI-DSS, FERPA. Weaker fit for CMMC L3+, certain ITAR, and customers whose policy says video stays on-prem.	Strong for CMMC, ITAR, on-prem-only data-sovereignty mandates, and customers who want full physical custody of footage.
Upgrade cadence	Vendor pushes updates continuously. New features arrive without IT effort. You also accept the changes you didn't ask for.	IT controls the upgrade window. Major VMS upgrades happen on your schedule. Trade is that lagging customers fall behind on features.
Recovery from failure	Camera dies, replace it; cloud takes over. Server failure isn't your problem. Internet failure breaks live view but edge buffers usually retain recent footage.	You own the runbook: spare NVR, RAID rebuild, storage expansion, OS reinstall. Faster local recovery with a team, slower without.

§02 Where Cloud-managed wins

Choose cloud-managed when these matter most.

Multi-site enterprise without per-site IT

Retail chains, K-12 districts, healthcare clinics, multi-location hospitality. You can't put an IT person at every site. Cloud collapses the operations footprint to a single pane.

Fast deployment

Plug a camera into a PoE port, claim it in the dashboard, and recording starts. New-site rollouts measure in days, not weeks. No server build, no VMS install, no firewall ticket.

Predictable budgeting and lean IT signoff

Per-camera annual subscription line-items cleanly in opex, so budgets stay flat year over year. Cameras initiate outbound to the cloud: no port forwarding, no DMZ, no inbound firewall conversation. IT approves cloud video faster than on-prem VMS in most environments.

Vendor-managed upgrades and redundancy

Features and patches arrive continuously without IT effort, so you skip the multi-month VMS upgrade project on-prem customers run every few years. The vendor cloud handles backup, replication, and DR; edge buffering covers short internet outages, so you don't run a second NVR for failover.

§02 Where On-prem wins

Choose on-prem when these matter most.

Regulated data sovereignty

Defense contractors with CUI, certain healthcare networks, financial institutions whose policy says video stays inside the building. On-prem is the answer when "must not leave the network" is a hard requirement.

Large camera counts and strong internal IT

Stadiums, transit hubs, ports, manufacturing campuses with 500+ cameras at one site. Per-camera SaaS economics break here; the server amortizes across many cameras and the math swings to on-prem. Customers already running VMware, on-prem identity, backup, and a NOC have the muscle to run another server.

Integration with on-prem identity / VMS infra

Active Directory, on-prem access control (Lenel, Software House CCURE, AMAG), legacy intercoms, on-prem PSIM. Genetec and Milestone integrate natively with this stack. Cloud platforms can integrate, but the surface area is smaller.

Long retention and camera-vendor flexibility

Investigation-heavy industries (transit, gaming, large security ops) often want 180-365 days of retention, bounded only by your shelves on-prem versus a paid cloud tier. Milestone, Genetec, ExacqVision, and Axis Camera Station are camera-agnostic via ONVIF, so you can mix Axis, Hanwha, Bosch, and others on one VMS. Cloud platforms generally lock you to their hardware.

§03 What each architecture is

Cloud-managed and on-prem VMS, defined.

Cloud-managed: cameras stream to a vendor-operated cloud over the internet. The dashboard is a SaaS app. No on-prem server, no NVR, no Windows box to patch. The vendor handles updates, infrastructure, and uptime; you handle cabling, camera placement, and the per-camera license. Examples: Verkada (single-pane multi-site), Eagle Eye Networks (the most camera-agnostic), Rhombus and Spot AI (AI-forward), and Avigilon Alta (connects to the broader Motorola Solutions stack).

On-prem traditional VMS: cameras connect to a server you own, running a VMS you license, with footage stored locally on RAID or SAN. Your IT team owns the server, OS patching, VMS upgrades, and storage refresh, and footage stays inside your network. Examples: Milestone XProtect and Genetec Security Center (multi-site enterprise champions), Johnson Controls ExacqVision (strong in mid-market and education), OnSSI (now part of Qognify), Hanwha Wisenet WAVE on-prem (pairs natively with Hanwha cameras), and Axis Camera Station (the simpler small-to-mid path with Axis hardware).

§04 Hybrid reality

Most large enterprise installs are hybrid.

The honest enterprise answer: cloud at branches and smaller sites, on-prem at HQ or the data center. A 200-location retailer with two distribution centers usually lands here, as does a multi-campus hospital network or a defense contractor with one classified facility and ten admin offices.

Small sites can't justify a server and an IT person, so cloud wins there. Large flagship sites have IT, compliance, and camera-density economics that swing on-prem. Forcing one architecture across both site classes leaves money or compliance on the table. Tec-Tel installs both and designs the architecture per site class, documenting the reason in the deployment plan.

The one tradeoff hybrid carries: two dashboards. Some customers stitch them together with Genetec Security Center as a unifying VMS that ingests both feeds; others run a Physical Security Information Management (PSIM) layer. Many just accept the two-pane reality because the savings outweigh the polish hit.

§05 Compliance fit

How each architecture handles common compliance regimes.

Compliance often dictates the architecture choice before TCO does. Here is how cloud and on-prem typically handle five regimes that touch most US commercial buyers. These describe how Tec-Tel installs are commonly designed and are not legal advice.

HIPAA Security Rule (45 CFR 164 Subpart C): Cloud fits with a Business Associate Agreement (BAA), which major providers will sign; network segmentation between camera traffic and clinical systems is standard. On-prem fits naturally since footage stays inside the network, no BAA needed for the video itself. Source: HHS.gov.

PCI-DSS (v4.0): Both architectures pass Requirement 9 (physical access) when cameras cover the cardholder data environment and access is logged. 90-day retention minimum applies. On-prem retention is bounded by your storage, cheaper than cloud for long retention at scale. Source: PCI Security Standards Council.

CMMC 2.0 (32 CFR Part 170 + NIST SP 800-171): CMMC Level 3 generally requires FedRAMP-Moderate (or higher) authorization for any cloud system holding CUI, and most commercial cloud video providers are not there today. On-prem is the cleanest path for L2/L3; NIST 800-171 PE-1 through PE-6 controls map naturally to on-prem video on a controlled network. Source: DoD CIO.

NDAA Section 889: This is a vendor question, not an architecture question. Verkada, Avigilon Alta, Eagle Eye Networks, Rhombus, and Spot AI publish 889 statements. Milestone, Genetec, ExacqVision, Wisenet WAVE, and Axis are all NDAA 889-compliant. The non-compliant names (Hikvision, Dahua, Lorex, Hytera, Huawei, ZTE) span both architectures and must be excluded. Source: FAR 52.204-25.

GDPR (EU 2016/679, US-touching): Cloud requires a Data Processing Agreement, lawful-basis documentation, and region selection that respects EU data residency where applicable. On-prem is easier for EU residency since footage doesn't cross borders by default. DPIA still required for facial recognition. Source: gdpr.eu.

§06 5-year TCO realism

Total cost of ownership over 5 years.

Day 1 sticker rarely tells the real story. Benchmark either architecture's quote against the 5-year TCO.

Cloud-managed: camera hardware (one-time) plus per-camera annual SaaS license over 5 years. Long retention tiers, premium camera SKUs, and add-on modules (alarms, access, intercom) pull the number up; longer contract terms (3-year and 5-year discounts) and volume tiers pull it down.

On-prem: camera hardware plus VMS license (typically perpetual + annual maintenance) plus amortized server, storage, and rack costs over 5 years. The per-camera number is lower, but the Day 1 capex spike and IT-owned operating cost are real. Server clustering, storage redundancy, and high-end VMS (Genetec Security Center Pro tier) pull it up; large camera counts and in-house IT pull it down.

These brackets exclude cabling, install labor, design fees, and project management, which are similar across architectures. They also exclude internal IT effort to run on-prem (typically 0.1 to 0.25 FTE for a mid-sized deployment), which moves the on-prem number up if you account for it honestly. We model both side by side during the free consultation using your actual deployment shape.
